Galvanized square steel pipe is a kind of hollow square section steel pipe with square section shape and size made of hot rolled or cold-rolled galvanized strip or galvanized coil after cold bending and forming, and then high-frequency welding, or galvanized square steel pipe made in advance by hot dip galvanizing.

Hot-dip galvanized steel pipes are widely used in the manufacturing industries of construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, shed construction, etc.

Characteristics of galvanized seamless pipe Light weight, easy to handle Because the galvanized seamless pipe itself is relatively light, the daily transportation and construction are very simple, which can save a lot of time and cost. Good corrosion resistance The corrosion resistance of seamless steel pipes is very good. They are resistant to acid, alkali, salt and atmospheric environment.

Hot dip galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating can be combined. Hot galvanizing refers to pickling the steel pipe first. In order to remove iron oxide on the steel pipe surface, after pickling, the steel pipe is cleaned in ammonium chloride or zinc chloride aqueous solution or mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip tank. Hot dip galvanizing has the advantages of even coating, strong adhesion and long service life.
