Carbon steel materials generally need surface treatment. There are many kinds of surface treatment, such as electroplating, oxidation, phosphating, non electrolytic zinc coating, etc. The surface treatment of din976 carbon steel is usually galvanized passivation or no treatment.
Galvanizing passivation is to form an inert passivation layer on the surface of zinc coating, which can avoid the natural oxidation of zinc in the air, improve the overall protection performance and improve the appearance quality of the coating. Zinc coating itself is white yellow, brightness is not high, must be passivated to appear white or color.
Din976 teeth are usually used in construction industry, equipment installation, decoration and other connectors, such as: large supermarket ceiling, building wall fixation, etc.
