Product parameters
Galvanized steel plate is a steel plate with a layer of zinc plated on the surface. Galvanizing is an economical and effective anti-corrosion method that is often used. About half of the world's zinc production is used in this process. Galvanized steel plate is to prevent corrosion on the surface of the steel plate to extend its service life, coated with a layer of metal zinc on the surface of the steel plate, the zinc-coated steel plate is called galvanized plate.
The steel parts after rust removal are immersed in about 500 melted zinc liquid, so that the surface of the steel members are attached to the zinc layer, so as to play the purpose of anti-corrosion. Hot dip galvanized steel springboard has the advantages of strong adhesion and long service life. Its pattern into lentil shape, diamond shape, round bean shape, oval mixed shape, the market with lentil shape is more common.
The galvanized layer column is marked with the words Z80, Z90, Z100, Z120Z, Z275, etc., and the thickness of the galvanized layer is indicated by the factory label. These are all made by the steel mill when it leaves the factory, with high credibility.
The correspondence between the G and Z labels is as follows:
G40——Z120 G50——Z150 G60——Z180 G65——Z200 G70——Z215 G75——Z230 G90 ——Z275
The density of zinc is 7.14 g /cm3; So 275/7.14=38.5154cm3=38515.4mm3, that is, the average thickness per square meter is 38.5154 microns. Two sides are half of it.
The weight of 1 micron zinc plated per 1㎡ is 7.1g, 275g/7.1≈31 microns (average thickness).
