                                                                  EXHIBIT 4.6

                            JUNIOR SECURITY AGREEMENT

            JUNIOR SECURITY AGREEMENT (this "Agreement"), dated as of June 11,
2001, between FLOUR CITY ARCHITECTURAL METALS, INC., a Delaware corporation
whose address is 1044 Fordtown Road, Kingsport, TN 37663 (the "Debtor"), and
DIMENSIONAL PARTNERS, L.P. and DIMENSIONAL PARTNERS, LTD. (together with any
permitted assigns of the Debentures (as defined below), the "Secured Parties").

                                   WITNESSETH:

            WHEREAS, simultaneously herewith, Flour City International, Inc., a
Nevada corporation (the "Issuer"), is issuing its 8 1/2% Subordinated Secured
Convertible Debentures due 2004 in favor of the Secured Parties in an aggregate
principal amount of $2,500,000 (the "Debentures");

            WHEREAS, the Debtor is a wholly-owned subsidiary of the Issuer and
will receive considerable benefit from the sale of the Debentures by the Issuer,
the proceeds of which sale will be used for working capital purposes by the
Issuer and its subsidiaries;

            WHEREAS, as a condition to the purchase of the Debentures by the
Secured Parties, the Debtor has guaranteed the obligations of the Issuer under
the Debentures pursuant to a Guaranty in favor of the Secured Parties dated as
of the date hereto (the "Guaranty"); and

            WHEREAS, in order to induce the Secured Parties to purchase the
Debentures and to secure the Debtor's performance and payment under the
Guaranty, the Debtor has agreed to execute this Agreement.

            NOW THEREFORE, the parties hereto agree as follows:

            1. SECURITY INTEREST. As collateral security for the prompt and
complete payment and performance when due of its obligations under the Guaranty
and the prompt performance and observance of all the covenants contained therein
and in this Agreement, the Debtor hereby grants to the Secured Parties a
continuing security interest in and lien on all of the Debtor's right, title and
interest in, to and under all of the Collateral (as defined below), including
all accessions to the Collateral, substitutions and replacements thereof, now
owned or existing and hereafter acquired, created or arising, and all products
and proceeds thereof (including, without limitation, claims of the Debtor
against third parties with respect to any Collateral). The "Collateral" shall
consist of all accounts, receivables, accounts receivable, book debts and rights
to payment no matter how evidenced, and other obligations of any kind, now or
hereafter existing, arising out of or in connection with the sale or lease of
goods or the rendering of services by the Debtor, any of its subsidiaries or
Flour City International, Inc. in the United States; and all proceeds of every

<PAGE>

kind and nature, including proceeds of proceeds, of any and all of the foregoing
Collateral, including money and cash.

            2.  REPRESENTATIONS AND WARRANTIES.  The Debtor hereby represents
and warrants that:

            (a) Except for the security interest granted pursuant to this
Agreement and as set forth on Schedule A hereto, the Debtor is the sole owner of
the Collateral, having good and valid title thereto, free and clear of any and
all liens and encumbrances.

            (b) The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby to be performed by the
Debtor have been duly and validly authorized by the Board of Directors of the
Debtor and no other corporate proceedings on the part of the Debtor are
necessary to authorize this Agreement or to consummate the transactions so
contemplated. The Debtor has all corporate power and authority to execute and
deliver this Agreement, to consummate the transactions hereby contemplated and
to take all other actions required to be taken by it pursuant to the provisions
hereof; and this Agreement is the legal, valid and binding obligation of the
Debtor, enforceable against the Debtor in accordance with its terms.

            (c) Except for the filing of UCC-1 financing statements in order to
perfect the security interest granted hereunder, no consent, approval,
authorization or notification of, or declaration, filing or registration with,
any governmental entity is required on behalf of or on the part of the Debtor in
connection with the execution, delivery, or performance of this Agreement and
the consummation of the transactions contemplated hereby by the Debtor. Neither
the execution and delivery of this Agreement by the Debtor nor the consummation
of the transactions hereby contemplated to be performed by the Debtor will (i)
constitute any violation or breach of the Certificate of Incorporation or
By-Laws of the Debtor, (ii) violate, or constitute a default under, or permit
the termination or acceleration of the maturity of, any indebtedness for
borrowed money of the Debtor, (iii) violate, or constitute a default under, or
permit the termination of, any license, contract, lease or other instrument to
which the Debtor is a party or by which the Debtor or any of its properties is
subject or by which any of them is bound, or (iv) violate any order, writ,
injunction, decree, statute, rule or regulation, governmental license or permit,
to which the Debtor or any of its properties is subject or by which any of them
is bound.

            (d) The Debtor is a corporation duly organized, validly existing and
in good standing under the laws of the State of Delaware.

            (e) The address set forth at the beginning of this Agreement is the
Debtor's chief executive office. All books and records of the Debtor and its
subsidiaries with regard to the Collateral are maintained and kept at such
address of the Debtor set forth at the beginning of this Agreement.

            3.  COVENANTS.  The Debtor hereby covenants as follows:

            (a) The Debtor shall pay all reasonable expenses and reimburse the
Secured Parties for any reasonable expenditure, including reasonable attorneys'
and accountants' fees,

                                       2

<PAGE>

including attorneys' fees incurred in any appellate or insolvency
proceedings, in connection with the Secured Parties' exercise of their rights
and remedies herein or contained in the Guaranty.

            (b) The Debtor shall execute and deliver, or cause to be executed
and delivered, to the Secured Parties those documents and agreements, including
without limitation, Uniform Commercial Code financing statements, and shall take
or cause to be taken those actions that the Secured Parties may, from time to
time, reasonably request to carry out the terms and conditions of this Agreement
and the Guaranty.

            (c) Except for liens or other charges or encumbrances securing the
Senior Debt (as defined in the Debentures), including the other security
interests, liens and encumbrances listed on Exhibit A hereto (collectively, the
"Permitted Senior Liens"), and liens made in the ordinary course of business and
not securing indebtedness for borrowed money, including landlord liens, tax
liens (provided they secure sums being contested in good faith), liens created
under contracts of suretyship entered into in the ordinary course of business
and the like (together with the Permitted Senior Liens, the "Permitted Liens")
the Debtor has not, and hereafter shall not, assign, convey, sell, mortgage,
pledge, hypothecate, transfer, encumber or otherwise dispose of, or grant a
security interest in, the Collateral or any interest therein, without the prior
written consent of the Secured Parties.

            (d) The Debtor will not change its name, identity or organizational
structure in any manner which might make any financing or continuation statement
filed in connection herewith seriously misleading within the meaning of Section
9-402(7) of the New York Uniform Commercial Code (the "UCC"), or any other then
applicable provision of the UCC (as it may be amended or revised from time to
time) unless the Debtor shall have taken all action necessary or reasonably
requested by the Secured Party to amend such financing statement or continuation
statement so that it is not seriously misleading. The Debtor will not change its
principal place of business, remove its records from such place or change its
state of incorporation unless the Debtor shall have given the Secured Party at
least 30 days' prior written notice thereof and shall have taken such action as
is necessary to cause the security interest of the Secured Parties in the
Collateral to continue to be perfected. The Collateral shall not be located at
any location except as is specified in Section 2(e) hereof without the prior
written consent of the Secured Party.

            (e) Provided the Secured Parties maintain the confidentiality
thereof and do not use any such information in violation of any laws (including
securities laws), the Debtor agrees to furnish to the Secured Parties, from time
to time on reasonable advance written notice, such information relating to the
Collateral as the Secured Parties may reasonably request.

            (f) Prior to or concurrently with the execution and delivery of this
Agreement (and thereafter as may reasonably be required), the Debtor shall file
such financing statements and other documents in such offices as the Secured
Parties may request to perfect the security interests granted by Section 1 of
this Agreement.

            4. CONTINUING SECURITY INTEREST. This Agreement shall create a
continuing security interest in the Collateral securing the Debtor's obligations
under the Guaranty and shall (a) remain in full force and effect until the
payment and discharge in full of the Debtor's obligations under and pursuant to
the terms of the Guaranty, (b) be binding upon the Debtor and

                                       3

<PAGE>

its successors and assigns and (c) inure to the benefit of the Secured
Parties and their successors, transferees and assigns. Upon the termination
of the security interest created hereby pursuant to clause (a) above, the
Secured Parties shall, at the Debtor's request and expense, deliver to the
Debtor a release of all security interests granted by the Debtor to such
Secured Party pursuant to this Agreement.

            5. REALIZATION UPON COLLATERAL. If the Debtor shall fail to perform
any of its obligations under the Guaranty when due under the terms of the
Guaranty (an "Event of Default"), the Secured Parties shall have all of the
rights of a secured party under the Uniform Commercial Code as in effect in the
State of New York, including, without limitation, the right to sell the
Collateral at public or private sale for cash or credit and on such terms as the
Secured Parties deem reasonable. The Secured Parties shall, subject to the terms
of this Agreement and the Securities Purchase Agreement of even date herewith
between the Secured Parties and Flour City International, Inc. (the "Purchase
Agreement"), apply the proceeds of any realization on the whole or any part of
the Collateral after deducting all of their reasonable expenses and costs
incurred in collection and realization (including, without limitation,
reasonable counsel's fees and expenses) to the payment of the Debtor's
obligations to the Secured Parties under the Guaranty; the balance, if any, of
such proceeds shall be paid to Debtor.

            6.  THE SECURED PARTIES' APPOINTMENT AS ATTORNEY-IN-FACT.

            (a) The Debtor hereby irrevocably constitutes and appoints each of
the Secured Parties and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of the Debtor and in the name of the
Debtor or in its own name, from time to time in the Secured Parties' discretion,
for the purpose of carrying out the terms of this Agreement, to take any and all
appropriate action and to execute and deliver any and all documents and
instruments which may be reasonably necessary or desirable to exercise the
Secured Parties' rights with respect to the Collateral, subject to the terms of
this Agreement and applicable law.

            (b) The Secured Parties agree that, except upon the occurrence and
during the continuation of an Event of Default and until any necessary consents
have been obtained, they will forbear from exercising the power of attorney or
any rights granted to the Secured Parties pursuant to this Section 6. The Debtor
hereby ratifies, to the extent permitted by law, all that said attorney shall
lawfully do or cause to be done by virtue hereof. The power of attorney granted
pursuant to this Section 6 is a power coupled with an interest and shall be
irrevocable until the Debentures are paid in full.

            (c) The powers conferred on the Secured Parties hereunder are solely
to protect the Secured Parties' interests in the Collateral and shall not impose
any duty upon them to exercise any such powers. The Secured Parties shall be
accountable only for amounts that they actually receive as a result of the
exercise of such powers and neither the Secured Parties nor any of their
officers, directors, employees or agents shall be responsible to the Debtor for
any act or failure to act, except for their own gross negligence or willful
misconduct.

            7. SEVERABILITY AND ENFORCEABILITY. If any of the provisions of this
Agreement, or the application thereof to any person or circumstance shall, to
any extent, be invalid or

                                       4

<PAGE>

unenforceable, the remainder of this Agreement, or the application of such
provision or provisions to persons or circumstances other than those to whom
or which it is held invalid or unenforceable, shall not be affected thereby
and every provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.

            8. GOVERNING LAW; SEVERABILITY. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York, without
giving effect to principles of conflicts of law (other than Section 5-1401 and
Section 5-1402 of the New York General Obligations Law). Any action or
proceedings to enforce or arising out of this Agreement may be commenced in any
jurisdiction of the federal courts whose districts encompass any part of the
City of New York or the state courts of the State of New York sitting in the
City of New York. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

            9. NOTICES. (a) All notices or other communications to be given

EXHIBIT 4.7

                                    GUARANTY

      GUARANTY, dated as of June 11, 2001, of Flour City Architectural
Metals, Inc., a Delaware corporation (the "Guarantor"), in favor of
Dimensional Partners, L.P. and Dimensional Partners, Ltd. (each, a "Holder",
and, together with any permitted assigns of the Debentures, the "Holders").

            WHEREAS, simultaneously herewith, Flour City International, Inc., a
Nevada corporation (the "Issuer"), is issuing its 8 1/2% Subordinated Secured
Convertible Debentures due 2004 in favor of the Holders in an aggregate
principal amount of $2,500,000 (the "Debentures");

            WHEREAS, the Guarantor is a wholly-owned subsidiary of the Issuer
and will receive considerable benefit from the sale of the Debentures by the
Issuer, the proceeds of which sale will be used for working capital purposes by
the Issuer and its subsidiaries;

            WHEREAS, as a condition to the purchase of the Debentures by the
Holders, the Guarantor is required to guarantee the obligations of the Issuer
under the Debentures; and

            WHEREAS, simultaneously herewith, the Guarantor and the Issuer are
entering into a Junior Security Agreement with the Holders (the "Security
Agreement"), pursuant to which the Guarantor has granted to the Holders a
security interest in its domestic accounts receivable and related collateral
(collectively, the "Collateral") to secure its obligations under this Guaranty.

            NOW, THEREFORE, in consideration of the foregoing and the
agreements, representations and warranties hereinafter set forth, the Guarantor
agrees as follows:

            1.  DEFINITIONS.  Each capitalized term not defined herein shall
have the meaning set forth in the Debentures.

            2. GUARANTY OF PAYMENT. The Guarantor hereby unconditionally and
irrevocably guarantees to the Holders the full and punctual payment, when due,
of all amounts required to be paid by the Issuer under the Debentures
(collectively, the "Obligations"), when and as the same shall become due and
payable, whether at maturity or by acceleration or otherwise. This Guaranty is
an absolute and unconditional guaranty of payment and not of collection only,
and may be enforced by Holders without first resorting to any other right or
remedy which they may have against the Issuer. If the Issuer shall fail to pay
punctually any of the Obligations when and as the same shall become due and
payable, whether at maturity or by acceleration or otherwise, then the Holders
may, without notice to the Issuer or the Guarantor, declare the Obligations to
be due and payable by the Guarantor, and the Guarantor shall forthwith on demand
pay the same in immediately available funds to the Holders.

<PAGE>

            3. COSTS AND EXPENSES. The Guarantor shall forthwith on demand
reimburse the Holders in immediately available funds for all costs and expenses
reasonably incurred by or on behalf of the Holders (including, without
limitation, reasonable accountants' fees and reasonable attorneys' fees and
their respective disbursements and court costs) in enforcing the obligations of
the Guarantor hereunder.

            4. OBLIGATIONS OF GUARANTOR NOT AFFECTED. This Guaranty is a
continuing guaranty and all liabilities to which it applies or may apply shall
be conclusively presumed to have been created in reliance hereon. The
liabilities and obligations of the Guarantor hereunder are primary and
unconditional and shall remain in full force and effect without regard to, and
shall not be affected or impaired in any respect by: (a) any assignment,
transfer, amendment, modification, rescission or cancellation of, or addition or
supplement to, the Debentures; (b) the invalidity, illegality or
unenforceability, in whole or in part, of any of the Debentures; (c) any
exercise, non-exercise, waiver, release or cancellation by the Holders of any
right, remedy, power or privilege under or in respect of any of the Debentures;
(d) any consent, release, extension, indulgence, or any other action, inaction
or omission under or in respect of any of the Debentures or of or with respect
to the Issuer; (e) any receivership, insolvency, bankruptcy, liquidation,
reorganization, arrangement, readjustment, composition, dissolution or other
similar proceeding involving or affecting the Issuer; (f) any sale, exchange,
release, transfer, assignment, conveyance, or other dealing with or disposition
of the Collateral; (g) any improper filing or recording or any failure by the
Holders to file, record or to otherwise perfect or continue perfection of any
lien or security interest in favor of the Holders on any of the Collateral, or
to preserve, maintain or otherwise properly deal with any of the Collateral; (h)
any defense, setoff or counterclaim asserted by the Issuer; or (i) any other
cause or circumstance whatsoever, including, without limitation, any other act,
thing, omission or delay which would or might in any manner or to any extent
vary the risk of the Guarantor or which would or might otherwise operate as a
discharge of the Guarantor as a matter of law, whether or not the Guarantor
shall have notice or knowledge of any of the matters referred to in this Section
4.

            5. WAIVERS AND CONSENTS. Except as otherwise specifically provided
herein, the Guarantor hereby waives: (a) notice of acceptance of this Guaranty
or of any action taken or not taken in reliance hereon; (b) presentment, demand,
notice and protest of any kind with respect to the Obligations; (c) notice of
any of the matters referred to in Section 4 of this Guaranty; (d) all other
notices and demands which may be required by statute, rule or law or otherwise
to preserve any right of the Holders against the Issuer or the Guarantor with
respect to the delivery, acceptance, performance, default or enforcement of this
Guaranty or any of the Debentures, including, without limitation, notice of
protest and dishonor, notice of acceptance, default or non-payment; and (e) any
right of subrogation by virtue of payments made hereunder unless and until the
Holders shall have received full payment of all of the Obligations.

            6. AUTHORIZATION; ENFORCEABILITY; NO VIOLATIONS OR CONSENTS. The
Guarantor represents and warrants that (a) the Guarantor has the power and has
taken all necessary action to authorize the execution, delivery and performance
of this Guaranty in accordance with its terms, (b) this Guaranty has been duly
executed and delivered by the Guarantor and is a legal, valid and binding
obligation of the Guarantor, enforceable against the Guarantor in accordance
with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency or similar laws affecting the enforceability of
creditors' rights generally, and (c) the execution and delivery

                                       2

by it of this Guaranty does not, and the consummation of the transactions
contemplated herein will not, (i) violate, conflict with, or constitute a
breach or default under, with or without notice or lapse of time or both, or
result in a lien or encumbrance upon any of its assets or property pursuant
to, any contract, guaranty, commitment, indenture, lease, order, judgment or
other agreement or instrument to which the Guarantor is a party or by which
it or its assets may be bound, or (ii) require the consent or approval of any
Person.

            7. REINSTATEMENT. This Guaranty shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
the Obligations is rescinded or must otherwise be restored to the Issuer or
returned by the Holders upon the insolvency, bankruptcy or reorganization or
similar proceeding involving the Issuer, or otherwise, all as though such
payment had not been made and notwithstanding the cancellation of the Debentures
or satisfaction and discharge of the Debentures, and the Guarantor shall be and
remain liable to the Holders for the payment so rescinded or otherwise restored
to the same extent as if such payment had never been received by the Holders.

            8. ECONOMIC BENEFITS; SOLVENCY. The issuance and sale of the
Debentures to the Holders constitute indirect economic benefit to the Guarantor
at least equal in value to the obligations imposed upon the Guarantor under this
Guaranty. The guarantee by the Guarantor of the Obligations and the incurrence
by it of its other obligations under this Guaranty and the Security Agreement
will not render the Guarantor insolvent or unable to pay its debts as they
mature or leave the Guarantor with unreasonably small capital. The Guarantor
does not intend to incur debts, including those under this Guaranty, that would
be beyond its ability to pay as such debts mature.

            9. NO WAIVER OR AMENDMENT; CUMULATIVE REMEDIES. No course of dealing
between the Guarantor and the Holders and no failure to exercise or delay in
exercising on the part of the Holders any right, power or privilege under the
terms of this Guaranty, shall operate as a waiver thereof; nor shall any single
or partial exercise of any right, power or privilege hereunder preclude the
exercise of any other or further right, power or privilege. No amendment,
rescission or modification of any provision of this Guaranty shall be effective
unless expressly set forth in a writing duly executed by the Holders. The rights
and remedies provided herein or in the Debenture are cumulative and not
exclusive of, or in derogation of, any other rights or remedies provided at law,
in equity or otherwise. This Guaranty, the Debentures and the Security Agreement
set forth the entire agreement and understanding of the parties with respect to
the subject matter hereof and supersede any and all prior agreements and
understandings of the parties hereto with respect to the subject matter hereof.

            10.  SUCCESSORS AND ASSIGNS.  This Guaranty shall be binding
upon, and shall inure to the benefit of and be enforceable by, the respective
successors and assigns of the Holders and the Guarantor but the Guarantor may
not assign any part of its obligations hereunder.

            11.  TERM OF GUARANTY.  This Guaranty shall remain in full force
and effect until the Obligations have been paid and discharged in full.

prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. To the extent permitted
by applicable law, the Guarantor hereby waives any provision of law which
renders any provision hereof prohibited or unenforceable in any respect.

            14.  GOVERNING LAW.  This Guaranty shall be governed by the
laws of the State of New York, without reference to its principles of
conflicts of laws (other than Section 5-1401 and Section 5-1402 of the
New York General Obligations Law).

            15.  COUNTERPARTS.  This Guaranty may be executed in any
number of counterparts, each of which so executed shall be deemed an
original, but all such counterparts shall together constitute but one
and the same agreement.
