Hot-rolled Q355B equal angle for steel structures, towers, إطارات, brackets and general fabrication.
Q355B carbon steel angle bar is a hot-rolled equal-angle section of low-alloy high-strength structural steel. It combines 355 MPa yield strength with good weldability, and is used where Q235 angle is too weak.
