The most widely used and cost-effective way to achieve reliable corrosion protection is galvanizing. It is designed to protect against corrosion and at the same time has a decorative character. Galvanizing is suitable for steel, alloy, brass and copper. The galvanized surface is soft and tough, it is used as a decorative coating with good corrosion resistance or as a base for organic coatings.
