Hot-dip galvanising consists of a coating process that protects metal surfaces from corrosion, providing protection that lasts more than 25 years in most atmospheres.
The parts that are going to be galvanised are cleaned of grease (degreased) and rust (stripped), and are placed in a bath of molten zinc at 450ºC. During the immersion a chemical-metal reaction occurs between the iron and the zinc, with a variety of iron-zinc alloy layers and an exterior layer of pure zinc.
10 advantages of galvanising:
- 1. Long-lasting
- 2. No need for maintenance
- 3. Economical
- 4. Versatile
- 5. Reliable
- 6. Coating tenacity
- 7. Integral coating
- 8. Triple protection
- 9. Easy to weld
- 10. Easy to paint
Our 15,000 m2 facilities have:
- A ceramic crucible of 2,500 x 1,000 x 1,260 mm
- A steel crucible of 12,500 x 2,600 x 3,600 mm
Centrifuge galvanizing process
Small parts are galvanized placed in perforated metal baskets, which are introduced into the zinc bath at temperatures up to 560°C and then subjected to centrifugation for final drained.
Temperature, immersion time and spin speed and duration can be adjusted automatically and individually for each product.
The process is similar to hot dip galvanizing for large or normal parts.
