What is pre-painted steel?

Pre-painted steel is manufactured through a continuous coating process that utilizes cleaning, pretreating, painting, and curing in coil form. Typically painted with two-coat paint systems, the coils receive a primer and a finish color coating on the side meant for exterior exposure and the reverse side receives a primer and topcoat. This system creates very uniform, aesthetically pleasing steel.

There are many options when it comes to pre-painted steel and they can vary in:

  • Metallic coating thickness
  • Types of top-coatings (polyesters, acrylics, silicone-polyesters, etc.)
  • Color
  • Treatments and primers

Pre-painted steel is typically used when the appearance of the steel matters and the steel is meant for long lasting durability. For example, primer coats can help prevent undercutting of paint and make the steel corrosion resistant.
