2. Continuous galvanizing of sheet metal
Continuous galvanizing (and aluminizing) of sheet metal is described in the article Continuous galvanizing and aluminizing. . This presentation will therefore focus on product rather than process aspects.
2.1 General presentation
A rather traditional continuous-coating technology with applications in the building market (e.g. cladding and roofing), its progress has enabled the development of galvanized sheet metal with a regularity and quality of appearance that makes it suitable for use in the automotive and household appliance sectors.
The technical features of this process are, firstly, that it is continuous and, secondly, that it can couple several operations in the same industrial line, in a highly automated way....

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...
