Galvanized Channel Beam

Product Description

Hot-dip galvanized steel, according to the different galvanizing process can be divided into hot-dip zinc channel and hot-dip galvanized steel, is the rust after the steel immersed in 440 ~ 460 ℃ melting zinc solution, the steel Component surface attached to the zinc layer, which play the purpose of corrosion.

Advantage:
(1) a thick, dense zinc layer covering the surface of steel, it can avoid the steel matrix and any contact with the corrosion solution to protect the steel matrix from corrosion. In the general atmosphere, the surface of the zinc layer to form a layer of thin and dense zinc oxide surface, it is difficult to dissolve in water, so the steel matrix plays a protective role. If zinc oxide and other components of the atmosphere to produce insoluble zinc salt, the anti-corrosion effect is more desirable.
(2) with iron - zinc alloy layer, combined with dense, in the marine atmosphere and atmospheric atmosphere of the performance of the unique anti - corrosion;
(3) due to the combination of solid, zinc - iron miscible, with a strong wear resistance;
(4) Since zinc has good ductility, its alloy layer and steel base attached to a solid, so hot-rolled parts can be cold, rolling, drawing, bending and other molding without damage to the coating;
(5) hot-dip galvanized steel structure, the equivalent of an annealing treatment, can effectively improve the mechanical properties of steel matrix to eliminate the steel forming welding stress, is conducive to the steel structure for turning.
(6) hot galvanized after the surface of the bright and beautiful.
(7) pure zinc layer is the most hot galvanized galvanized layer of galvanized layer, its nature is basically close to pure zinc, with ductility, so it is full of flexibility.

Application Scope

The application of hot-dip galvanized steel is also expanding with the development of industry and agriculture. (Such as: glass curtain wall, power tower, communication grid, water and gas transportation, wire casing, scaffolding, housing, etc.), bridges, transportation; industry (such as chemical equipment, oil processing, marine exploration , Metal structure, power transmission, shipbuilding, etc.); agriculture (such as: irrigation, heating room), and so on, in recent years has been widely used. As the hot-dip galvanized products with beautiful appearance, good corrosion resistance and other characteristics, its wide range of applications.
