We will control the quality from part of material steel pipe, each pipe produced will be have it is own identify label, quality will check the chemical component and physical property and then provide material test certificate. Size dimension will be checked and show pictures to customer to guarantee all goods will be meet requirement.
Our company is a steel supplier from China, located in Tianjin City, one of the largest steel producers in China. The company integrates the manufacturing, wholesale, material processing and warehousing of stainless steel, aluminum, copper and carbon steel materials, and has established long-term and stable cooperative relations with many well-known steel plants, such as Tisco, Baosteel, Hongwang, Zhangpu, Liangzhong and Jiugang.
The special-shaped seamless steel pipe is widely used in various structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe has larger inertia moment and section modulus, larger bending and torsion resistance, which can greatly reduce the structure weight and save steel.
1) Packaging: 3 layers of packing. Inside is craft paper, Middle is water plastic film and outside GI steel sheet to be covered by steel strips with lock, with inner coil sleeve or as customers' requirements.
