Continuous coil paint line within galvanizing line, Mexico

Problem

A large, high profile steel processing plant in Mexico had two large galvanizing lines and two continuous coil paint lines. The demand for painted product was rising and they wanted to produce more prepainted steel as economically as possible.

Solution

Bronx installed a complete, 3 coat paint line system into one of their large, high speed galvanizing lines. Uncoated, cold rolled steel coils are now fed into the entry end of the line and galvanized, fully pretreated, primed and finish coat painted product is produced off the line.

The added painting section can be run in series with the galvanizing section to produce a very high quality painted product, or the painting section can be by-passed to produce just a galvanized product. The painting section has quick change coater capability for both the primer paint and the top coat paint.

Result

The increased output of value added painted products from the galvanizing line has given the company a significant economic benefit, as the cost structure of producing painted product on the galvanizing line is extremely attractive. This strategy will become more and more popular around the world in the coming years.
