Hot dip galvanized square tube is a square tube formed by a series of chemical reactions in a hot dip galvanized pool, which is welded after being rolled and formed from steel plate or strip; A hollow square section steel pipe can also be formed by hot rolling or cold rolling galvanized steel strip, cold bending, and then high-frequency welding. The production process of pipes is simple, with high production efficiency, multiple varieties and specifications, and less equipment investment, but the general strength is lower than that of seamless square pipes.
Representation method
Example: A square tube of 50 * 50 * 5 * 6m is represented as 50 (width) * 50 (width) * 5 (wall thickness) * 6m (meters). Because the square tube is equilateral, the commonly used meter count is 6 meters; The general industry is simply represented as: 50 * 5 square meters. According to the representation method of square tubes, they are generally represented by edge width and wall thickness.
performance
Hot dip galvanized square pipes have good strength, toughness, plasticity, welding and other process properties, as well as good ductility. Their alloy layer adheres firmly to the steel base, so hot dip galvanized square pipes can be formed through various processes such as cold stamping, rolling, wire drawing, bending, etc. without damaging the coating; Suitable for general machining processes such as drilling, cutting, welding, cold bending, etc. The surface of the hot-dip galvanized parts is bright and beautiful, and can be directly used in engineering according to needs.
classification
Hot dip galvanized square pipes can be divided into seamless and welded joints, and seamless square pipes are formed by extruding seamless circular pipes.
texture of material
Ordinary carbon Q235 (A, B); Low alloy Q345 (A, B)
purpose
Hot dip galvanized square pipes, due to their excellent performance, have been widely used in glass curtain walls, power towers, communication grids, water and gas transmission, wire sleeves, houses, bridges, metal structures, power transmission, and other fields in recent years.
