Hebei metal Ltd. is a construction materials company, which includes new product development, manufacture, sale and engineering service.Our core product are seamless steel pipes, welded steel pipes,buttweld pipe fitting and steel pipe flanges.

Hot-dip welded square pipes offer superior corrosion resistance, high load-bearing capacity, and long service life, making them ideal for construction, infrastructure, and industrial applications. They ensure structural safety, durability, and low maintenance costs.

​We offer black-painted seamless steel pipes in a variety of size ranges to meet different diameter requirements. The product materials include multiple high-quality carbon steel grades, such as ASTM A53 Gr.B, ASTM A106 Gr.B, and API 5L Gr.B. Additionally, we provide high-strength API 5L series pipes to meet more demanding operational conditions.

Black hollow steel refers to hollow steel that has not undergone galvanization or surface coating treatment. Its surface presents a natural black oxide film, which provides a good foundation for corrosion resistance. According to the different cross - sectional shapes, black hollow steel can be mainly divided into three types: circular, square, and rectangular. They are widely used in load - bearing structures and space frames to meet the requirements of different architectural forms and engineering projects.
