Galvalume Steel Plate
The surface of the galvalume steel plate has a unique smooth, flat and gorgeous star flower, and the base color is silver-white.
The special coating structure gives it excellent corrosion resistance.
The normal service life of galvalume sheet can reach 25 years. It has good heat resistance and can be used in high temperature environments of 315°C.
The coating has good adhesion to the paint film and has good processing performance, and can be stamped, sheared, welded, etc.;
Surface conductivity is very good.
Description:
Galvalume-coated steel plate is an alloy-coated steel plate widely used in many fields such as building materials, home appliances, automobiles, environment, machinery, and ships.
Galvalume steel plate is covered with aluminum-zinc alloy on the surface of the steel plate.
It is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600℃.
Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense An alloy-coated steel plate with quaternary crystals.
Property & Specification
Corrosion resistance
The corrosion resistance of "galvalume steel coil" is mainly due to the protective function of aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
Heat reflectivity
The heat reflectivity of galvalume steel sheet is very high, twice that of galvalume steel sheet. People often use it as heat insulation material.
Economy
Because the density of 55% AL-Zn is smaller than that of Zn, when the weight is the same and the thickness of the gold plating layer is the same, the area of the galvalume steel sheet is more than 3% larger than that of the galvalume steel sheet.
