Large Size Architectural Structural Steel Fabrication / Welding Steel Building Structures

Large Size Architectural Structural Steel Fabrication / Welding Steel Building Structures. We have three steel structure production lines, equipped advanced CNC machine such as plasma cutting machine, flame cutting machine, H-Section steel assembly machine, gantry welding machine and shot-blasting machine, paint spray booth. We also put apart the space for the fabrication of heavy-duty and large structure steel components in our workshop.

We could welded large size or special-shaped steel structre including H-section steel, latticed steel, cross-shaped steel, box-shaped steel, arc-shaped steel, large diameter seamless welding pipe.
