7. Conclusion

The galvanizing industry is constantly evolving in terms of technology, quality and quantity, due to three factors:

more diversified and more technical market demands (profiles of over 10 m to be tempered, galvanized sheets with specific aspects, etc.);
process developments to improve reliability and productivity (continuous lines for sheet metal, etc.);
the variety of possible products, in terms of appearance (flowered, shiny, chromated...), coating composition (Zn, Zn-Al, Zn-Fe...) and thickness range, with improved corrosion resistance.

Long an art, galvanizing has become a science where sophisticated technology and indispensable know-how go hand in hand with success.

Conclusion

Economic data

Annual world zinc production is 9 Mt, of which more than 50% is devoted to steel production (growth of around 3% per year).

There are 550 continuous galvanizing lines worldwide, producing 70 Mt of coated steel.

In Europe, automotive consumption will reach 8 Mt in 2005.

In Europe, 1.7 Mt/year...
