 Foreword  
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered when goods and services are exchanged 
within the Community will be removed.  
In order to achieve this objective, the Community established an East African Standards Committee mandated 
to develop and issue East African Standards.  
The Committee is composed of representatives of the National Standards Bodies in Partner States, together 
with the representatives from the private sectors and consumer organizations. Draft East African Standards 
are circulated to stakeholders through the Nati onal Standards Bodies in the Partner States. The comments 
received are discussed and incorporated before finalization of standards, in accordance with the procedures 
of the Community.  
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing.  
 DEAS 134 :2018  was prepared by Technical Committee EASC /TC 035 TC Steel and Steel Products

 Cold rolled steel sections ― Specification  
1. Scope  
 
This East Africa Draft Standard  specifies the dimensions and sectional properties of  cold rolled steel sections 
of thickness up to 8 mm for use in structural  and general applications. The sections are listed in Tables 4 to  
15. 
 
2. Normative references  
The following referenced document is indispensable for the application of this document. Fo r dated 
references, only the edition cited applies. For undated references, the latest edition of the referenced 
document (including any amendments) applies.  
 
ISO 14347, Fatigue — Design procedure for welded hollow -section joints — Recommendations  
3.  Terms and definition  
No terms and definition are listed in this document.  
 
4. Symbols  
The following nomenclature shall be used. Units for dimensions are millimetres and those for section 
properties in centimetres.  
  t  -   section thickness     -  mm  
  p  -  distance from edge to  section centre of gravity   mm  
 A  -  sectional area     -  cm2 
 Z  - section  modulus of section l/p     cm3 
 I  -  second moment of area   -   cm4 
 r  - radius of gyration of section

5 Compound sections  
Compound sections may be formed by suitably connecting two or more simple sections. For example, an 'I' 
section can be made from two channels back -to-back, a tube from two inwardly lipped channels lip -to-lip, a 'T" 
from two angles, etc. Methods of joining sections are specified in ISO 14347.  
Section properties of compound sections may be calculated using the properties of simple sections.  
Compound sections shall be flush at matching joints within 2.0 mm.  
 
6 Manufacture  
6.1 Manufacture of steel  
Unless otherwise agreed at the time of enquiry and order, the steel making process shall be at the option of 
the manufacturer. If so requested in the order, the purchaser shall be informed about the steel making process 
used.  
 
    DEAS 134 :2018  
 6.2 Grade designation  
The designatio n of the grades of material shall be based on minimum permissible yield stress and shall be in 
accordance with Table 1.  
Table 1 — Grade designation

N/mm2 Designation of grade  
210 210

6.3 Chemical composition  
The results of ladle chemical analysis of steel from which a hollow section is manufactured shall comply with 
appropriate limits of Table 2. For grade 360, it shall be permissible to add suitable grain -refining elements to 
achieve the minimum specified ten sile stress, but the total content of these elements shall not exceed 0.15 %.

6.4 Mechanical properties  
The mechanical properties obtained from test samples taken from the hollow section in accordance with 6.5, 
shall comply with the requirements in Table 3. If other grades of steel are used, their mechanical properties 
shall be agreed o n between the purchaser and the manufacturer.

6.5 Sampling  
6.5.1 General  
 
At least one sample shall be selected from the following batch sizes:  
a) a 20-tonne or less batch of sections having outside diameter of less than 90 mm; and  
 
b) a batch of less than 40 tonnes for all other sections.      DEAS 134 :2018  
 If the test fails, two more samples shall be drawn from the batch and tested. If one or both test specimens re -
tested fail, the whole batch shall be deemed not to have complied with the specification u nless all sections in 
the batch are tested individually.  
 
6.5.2 Test pieces  
The test piece shall consist of a strip taken from the section. The strip shall be taken longitudinally at any point 
of the section except for welded sections when it shall not be taken from the weld zone. The strip shall comply 
with the following conditio ns:  
a) sides of the test piece shall be parallel within a maximum variation, along parallel length, of ± 0.2 % of 
nominal width;  
b) the tripped ends and parallel lengths of the test piece shall be coaxial;  
c) 
A L 5.65o  and shall be within ± 5 % of the nominal value:  
where  
Lo is the gauge length, and  
A is the sectional area.  
d) minimum parallel length Lp = Lo + 2D for circular sections, and Lp = Lo + 2 nominal width for square or  
rectangular sections:  
where,  
Lo is the gauge length;  
e) the width of the test piece shall not be less than 6 mm, unless the product width precludes use of 
wider pieces; and  
f) the test piece shall not be flattened and machined between the gauge marks except for the purposes 
of gripping the te st piece in a test machine.  
 
7. Marking  
Each piece shall be indelibly and legibly marked /printed at least once in every 6 meters length with the 
following  
i) Manufacturer’s name and/ or registered trademark  
ii) The outside dimension  
iii) Nominal thickness  
iii) The steel grade  
iv) Country of origin
