Hot-dip galvanizing

Corrosion protection for steel structures and parts, by bonding layers of zinc to the surface.

Hot-dip galvanizing protects steel from corrosion by adhering layers of zinc to the surface. Our partner's galvanizing kettle handles parts up to 1.5 m wide by 3 m deep by 12.6 m long, and up to 5 tons.

Because the part is fully immersed in molten zinc, the coating reaches inside and outside surfaces, edges, and corners, and it bonds with the steel instead of sitting on top like paint. Where the coating is scratched, the surrounding zinc keeps protecting the exposed steel.

  • Width: 1.5 m
  • Depth: 3 m
  • Length: 12.6 m
  • Up to 5 tons per part

Norms & standards

ASTM A123

Zinc coatings on fabricated iron and steel products, such as structural shapes, plate, bar, and assemblies.

ISO 1461

International standard for hot-dip galvanized coatings on fabricated iron and steel articles.

NMX-H-004

Mexican standard for hot-dip zinc coatings on iron and steel products.

ASTM A385

Practice for providing high-quality zinc coatings, including how parts should be designed and prepared for galvanizing.

ASTM A780

Repair of damaged or uncoated areas of hot-dip galvanized coatings.

Fabricate and galvanize in one project

Parts fabricated by our partner shops can go straight to galvanizing, so you receive finished, corrosion-protected steel without managing a second supplier. Typical galvanized products include:

Common questions

What is the largest part you can galvanize?

Parts up to 1.5 m wide, 3 m deep, and 12.6 m long, weighing up to 5 tons.

Which standards does your galvanizing meet?

ASTM A123, ISO 1461, NMX-H-004, ASTM A385, and ASTM A780.

Can you fabricate the parts and galvanize them too?

Yes. Parts fabricated by our partner shops can go straight to galvanizing, so you receive finished, corrosion-protected steel from one project.

What happens if the galvanized coating is damaged?

Damaged or uncoated areas are repaired following ASTM A780.

Need more than a fabricator?

We can also help you establish your own manufacturing operation in Mexico.
