Carbon Steel Square Pipe
HIGH QUALITY PRODUCTS
Carbon Steel Square Pipe
Carbon Steel Square Pipes are hollow, square-shaped tubes made from carbon steel, typically produced through seamless or welded processes. These pipes feature a square or rectangular cross-section, providing structural support and versatility in applications where round pipes may not be suitable. They can vary in dimensions, wall thickness, and length to meet specific requirements.
