Coatings applied to prepainted metal
Prepainted metal is a high quality product manufactured under strict quality control in the coil coating process. The main substrates for prepainted metal are steel and aluminium strip and these are usually coated with a liquid paint by roller-coating, although sometimes a pre-formed film is laminated to the surface and occasionally a powder-paint is applied in coil coating.
A prepainted metal product is a synergistic combination of the metal substrate, any metallic coating which may be used, an efficient cleaning and chemical conversion process and usually 2, but up to 4 different paint coatings. The coil coating process allows different coatings to be used on the two sides of the metal strip, so the possibilities are endless.
Each producer of prepainted metal offers their own, sometimes branded, selection of prepainted metal products. It is beyond the scope of ecca to compare all of these products, but we have produced a Technical Paper which provides a guide to the main product types, together with their main uses, advantages and disadvantages.
