Different  from galvanized sheet

The difference between the steel sheet and aluminium zinc plate mainly lies in the coating, the surface of the galvanized sheet evenly distributed with a layer of zinc materials, the anode protection effect to the parent metal, that is to say, zinc material the use of alternative corrosion protection of the parent metal, only finished when all zinc corrosion damage to the inside of the parent metal.

Galvalume sheet metal the surface of the coating is composed of 55% aluminum, 43.5% of the zinc and small amounts of other elements, aluminum zinc plating coating under microscopic surface for honeycomb structure, composed of aluminum in the "honeycomb" containing zinc, in this case, aluminium zinc plating coating has anodic protection role, but on the other hand due to the shrinking of zinc content on the one hand, because of the zinc material by aluminum bag not the role of electrolysis anode protection so greatly reduced, so once the aluminium zinc plate is cut, the cut off the edge of the protection of basic loss was will soon be under the condition of corrosion, so the plating aluminium zinc plate should be cut less as far as possible, Once cut, apply anti-rust paint or zinc rich paint to protect the edge, so that the service life of the plate can be extended .
