Profiled steel sheets for roofing and siding applications - Specification (30 page(s), in English)

This standard specifies minimum requirements for metallic-coated steel sheets profiled for roofing and siding applications. It includes requirements for:

1.    plain sheet characteristics including base metal thickness, tensile strength and yield strength;

2.    metallic coating characteristics including coating type and coating mass;

3.    paint coating characteristics including resistance to colour change and chalking;

4.    profiled sheet dimensional characteristics including length, squareness, and tolerances;

5.    labelling; and

6.    compliance (see Annex A).

This standard applies to unpainted and pre-painted profiled steel sheets of minimum base metal thickness of 0.36 mm hot-dip coated with zinc and aluminium-zinc or aluminium-zinc-magnesium alloy. This standard does not apply to other construction products made by the cold forming of steel sheets such as furring channels and load bearing products including floor decking sheets and purlins.
