S460GDRF High-strength hot-dip galvanised steel - Tata Steel

S460GDRF is an extension to Tata Steel’s
hot-dip galvanised (HDG) structural steel family.
It has been developed in response to the
requirements of both leading cold-formed section
rollers and construction sector component and
system manufacturers.
S460GDRF offers improved value for applications
with high strength and limited formability
requirements.
Typical applications:
This high strength metallic-coated product is used for a range of
construction applications, including:
• Purlins and side rails
• Floor decking
• Industrial storage tanks
• Mezzanine flooring
Benefits:
The application of this product allows customers to exploit a range of
associated benefits, including:
• Excellent strength/weight ratio
• Good formability suitable for most rolled formed sections
• A cost effective solution
• Easier and safer handling of components on-site
• Associated environmental benefits including improved carbon footprint

Notes:
1. Values are based on test pieces taken in the longitudinal direction
2. Tensile values relate to test piece cross sections without zinc coating
3. The index of elongation indicates the original gauge length used, expressed in
millimetres, e.g. A 80
indicates an 80mm gauge length
