SHS questions

What is the difference between SHS and RHS steel tubes?

SHS, or square hollow section, has four equal sides, such as SHS 40x40 mm. RHS, or rectangular hollow section, has a longer and a shorter side, such as RHS 50x100 mm. SHS is equally stiff in both directions, so it suits posts and bracing. RHS is stiffer when set with its deeper side upright, so it suits beams that bend mainly one way.

What SHS sizes does GBTL make for solar mounting structures in Bangladesh?

GBTL makes SHS 40x40, 50x50, 60x60 and 75x75 mm for solar mounting structures in Bangladesh. Solar SHS walls run from 2.0 to 4.0 mm, and the 4.0 mm wall is offered on SHS 75x75 mm only. Standard solar SHS sizes have a 2 MT minimum order. Any other SHS size needs a full coil run of 20 MT.
