Three Materials for Your Choose From
At Tuohai, you can choose lock link chain in a material that suits your chainwheel or equipment and your budget. Our three standard material options let you balance corrosion resistance, durability and appearance for your application.
A widely used material that balances strength and cost for your everyday valve chainwheel and manual door applications.
Available in 304 and 316 stainless steel, with corrosion resistance and a clean metal appearance for your damp-environment chainwheel installations.
Solid brass throughout, combining a natural golden appearance with corrosion resistance for your valve operating chain.
Different Surface Treatment for Your Environment
Tuohai offers a choice of finishes to give your lock link chain the surface protection and appearance you want. From zinc plating to e-coating, we can match the finish to your equipment and working environment.
Zinc Plated Lock Link ChainA bright, neat finish that combines corrosion protection and appearance for indoor chainwheel applications.
Hot-Dip Galvanized Lock Link ChainA thicker zinc coating than standard zinc plating, offering corrosion protection for outdoor and damp-environment chainwheel applications.
