The steel pipes for construction (building pipes) can be divided into seamless steel pipes and seamed steel pipes according to seamless seams. Spiral steel pipes are divided into spiral steel pipes and straight seam steel pipes according to the weld seams. They are widely used in construction piling, structure, steel structure, load-bearing and drainage.
The materials are mainly carbon steel, stainless steel and alloy steel. Among them, the application of carbon steel is the most common, and the main production base is in Cangzhou, Hebei. According to the customer's requirements, the length of the steel pipe can be fixed, or the ruler can be used. The price of the fixed ruler is more expensive than the loose ruler per ton.
