Commercial Chainis generally made from low-carbon steel or stainless steel and produced according to ASTM and ISO standards for dimensional consistency and tensile strength. It is designed for light to medium-duty applications where high precision or certified lifting performance is not required. Surface finishes such as zinc plating or galvanization provide corrosion resistance and extended service life. With moderate strength and good flexibility, Commercial Chain is widely used in agriculture, marine, fencing, and general-purpose binding or securing tasks. Its cost-effectiveness, durability, and versatility make it suitable for both indoor and outdoor environments.
