Applications & Usage

Equal sides carry load about both axes, so this square hollow section is specified for columns, posts, gates, and frames, and the closed section resists torsion better than an open profile of similar weight. Supplied black, with a red-oxide shop primer, or hot-dip galvanized; the internal weld bead can be removed on request on most sizes.
