Use either Zinc Phosphate or Cold Galvanizing on steel and iron surfaces, especially at welded joints, to protect from corrosion. These corrosive barriers conatin a high 95% concentration of zinc for maximum resistance against solvents and abrasions.
• Cold Galvanize provides a quick, inexpensive coating (think zinc paint) that can be applied on ferrous metals to help prevent rust. However, it can't match the effectiveness of true hot-dip galvanizing which is a chemical bonding between the zinc and the underlying steel, and not just a coating
• Zinc Phosphate has great anti-corrosion and adhsesion properties
