large stock ASTM A36 50x50 Hot Dip gi square pipe Galvanized Coating Hollow Section shs rhs 40x80 Rectangular pipe

Galvanizing can increase the corrosion resistance of steel pipe and prolong its service life.Galvanized pipe USES is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube, etc.Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.The complex physical and chemical reactions between the matrix of hot dip galvanized steel tube and the molten bath result in the formation of a tight and corrosion-resistant zinc-ferroalloy layer.
