ULTRA WPTM chain features a coating that resists corrosion in fresh or salt-water environments. The patented mechanical-plating process that produces this coating creates a metallurgical bond so the plating will not flake or peel off. All surfaces are coated prior to assembly, providing protection against corrosion. This coating provides freedom from hydrogen embrittlement.
