Steel Piano Hinges Heavy Duty
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
Steel piano hinges heavy duty is the ultimate solution for high loads and harsh environments. Its core uses high-strength steel strips with a thickness of 3 to 4.5 mm, ensuring that a single meter length can carry a weight of more than 100 kilograms, fundamentally preventing the door leaf from sagging. In addition, through processes such as hot-dip galvanizing, it can easily pass more than 500 hours of salt spray testing, without fear of long-term corrosion in humid, industrial or coastal environments.
The outstanding performance of this hinge is also reflected in its precision construction and long life. High-end models have built-in ball bearings, allowing them to be opened and closed more than 100,000 times while still being smooth and silent even under full load. Its continuous and integrated design evenly distributes the load, increasing the lateral tensile strength of the connection parts by more than 25%, significantly enhancing the impact resistance and safety redundancy of the overall structure.

Specification
Advantages
Top rustproof
It is hot dipped galvanized or high quality powder coated. These processes provide extremely strong protection against rust. Its salt spray test time exceeds 500 hours.
This means it can withstand industrial pollution or seaside salt spray. In harsh environments, it remains corrosion-free for decades. Always looks and functions as good as new.
Easy to install
This is a one-piece structure. No need to repeatedly align during installation. Just align the door and door frame. The screw holes are pre-drilled and spaced 100 to 150 mm apart.
Installation can be completed quickly by one person. Even a 2-meter-long gate can be easily handled. The installation efficiency is high and the force is evenly distributed.
Widely adaptable
The products provide a wide range of specifications to choose from. Width from 25mm to 100mm, more than 5 kinds. There are also at least 3 categories of mainstream options for surface treatment.
Whether it is concealed installation or industrial style design, it can be matched. This saves the time and cost of customization. Designers can quickly find the right model.
High security
A continuous hinge acts like a strong metal ligament. It can firmly connect the door and frame into one. Tests show that its transverse tensile strength can be increased by more than 25%.
This significantly increases resistance to shock and vibration. During storage or transportation, it can effectively prevent the door from falling off accidentally. Safety redundancy is greatly improved.
why choose us
-
★ Strong anti-rust
Adopting advanced processes such as hot-dip galvanizing. Corrosion resistance is significantly enhanced. Can pass salt spray test for up to 500 hours. Perfectly suited to humid, industrial or coastal environments. Maintain appearance and performance over time.
