Since the galvanized square tube is galvanized on the square tube, the application range of the galvanized square tube is greatly expanded compared with the square tube. It is mainly used for curtain wall, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power brackets, steel structure engineering, power engineering, power plants, agriculture and chemical machinery, glass curtain walls, automobile chassis, airports, etc.
Galvanizing introduction
Zinc plating has stronger protection and strong corrosion resistance. The entire structure consists of zinc, forming a dense quaternary crystal that forms a barrier on the steel sheet, thus effectively preventing the penetration of corrosion factors. Corrosion resistance comes from the barrier function of zinc. When zinc is sacrificed for trimming, scratching, and scratching of the coating, zinc forms an insoluble oxide layer that acts as a barrier.
Generally speaking, the Bolt is used to connect two objects, usually through the smooth hole, which needs to be used together with the nut, and a single bolt does not work. The tools are usually spanners. The head is mostly hexagonal, generally larger. The carriage bolt is used in the groove. The square neck is stuck in the groove during the installation process, which can prevent the bolt from rotating. The carriage bolt can move in parallel in the groove. Because the head of the carriage bolt is round, there is no cross groove or inner hexagon, which can be used to assist the design of tools. In the actual connection process, it can also play the role of anti-theft.
