Pro-Tech Ced Coating

Rod Metal Spring CED Coating Service is an advanced anti-corrosion process widely used for springs to provide a durable, uniform, and rust-resistant finish. Springs, being dynamic components exposed to constant stress and environmental conditions, require reliable protection without affecting their mechanical properties.

Our CED coating process ensures that each spring is thoroughly cleaned, pretreated, and uniformly coated using a cathodic epoxy-based paint. The coating reaches even the innermost coils and complex shapes, offering superior edge coverage and complete surface protection.

The coated springs are then oven-cured to form a hard, smooth, black film that is both corrosion-resistant and flexible. This makes CED coating ideal for automotive suspension springs, industrial compression springs, and other critical applications where performance and longevity are essential.
