Galvanized Steel Hinges
Weight Range ： 0.5g–500kg
Length: 10- 3000 mm
Galvanized steel hinges offer superior rust protection through a strong zinc layer on the surface. This layer of protection can effectively isolate moisture and corrosive substances in the air, allowing the product to remain intact for a long time even in high-humidity bathrooms or coastal areas. High-quality hot-dip galvanized hinges can pass more than 72 hours of neutral salt spray testing without producing red rust, and their anti-rust capabilities are several times that of ordinary products. At the same time, this type of hinge has excellent load-bearing performance. A standard 150 mm hinge can safely bear a weight of more than 50 kilograms, fully meeting the needs of various heavy-duty doors.
Its excellent durability allows the product to maintain a long service life of 10-20 years under normal use conditions, significantly reducing maintenance costs caused by replacing accessories. The surface hardness of the galvanized layer reaches 250-300 Vickers hardness, which makes it effectively resistant to scratches and collisions during installation and use, keeping the appearance as new as ever. In terms of fire safety, the non-combustible nature of steel allows it to maintain structural integrity in environments up to 1370 degrees Celsius, providing valuable extra time for emergency evacuation in a sudden fire.

Specification
Benefits
Excellent corrosion resistance
Galvanized steel hinges offer excellent rust resistance. The zinc layer acts like a barrier against moisture and corrosion.
Even if the surface is scratched, zinc will corrode preferentially to protect the inner steel.
High-quality products pass the 72-96 hour salt spray test and will not rust. Its lifespan is several times longer than ordinary hinges outdoors.
Strong, durable and load-bearing
This hinge construction is very strong. The steel itself is strong and the galvanized coating also adds to the overall durability.
It can withstand a lot of pressure and frequent switching. A standard 150mm hinge can bear more than 50kg. Ideal for heavy-duty gates and high-usage situations.
High surface hardness and damage resistance
The zinc layer is firmly bonded to the steel and the surface is very hard. This effectively resists scratches and collisions during installation and use.
Its hardness value can reach 250-300 Vickers hardness. This is far more resistant to wear and tear than a regular paint coating. This ensures that the product remains intact before and after installation.
Excellent fire protection
It is a safe fireproof component. Steel does not burn and has a melting point as high as approximately 1370°C. The surface zinc layer can also withstand high temperatures of 419.5°C.
It can keep the supporting structure from failing in the early stage of fire. Buy valuable time for safe evacuation and comply with building fire protection regulations.
