Hot-dip galvanizing is one of the most effective ways to protect steel from corrosion. But during fabrication, transportation, installation, or normal wear, galvanized coatings can get scratched, chipped, or otherwise damaged. When bare steel is exposed, corrosion can start fast—especially outdoors or in coastal, industrial, or wet environments.
That’s where Cold Galvanize comes in. It’s a zinc-rich coating designed specifically to repair damaged hot-dip galvanized surfaces in both the field and the shop, helping restore protection and extend the life of the part.
What Is Cold Galvanize?
Cold galvanize is a zinc-rich protective coating that can be applied directly to metal surfaces. Instead of sending parts back out for re-galvanizing, cold galvanize allows you to touch up and repair damaged areas quickly—right where the work is happening.
When properly applied, zinc-rich coatings help provide corrosion protection by creating a barrier and offering sacrificial protection, meaning the zinc helps protect the underlying steel.
Why Cold Galvanize Is Ideal for Repairs
Field and shop repairs need to be fast, practical, and dependable. Cold galvanize is commonly used to repair:
- Scratches, chips, and abrasions on galvanized coatings
- Welded areas after fabrication
- Cut edges and drilled holes
- Installation damage from handling or fastening
- Ongoing maintenance touch-ups on exposed steel
Key Benefits
- Fast and convenient: Apply on-site without sending parts off for rework.
- Field or shop use: Useful for contractors, fabricators, and maintenance teams.
- Helps extend service life: Restores protection to exposed steel before rust spreads.
- Professional finish: Designed to blend well with galvanized surfaces for a consistent look.
Common Applications
Cold galvanize is a practical solution across many industries and job sites, including:
- Structural steel and exposed metal connections
- Fasteners, brackets, plates, and hardware
- Railings, fencing, gates, and guardrails
- Utility components and outdoor equipment
- Industrial facilities and maintenance departments
Best Practices for Better Results
As with any protective coating, surface preparation and proper application matter. For best performance:
- Remove dirt, grease, and loose rust before application
- Ensure the surface is dry and clean
- Apply according to the product directions for coverage and dry time
- Use cold galvanize for touch-ups and repairs where hot-dip galvanizing has been damaged
