The hot-dip galvanized square tube is a square tube formed by a series of chemical reaction in a hot-dip galvanizing bath by a square tube formed by welding a steel plate or a steel strip after being crimped; or may be cold-rolled through a hot-rolled or cold-rolled galvanized steel strip. A hollow square section steel tube bent and then welded at a high frequency. The production process of the tube is simple, the production efficiency is high, the variety specifications are large, and the equipment is small, but the general strength is lower than the seamless square tube.
Hot-dip galvanized square tube 50*50*5*6m, expressed as: 50 (width) * 50 (width) * 5 (wall thickness) * 6 m (meters). Because the square tube is equilateral, the commonly used meter is 6 meters; the general industry is simply expressed as: 50*5 square. According to the representation method of the square tube, the square tube generally has the side width and the wall thickness as the representation standard.
The hot-dip galvanized square tube has good strength, toughness, plasticity and welding and has good ductility. The alloy layer and the steel base are firmly attached, so the hot-dip galvanized square tube can be cold-drawn, rolled and drawn. , bending and other molding without damaging the coating; suitable for general processing such as drilling, cutting, welding, cold bending and other processes. The surface of the hot-dip galvanized parts is bright and beautiful, and can be directly used for engineering according to requirements.
