The galvanized square pipe is a hollow square section steel pipe with a square section shape and size made of hot-rolled or cold-rolled galvanized steel strip or galvanized coil as a blank, cold-bent, and formed by high-frequency welding. , Or a galvanized rectangular tube made of cold-formed hollow steel pipe prepared in advance and then processed by hot-dip galvanizing.
Galvanizing has a stronger protective effect and strong corrosion resistance. The entire structure is made of zinc to form a dense quaternary crystal, which forms a barrier on the steel plate, thus effectively preventing corrosion factors from penetrating. The corrosion resistance comes from the strong protective function of the barrier layer of zinc. When zinc is used for sacrificial protection on the cut edges, scratches and scratches of the coating, the zinc forms an insoluble oxide layer and exerts a barrier protection function.
Steel pipes are hard, can withstand external forces and weather impacts very well, so they have a long life.
The weight of steel pipes is light, due to the properties of steel and the characteristics of hollow, thin-walled steel pipes, so they are easy to transport and construct at construction sites.
The galvanized coating on the outside of steel pipes helps them increase their resistance to physical and chemical agents such as corrosion and oxidation, helping to prevent the formation of rust layers on the surface of steel pipes, ensuring durability and high aesthetic.
The product is completely manufactured and galvanized, so it saves installation time, does not require painting or processing, the product is still beautiful.
Since the galvanized square tube is galvanized on the square tube, the application range of the galvanized square tube has been greatly expanded compared to the square tube. It is mainly used in curtain walls, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, etc.
Regular spangle, minimal spangle, zero spangle, big spangle surface will be offered according to requriment.
Zhencang Steel produce all kinds of galvanized pipes, hot rolling and cold rolling. In order to satisfies the market demands we adopt latest new technical to ensure high quality steel products.
