ASTM A780 is the international reference standard for repairing galvanized coatings damaged by cuts, welds, impacts, or corrosion. GALVANOL, with 96% zinc in the dry film, meets its requirements.
Methods permitted by ASTM A780
- Zinc-rich paints with a high zinc content in the dry film. This is the most practical method.
- Zinc alloy welding applied with heat to the damaged area.
- Metallizing (thermal spray zinc).
Why GALVANOL complies
- 96% zinc in the dry film, with 99% pure zinc (ISO 3549).
- Easy to apply in a can, bucket, or spray, even in hard-to-reach areas.
- Good adhesion on damaged galvanized surfaces and properly prepared bare steel.
- Tested for aggressive environments according to ISO 12944 (up to C5).
Typical uses
- Railings, bridges, towers, and galvanized structures.
- Pipes, tanks, and industrial installations.
- Cuts, scratches, and impacts on galvanized surfaces.
- Welding-affected zones. See how to repair welds step by step.
In Europe, the equivalent reference is ISO 1461. See GALVANOL and ISO 1461.
