QIDAMT · CARBON STEEL ANGLE
Q355B碳钢角钢 – 低合金等角
Hot-rolled Q355B equal angle for steel structures, 塔, 框架, 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.
主要优势
高力量
355 兆帕产量, supports heavier loads.
可焊接
Easy welding for trusses and frames.
Wide Sizes
20×20 to 200×200 mm equal angle.
成本效益
Cheaper than stainless or alloy angles.
