Product Description

Carbon steel materials generally need to undergo surface treatment, and there are many types of surface treatments. Generally, electroplating, oxidation, phosphating, and electroless zinc flake coating are commonly used. The surface treatment of DIN975 carbon steel teeth is usually galvanized passivated or untreated.

Zinc passivation is to oxidize the surface of the galvanized layer to form an inert passivation layer to avoid the natural oxidation of zinc in the air, improve the overall protective performance and improve the appearance quality of the coating. The galvanized layer itself is white and yellow, and the brightness is not high. It must be passivated to appear white or colored.

The performance grade of stainless steel tooth bar: A2-70, A4-70, usually made of stainless steel SUS304, SUS316.

Threaded bars are usually used for connecting parts in the construction industry, equipment installation, decoration, etc., such as: large supermarket ceilings, building wall fixings, etc.
