1 Scope This standard specifies the dimension, appearance, weight and permissible deviation, technical requirements, test methods, test rules, packing, marking and quality certificate of atmospheric corrosion resisting structural steel. This standard is applicable to hot-rolled and cold rolled steel plate, flat strap and section steel with resistance to atmospheric corrosion capacity for vehicle, bridge, freight container, building, tower pier and other structure appliance. Atmospheric corrosion resisting steel can be used for making bolted connection, rivet joint and welded structure component. 2 Normative References The following documents contain provisions which, through reference in this text, constitute provisions of this code.
