Q235B Q355b Hot Rolled U Channel Steel for Building Frame Project

Crafted by standard hot rolling process with stable section dimension tolerance, neat surface and uniform structure, convenient for cutting drilling and welding processing.

Made of carbon steel grades Q235B Q355B A36 SS400 complying with GB ASTM EN JIS standards. It has good bearing capacity tensile strength and excellent weldability for structural projects.

Available in black pickled surface or hot dip galvanized finish. Galvanized channel steel effectively prevents rust and adapts to outdoor humid and corrosive environments.

Full sizes from 5# to 40# U channel are supplied, standard length 6m 9m 12m, custom saw cutting service supported.

Each batch passes dimension chemical and mechanical testing before shipment. Mill test certificate is available and third party inspection is accepted.

Support fixed length cutting punching bending and drilling according to customer drawings to reduce on site construction work.

Widely used in building frames solar brackets warehouse racks machinery base curtain wall and municipal engineering.

Large stock ensures short delivery cycle. Bundled with steel strips and waterproof packing to avoid deformation and scratch during sea transportation.

Reasonable U-shaped cross section improves bending resistance, achieves stable load bearing with less steel consumption, and effectively controls overall project cost.

Standard size tolerance enables smooth matching with angle steel I beam and steel plate, convenient for on site assembly and modular construction.
