Double Cranked Hinges Stainless Steel

Stainless steel hyperbolic hinges are usually made of 304 or 316 stainless steel, and their core advantage is excellent environmental resistance. After passing the standard 96-hour neutral salt spray test, there is basically no red rust on the surface.

This allows it to easily cope with harsh environments that are humid, salty or chemical-containing, such as coastal facilities, food processing plants or chemical storage cabinets, ensuring that the hinges will not rust or fail for a long time, significantly reducing replacement and maintenance costs due to corrosion.

Thanks to the high strength of stainless steel and the mechanical optimization of the hyperbolic structure, this type of hinge can withstand loads far exceeding those of ordinary hinges. The dynamic load-bearing capacity of a single hinge usually reaches 50 to 80 kg.

This strong support force can effectively prevent heavy door leaves (such as large equipment access doors and heavy fire doors) from sagging or deforming during use, ensuring that the door body maintains precise alignment and smooth opening and closing all year round.

The unique "double bend" structure of the hyperbolic hinge allows it to work smoothly even when the door frame and door leaf are not on the same plane. The offset distance they are designed to compensate for is typically 10 to 25 mm.

This feature is extremely valuable when installed on doors with decorative panels, sealing strips or non-standard frames. It can achieve perfect installation without complex modifications to the cabinet, solving common installation and adaptation problems.

With precise bending radius and gap control, the hyperbolic structure creates a safe transition zone between door leaf and frame. The running gap between its movable parts is usually designed to be greater than 15 mm, which effectively prevents the risk of fingers being accidentally pinched.

It fully complies with the internationally accepted design specifications for children's safety products and is especially suitable for schools, kindergartens and home environments.

• Made of 304 stainless steel, it has passed the 96-hour salt spray test, is suitable for humid and chemical environments, and will not rust after long-term use.

• A single hinge can bear a load of 50-80 kilograms, ensuring that heavy door leaves do not sag and maintain precise alignment of the door body.

• The double-curved structure compensates for offsets of 10-25 mm and easily copes with door frames with decorative panels or sealing strips.

• The shear resistance of key parts exceeds 1500 N and can withstand impact. It is suitable for warehouses, outdoor and other security places.
