Product Details

The square pipe is divided into seamless and welded seams, and the seamless square pipe is extruded from the seamless round pipe. Common square pipes are welded or non-welded. Square tube is the strip steel through the process of rolling, generally the strip is unpacked, flat, crimped, welded to form a round tube, and then rolled from the round tube into a square tube and cut to the required length.

Square tube As the name suggests, it is a kind of square shape of the tube, a variety of materials can form a square tube body, its medium in, what to use, where to use, most of the square tube to the majority, after unpacking, leveling, crimping, welding to form a round tube, and then rolled by the round tube into a square tube and then cut into the required length. Generally, 50 square pipes per package are in stock with large specifications mostly in 10*10*0.8-1.5~~500*500*10-25, and square pipes are divided into structural square pipes, decorative square pipes, construction square pipes, mechanical square pipes, etc.

Square pipe is a hollow square cross-section of light thin-wall steel pipe, also known as steel cooling curved profile. It is made of Q235 hot rolled or cold rolled strip or coil as the base material by cold bending processing and then high frequency welding made of square section shape and size of the section steel. In addition to the thickening of the wall, the corner size and the flatness of the edge of the hot rolled special thick wall square pipe reach or even exceed the level of the resistance welding cold formed square pipe.

Hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery,exploration machinery and other manufacturing industries. Galvanized steel pipes are divided into hot-dip galvanized steel pipes and cold galvanized steel pipes. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the matrix of hot-dip galvanized steel pipe and the molten bath to form a compact zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel tube matrix, so its corrosion resistance is strong. Cold galvanized steel pipe is electric galvanized, galvanized amount is little, cold galvanized steel pipe galvanized layer is electroplating, zinc layer and steel pipe matrix independent stratification. Zinc layer is thin, zinc layer is simply attached to the steel tube matrix, easy to fall off. So its corrosion resistance is poor. It is prohibited to use cold galvanized steel pipes as water supply pipes in newly built houses.
