Galvanized steel strip is processed by ordinary steel strip pickling, galvanizing, packaging and other processes. It is widely used because of its good anti-corrosion performance. It is mainly used to make metal products that are cold-worked and no longer galvanized. For example: metal products such as light steel keel, fence net peach-shaped column, sink, rolling shutter door, bridge frame.

Processing household appliances, such as sinks, etc., can strengthen door panels, etc., or strengthen kitchen utensils.

Light steel keel, roof, ceiling, wall, water retaining board, rain cover, rolling shutter door, warehouse inner and outer panels, insulation pipe shell.Reinforcement and protection in household appliances such as refrigerators, washing machines, showers, and vacuum cleaners

Automobile industry Cars, trucks, trailers, luggage carts, refrigerated truck parts, garage doors, wipers, fenders, fuel tanks, water tanks, etc.

passivation

The galvanized layer is passivated to reduce folding corrosion (white rust) under tidal temperature storage and transportation conditions. However, the anti-corrosion performance of this chemical treatment is limited and, moreover, hinders the adhesion of most paints. This kind of treatment is generally not used in the zinc-iron alloy coating. In addition to smoothing the surface, as a routine, the production plant oils.

Oiling can reduce steel plate corrosion under wet storage and transportation conditions, and re-oiling steel plates and steel strips after passivation treatment will further reduce corrosion under wet storage conditions. The oil layer should be able to be removed with a degreasing agent that does not damage the zinc layer.
