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

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