Industries & Applications

Automobile manufacturing: used for body parts and interior parts such as doors, hoods, roofs, etc., due to its good formability and corrosion resistance, it can cope with complex shapes and long-term use requirements.
Household appliances: suitable for refrigerators, washing machines, microwave ovens and other home appliance housings, with smooth surface, easy to paint, and can resist corrosion in humid environments.
Construction industry: used for building materials such as roofs, walls, guardrails, etc., the galvanized layer provides long-lasting rust protection and is suitable for outdoor applications.
Electrical equipment housing: widely used in electrical equipment housings such as electrical cabinets and distribution boxes to ensure the safety and stability of the equipment during long-term operation.
Furniture manufacturing: can be used to make metal furniture frames or decorative parts, with excellent appearance and corrosion resistance, improving the durability and beauty of furniture.

Other Infomation

We have two surface qualities for you to choose from:

Grade A, which is a high-quality surface. If you are particularly picky about the appearance of the product, you can choose it.
Grade B is a general quality surface. If the appearance requirements are not so high, it can meet your needs.

We also provide different surface treatments. You can choose the appropriate treatment method according to your needs. If you are unable to make a decision, you can contact our experts for consultation.

P, which is a phosphating treatment, can make the steel more corrosion-resistant and have stronger adhesion.
PC, phosphating and chemical treatment together, the protection effect is even better.
C, chemical treatment, or passivation, to prevent steel from rusting or corrosion.
PCO, phosphating, chemical treatment and oiling, this durability is great.
CO, chemical treatment, or passivation, and oiling, the anti-rust effect is great.
PO, phosphating and oiling, double protection, let you feel more at ease.
O, which is oiling, to prevent temporary oxidation of steel, simple and practical.
S, coating sealing, if you want long-term protection, choose it.
U, untreated, you can play with it, treat it however you want.
