Summary:
Thin sheet steel products are extensively used in
building industry, and range
from purlins to roof sheeting and floor decking. Generally
these are available for use as basic building elements
for assembly at site or as prefabricated frames or panels.
These thin steel sections are cold-formed, i.e. their
manufacturing process involves forming steel sections
in a cold state (i.e. without application of heat) from
steel sheets of uniform thickness. These are given the
generic title Cold Formed Steel Sections. Sometimes they
are also called Light Gauge Steel Sections or Cold Rolled
Steel Sections. The thickness of steel sheet used in cold
formed construction is usually 1 to 3mm. Much thicker
material up to 8 mm can be formed if pre-galvanised material
is notrequired for the particular application. The method
of manufacturing is important as itdifferentiates these
products from hot rolled steel sections. Normally, the
yield strength of steel sheets used in cold-formed sections
is at least 280 N/mm2, although there is a trend to use
steels of higher strengths, and sometimes as low as 230
N/mm2.
