PRODUCT DESCRIPTION
The galvanized square tube is galvanized on the square tube, so the application range of the galvanized square tube has been greatly expanded compared with the square tube. Divided into alloy galvanized square tube and non-alloy galvanized square tube, most of the market is alloy galvanized square tube. Mainly used in curtain wall, construction, machinery manufacturing, steel structure engineering, shipbuilding, solar power generation support, steel structure engineering, electric power engineering, power plant, agricultural chemical machinery, glass curtain wall, automobile chassis, airport, etc.
Galvanized square pipes for construction have stronger protection and stronger corrosion resistance. The entire structure is composed of zinc, which forms dense quaternary ammonium salt crystals and forms a barrier on the Steel Plate, thereby effectively preventing the penetration of corrosion factors. Corrosion resistance is due to the strong protective function of the zinc barrier. When zinc is used for sacrificial protection of cut edges, scratches and coating scratches, zinc forms an insoluble oxide layer that acts as a barrier protection
Square tube material classification
Square tubes are divided into plain Carbon Steel square tubes and low alloy square tubes according to their materials. Ordinary carbon steel is divided into Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc.; low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.
Square rectangular tubes are divided into hot-rolled seamless square steel tubes, cold-drawn seamless square tubes, extruded seamless square tubes and welded square tubes according to the production process. Welded square tubes are divided into: 1. Arc welded square tubes, resistance welded square tubes (high frequency, low frequency), gas welded square tubes, furnace welded square tubes; 2. Straight seam welded square tubes and spiral welded square tubes are divided according to welding points
Classification of Sectional Shapes of Rectangular Tubes
Square tubes are classified according to cross-sectional shape: (1) Square tubes with simple cross-sections - square square tubes, rectangular square tubes (2) Square tubes with complex cross-sections - flower-shaped square tubes, open-shaped square tubes, corrugated square tubes, special-shaped square tubes Tube
