Weldable structural steels. Hot finished structural hollow sections in weather resistant steels. Specification not-for-sale Recommendations for maintenance of the1 Scope This British Standard specifies the technical delivery requirements for weldable weather resistant hot finished seamless, electric welded and submerged arc welded (longitudinal or helical) steel structural hollow sections of circular, square, rectangular or elliptical forms. It applies to hollow sections formed hot with or without subsequent heat treatment, or formed cold with a subsequent full body heat treatment to obtain equivalent
