Anti-rust treatment of galvanized sheet.

Anti-rust strengthening measures of galvanized sheet itself Increase the thickness of zinc coating:

the thicker the coating, the longer the corrosion resistance life, especially suitable for wet or industrial atmospheric environment.

Adopt high-quality galvanizing process: for example, hot dip galvanizing (GI) is thicker and more durable than electro-galvanizing; Alloying zinc plating (such as zinc-iron alloy) can improve weather resistance.

Post-processing enhancement: Passivation treatment: dense chromate or chromium-free passivation film is formed, which significantly inhibits the generation of white rust. Oil coating or paint sealing: lightly coat antirust oil or fingerprint resistant coating, and temporarily protect the storage and transportation stage.
