New Standard from Last Update.

1. SCOPE

1.1 This standard covers the requirement of steel including microalloyed steel plates, strips, shapes and sections (angles, tees, beams, channels, etc), flats, bars, etc, for use as hot dip galvanized structural.

1.1.1 This steel is suitable for welded, bolted and riveted structures which is used in variety of applications including transmission line towers.

1.1.2 Where welding is employed for fabrication and guaranteed-weldability is required, welding procedure should be as specified in IS 9595.
