Tapered Strap Hinge
Dimensional Tolerance : ±0.05mm
Salt Spray Test ： ≥ 96 hours
Surface Roughness ： Ra ≤ 0.8 µm
Certifications ： DIN 1.4301、DIN 1.4401
Tapered strap hinge provides excellent performance and reliability with its unique structural design. The blade thickness of the hinge is greater than or equal to 1 mm, and the width specification covers more than 50 mm to ensure that it has sufficient strength and load capacity. The precise manufacturing process strictly controls the key dimensional tolerances to within plus or minus 0.05 mm, which ensures perfect fit during installation and a smooth and silent operation experience. Whether it is used for heavy industrial doors or cabinet equipment that requires frequent opening and closing, it provides solid and stable support.
The hinge hinge's excellent surface finish and long-lasting corrosion resistance further demonstrate its outstanding performance. To ensure it can withstand extreme environments such as moisture and salt spray, each hinge has undergone rigorous neutral salt spray testing and is resistant to rust for at least 96 hours. In addition, the surface is smooth and easy to clean due to its surface roughness less than 0.8 microns. Our production system strictly follows strict German industrial standards. From material selection to final inspection, the products we deliver to our customers are reliable and durable, because each step reflects strict control of quality.

Applications
Industrial heavy gate
In a warehouse or factory, heavy-duty steel doors require strong and durable support. The tapered belt hinge is made to effectively carry the door weight because of its thicker roots.
For example, an industrial door weighing more than 500 kg usually needs to be equipped with a hinge with a blade thickness of no less than 5 mm to ensure that it will not deform or sag during long-term use and ensure smooth switches.
Outdoor anticorrosion wood wall door
Long, rust-proof hinges are required when connecting wooden doors with stone or metal door posts. A conical hinge made of 316 stainless steel and passed the 96-hour salt spray test is ideal.
Its length can be customized according to the thickness of the door panel, such as 400 mm, which can not only disperse the load to protect the wooden door, but also resist rainwater erosion and extend the overall life.
