Chrome-Free Passivated Light Steel Keel

Nowadays, light steel keel is widely used in all aspects of home decoration ceiling, office partition, engineering construction, the quality of light steel keel plays a vital role in building safety.

Now there are many kinds of keel on the market, different construction needs for different light steel keel styles, with the improvement of the public standard of living, more and more the pursuit of harmless, environmental protection, high quality construction materials.

What Is Chrome-Free Passivation?

We all know that the main material of light steel keel is galvanized steel, and zinc is a relatively active chemical nature of the metal, with the passage of time, the galvanized coating will soon become dark and white corrosion, in order to slow down the occurrence of this situation, generally will be in the galvanized material for passivation treatment, in order to enhance the durability of the keel.

In the traditional passivation process, “chromates” are used, of which “hexavalent chromium” is a carcinogen that is a serious hazard to humans.

ANSHIDADI Chromium-free passivation layer of high quality and environmental protection, in line with the EU RoH directive on metal lead, chromium restrictions on the requirements of the production, the process of Cr6 + ions.

Adopting advanced galvanization process, with more excellent corrosion resistance, solid materials, durable and solid.

Exquisite craftsmanship, strong and firm snaps, strong load-bearing, to ensure the stability and safety of the construction. Beautiful appearance, showing noble character.

An’s chrome-free passivated light steel keel, to create a livable space, to create a healthier, safer and more comfortable environment for people.
