Carrier has gone from solvent based paint to precoated steel in order to reduce wastes associated with painting. The Tyler facility has completely gotten away from any coating operations on it's metal fabrication operations.
The precoated steel required Carrier to redesign shearing and stamping to more rounded bends instead of sharp folds so as not to separate the coating from the sheet metal. Special carts to move formed sheets were made with spacers to prevent damage to the coated surfaces. The net result is that all sub assemblies were treated with more care significantly reducing damage and the generation of metal scrap.
Going from a solvent based system to precoated steel eliminated paint waste, paint sludge, air emissions and wastewater. Precoated steel eliminate over 80 tons of soild hazardous waste that Carrier generated as well as 12,000 pounds of VOC emissions, an important factor since the Tyler area is a near non-attainment area for ozone.

Additional Information :
Carrier has calculated that going to precoated steel cost $35,000 for new shearing and stamping equipment while saving over $500,000 a year in labor and waste disposal costs.
