500×500×10 mm S235JRH Steel Square Hollow Section
500x500x10mm cold-formed ERW square hollow section to EN 10219, rolled in S235JRH, S275J0H or S355J2H depending on size, supplied with an uncoated steel surface suitable for further processing or painting.
Minimum order
Minimum 10 t per size. If the size is already in the current production cycle, we can accept orders from 5 t. Standard length 6 m; 4–12 m on request. We confirm the minimum, lead time and grade in your quote.

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.
