COMPANY HISTORY

Fine plating technology
for the future and society
SAKURATECH aims at contributing to every application and industrial society

Steel wire

November 1939 Sakura Steel Wire Co., Ltd., founded inHigashi Osaka City, Osaka Prefecture;
started production of stainless steel wire
and other special steel wire
April 1948

Converted to production of flexible steel wire
products (mainly galvanized steel wire)

October 1972

First company in Japan to succeed in thecommercialization of ultra thick galvanizedsteel wireFebruary 1977

Constructed a high-speed galvanizing plantin Kani City, Gifu Prefecture in association
with increased demand for ultra thickgalvanized steel wire (introduced gas wiping
technology from AWI of Australia), enabling
the production of wire with a zinc coating
weight of 500g per square meter

October 1991

Company changed name toSAKURATECH Co., Ltd.

July 1993

Reacquired the license to display “JIS G 3532
steel wire” and “JIS G 3547 Galvanized steelwire” in association with the amendment
and institution of the JIS; started sales ofzinc-aluminum alloy galvanized steel wire

Galvanized layer

April 2007

Closed Osaka Plant and concentrated
production at Gifu Plant

The galvanized layer not only shields
the steel wire from the external environment,
but also has the function of protecting the ironfrom corrosion as the zinc corrodes preferentially.
The thickness of this layer determines
the lifetime of galvanized steel wire.

July 2008

Received certification for the new JIS markdisplay system

April 2009

Developed rough galvanized steel wire to
the new standard of the Ministry of Land,Infrastructure, Transport and Tourism

SAKURATECH’s ultra thick galvanized steel wire
uses only high quality materials purchased fromthe strictly selected manufacturers.
We pursue various properties thoroughlyin accordance with the application andenvironment of use, etc.

as a pioneer of ultra thick galvanization technology,
and continues to supply to all job sites, and fields from civil engineering
to everyday items through the development, manufacture and sale of wire products.
We will lead the future of galvanized iron and steel wire through the trustand achievements that we establish continuously as a high valued planningand development company.

Our wire is coated with several times more zinc than other commerciallyavailable wire, making durable lifetimes several times longer too.

Point

1. Longer lastingPointwire is economical because it is so long-lasting
2. More economical Our
and very rarely needs replacing.

Point

3. Easier to use

Our wire has great formability and the plating
will not flake off however much the wire is bent.

Point

4. Better looking

Our wire does not rust. It does not break andkeeps its beautiful luster for a long time.

01 SAKURATECH Co.,Ltd.

Iron-zinc alloy layer
Iron and zinc form an alloy easily at hightemperatures and an iron-zinc alloy layer isformed on the surface of galvanized steel wire.
This alloy layer is hard and brittle.
SAKURATECH controls the thickness of thislayer in accordance with the application toincrease the strength of the plating and
its workability.

Manufacturing process

We create the best productswith a uniform production system.
SAKURATECH has used the company’s many years of experience in pioneering
ultra thick galvanized steel wire and establishing an extremely intelligent
uniform system for everything from the procurement of materials
to the drawing of wire, galvanization and product inspection.
We practice strict quality control across all processes to create
unique products that cannot be mimicked by our competitors.

We order various materials
matched to the application fromcarefully selected wire material
manufacturers and carry out
acceptance inspections of thetype of packing and external
appearance, etc. In addition, wealso carry out material inspections
that check the adequacy of thewire rods.

In the annealing process thatsoftens the drawn out steel wire
we adjust the temperature
settings and processing timein accordance with the productcategory and size. Also, in thegalvanization process, we canproduce products of all grades
using various technologies such as
the gas wiping method, etc.
After galvanization, the wire iswound onto carriers.

We inspect whether or not
products clear the designatedspecifications such as wire diameter,
tensile strength, elongation,
zinc coating weight, etc.
