Repairing Scratches on Galvanized Cable Trays

Thoroughly wire brush the affected area and apply sufficient coats of zinc rich paint (by brush or aerosol spray) to give a coating thickness in accordance with supply standard e. Zinc-rich paint is cost-effective and easy to use, making it ideal for small, localized defects. It restores corrosion resistance by forming a sacrificial zinc layer. However, its longevity is slightly less than other methods in aggressive environments. Common mechanical problems include: Sagging and Deflection: Excessive bending occurs when trays carry loads beyond their designed capacity or when support intervals are. Small areas of the coating may be damaged by operations such as cutting or welding after galvani...
