Prepainted coil is leveled and cut to length or roll formed to the ordered profile.
Shearing, profiling, film application, inspection and protected stacking must avoid coating damage.

Typical applications

Roof and wall panels
Doors, ceilings and interior partitions
Equipment housings and decorative fabrication

Quality and acceptance controls

Verify substrate grade, metallic coating and organic coating system as three separate order requirements.
Check dry-film thickness, adhesion, color, gloss, surface appearance, forming performance and back coat.
Agree color tolerance, protective film, cut-edge treatment, coil or bundle packing and dry storage before shipment.

Include in your RFQ

Substrate grade and metallic-coating specification
Paint chemistry, primer, top/back coat and dry-film thickness
Color standard, gloss and permitted color tolerance
Thickness, width or profile geometry, tolerances and quantity
