S460GDRF High-strength hot-dip galvanised steel - Tata Steel 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 Table 1: Mechanical properties Grade R p 0.2 (N/mm 2 ) Min R m (N/mm 2 ) Min A 80 (%) S460GDRF 460 480 5 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 Table 3: Dimensions Thickness (mm) Width (mm) ≥ < Max 0.90 2.50 1375 Note: For lower thicknesses please contact Tata Steel Table 2: Chemical analysis Grade C Mn P S Si Max Max Max Max Max S460GDRF 0.2 1.7 0.1 0.045 0.6 Note: Values are in weight percentages Table 4: Dimensional tolerances against BS EN 10143: 2006 Tolerances Thickness Normal, special or 50% Width Normal Note: For other tolerances please contact Tata Steel Table 5: Coating weights and surface quality Coating designation Thickness (mm) Surface quality 275 consult Tata Steel MA preferred
