DETAILS DESCRIPTION
Surface treatment methods for lifting chains: In a dry, clean indoor environment: If the budget is very limited and rust prevention requirements are not high, blackening or electroplating zinc can be considered, but their limitations should be noted. Electroplating zinc is slightly better than blackening. For special requirements (such as high corrosion resistance, high-temperature resistance, specific color identification) with sufficient budget: Dacar coating can be considered. High-strength chains: Regardless of the surface treatment used, G80/G100 grade chains must undergo carburizing quenching and other heat treatments to ensure strength, with surface treatment being an additional protective layer. When choosing a surface treatment, it is essential to fully consider the actual working environment of the chain (humidity, corrosive medium, temperature, degree of wear) and the requirements for service life, selecting the appropriate protection method. The initial cost saved by sacrificing corrosion resistance often leads to higher replacement costs and safety risks due to premature corrosion failure of the chain.
