What are the characteristics of galvanized sheet?

2022-05-05

The surface of the galvanized steel sheet has a unique smooth, flat and gorgeous star flower, and the base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the galvanized sheet can reach 25a, the heat resistance is very good, and it can be used in a high temperature environment of 315 ° C; the adhesion between the coating and the paint film is good, and it has good processing performance, which can be punched, sheared, welded, etc.; The surface conductivity is very good.

Now this product is more and more widely used, precisely because it has the following characteristics:
(1) Heat reflectivity:
The thermal reflectivity of galvanized steel sheet is very high, twice that of galvanized steel sheet, and people often use it as a thermal insulation material.
(2) Heat resistance:
Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperature of more than 300 degrees Celsius, which is very similar to high-temperature oxidation resistance of aluminized steel plate. Corrosion resistance:
The corrosion resistance of galvanized steel coil is mainly because of aluminum, the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
(3) Economical:
Because the density of 55%AL-Zn is lower than that of Zn, the area of the galvanized steel sheet is more than 3% larger than that of the galvanized steel sheet under the same weight and the same thickness of the gold-plated layer.
(4) The galvanized steel sheet has a gorgeous silver-white surface.
(5) Galvanized steel sheet and galvanized steel sheet have similar processing performance and spraying performance.
(6) Easy to paint

The galvanized sheet product of the galvanized sheet manufacturer has excellent adhesion between the paint and the paint. It can be painted without pretreatment and weathering treatment, and can also be directly coated on advertising boards and general-purpose boards.
