Steel, Aluminum or Zinc (AZ)

Produced by coating steel. Aluminum - zinc alloy containing aluminum, silicon, 1.5% and 55% zinc.
The hardness of steel, aluminum, zinc alloy coating that is typically used in two hardness of aluminum sink G550 - steel coated aluminum sink. By hot-dip process The tensile strength of 550 MPa yield strength of not less than ideal for forming a square with a curved aluminum sink G300 - steel coated aluminum sink. By hot-dip process The tensile strength of 300 MPa yield strength of not less than ideal for forming a square with a low arch. Corrosion protection systemAlloy coated steel Rustproof aluminum sink with two characteristics.
Aluminum help shield against corrosion caused by the reaction between air and steel and increase the heat resistance at high temperatures.
Zinc helps prevent Cutting edge corrosion and scratch the surface. The zinc compounds to create the cutting edges. The electrode reactions. And will devote themselves to prevent corrosion of the steel instead.
