Small and uniform spangle 1.Color is bright silver 2.High surface hardness (scratch is not easy to rub) 3.A plurality of colors may be applied a semipermeable membrane
Galvalume when used as a tablet or other purposes by spray coating, degreasing simply without
the need for pre-treatment or etching treatment, because of its coating and the coating has a
good combination of polarity, and hot-dip galvanizing layerIt is not.
Relatively light weight
Because of galvanized steel plating lighter, in the case of the same coating thickness is greater
than the developed area per ton of galvanized steel, with 0.48MM, plating 40μm (both sides),
for example, its weight and tons of steel per square expand area as follows: Weight per square meter per ton of steel to expand the area Substrate thickness AZ150 Z275 AZ150 Z275 0.48mm 3.94kg 4.06kg 254m2 246m2
Corrosion mechanism of Galvanized Steel Sheet
(1) physical effects Aluminum zinc coating on the surface of steel sheet, steel plate in contact with the outside blocking
the corrosive medium, the steel sheet eliminating the corrosive effects of corrosive media.
(2) chemical action Corrosion beginning, zinc portion preferential dissolution (~ -1.05V), followed by aluminum-rich partially
dissolved (-0.9V), between last metal compound is dissolved (-0.75V), are lower than the electrode
potential of iron (-0.44V) Therefore aluminum zinc layer protects the substrate etching priority, called a
sacrificial anode protection.
(3) trivalent aluminum ion doped role Polarization resistance Rp (Al-Zn) = 10.5kΩ * cm2 Rp (Zn) = 3.1kΩ * cm2 Thus slowing the corrosion reaction speed
