Our factory supplies St52, A53 Gr.B, Q345B and other structural grade seamless steel pipes. The whole production process adopts fine rolling and normalization heat treatment to eliminate internal stress, ensuring the pipe body is not easy to crack or deform during mechanical processing and long-term load-bearing use. The product has flat pipe ends, smooth surface and no processing defects.
It is widely used for mechanical equipment brackets, engineering machinery structural parts, vehicle frame accessories, steel structure workshop supports, hydraulic equipment outer tubes and hardware processing parts. We support non-standard size customization, fixed-length cutting, pipe end flattening, grooving and other deep processing. With stable inventory and mature export system, we provide high-quality structural pipe materials for global machinery manufacturers and steel structure engineering projects.
