Product Features

1. High strength performance: The minimum breaking force of the G80 chain is 4 times its rated working load, and the test load is 2 times the rated load, which can effectively ensure the safety of lifting operations. For example, a G80 chain with a rated load of 5 tons can have a minimum breaking force of 20 tons.

2. High quality materials and processes: Usually made of high-quality alloy steel materials such as manganese steel, and subjected to strict heat treatment processes such as quenching and tempering to improve the strength, toughness, and wear resistance of the chain.

3. Strict quality control: During the production process, it is necessary to strictly follow the requirements of NACM standards and test the dimensional tolerances, breaking force, hardness and other indicators of the chain to ensure stable and reliable product quality.

4. Diversified surface treatment: Polishing, blackening, galvanizing, spraying and other surface treatment methods can be selected according to different usage environments and needs to improve the corrosion resistance and appearance quality of the chain.
