Galvanized pipe Hot diped , Electroplating diped
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.
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.
01. SMOOTHNESS
No composite indentation, no residual stress, no deformation after shearing.
Characteristics:Weather proof; heating insulation; fireproof; anti-rust; sound insulation; long life span: more than 20 years.
Corrosion Resistance: the aluzinc coating surface protects the base steel not only by providing barrier to corrosion elements, but
also by the sacrificial nature of the coating.

I-beam, also known as steel beam (English name universal Beam), is a long steel with the section of the I-shaped. I-section steel is divided into hot rolIed I-beam and lightweight I-beam
H-beam is a kind of Economic section steel, which sectional area distribution is more optimized, the ratio of strength to weight is more reasonable, Mechanical properties of section is more better.It is developed from the I-section steel optimization of a better section mechanical properties of the economic section steel, because its section is same as the English letter "H" ,so be named as H-Beam. Because the various part of H-beam is arranged at right angles, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, so it has been widely used.
