Extremely Corrosion Resistance

The chromate conversion coating treatment creates a dense protective layer. It typically withstands salt spray testing for 72-120 hours or more, making it less susceptible to the formation of white rust (zinc oxide).

More Beautiful, Upscale Appearance and Texture

The surface exhibits a iridescent, slightly yellow-green hue, creating a vibrant and textured look, adding a more upscale and professional appearance.

Better coating adhesion and wear resistance.

The chromate coating provides a stronger bond with the zinc layer, offering greater wear resistance. It also protects the underlying metal from friction and scratches during transportation and installation.

Modern processes are more environmentally friendly (trivalent chromium).

Modern zinc coating processes generally use trivalent chromium passivation, which is non-toxic and environmentally friendly. It complies with stringent environmental regulations such as EU RoHS and REACH, and can be exported to European and American markets.
