What prep work are you doing to the sheet prior to powdercoating? Our facility uses a 3-stage wash to remove any contaminants from the surface before painting. If the finish is peeling off it would be an indication that the surface of the sheet is not clean.

Also, if any welding has been done to the material, the scale around the weld must be removed or proper adhesion of the powdercoat will not occur.
