Spray coating (powder coating) and roll coating are two common processes used for surface decoration and protection of color-coated sheets. While they may look similar, they differ significantly in mass production capability, durability, cost, and suitable applications. Today, join us in exploring a comprehensive comparison and understanding of these two coated materials, from their principles

When selecting pre-painted steel sheets (PPGI, PPGL), the substrate material is always mentioned. The substrate is one of the core factors determining the product’s anti-corrosion lifespan, application scenarios, and cost-effectiveness. Currently, the popular coated steel sheets on the market include Galvanized (GI), Galvalume (GL), and Zinc-aluminum-magnesium (ZAM). Today, let’s understand these three mainstream coatings from

The thickness of galvanized steel sheet refers to the thickness of the base metal (substrate), excluding the thickness of the surface zinc layer. There are several ways to express this thickness; some regions commonly use “gauge” (abbreviated as GA), while others use metric units (mm). Both methods are widely used in the field of metal

Color-coated steel has a service life of 8 to 30 years. Not only does the coating material play a crucial role, but its precise multi-layer coating structure is also the secret to the sheet’s longevity. The typical coating structure of color-coated steel consists of a pretreatment layer (passivation layer), primer, and topcoat. Together, they form

VCM stands for Vinyl Clad Metal or Vinyl Laminated Metal, referring to vinyl-coated metal panels. PCM stands for Pre-Coated Metal, referring to pre-coated steel sheets. VCM and PCM are two common metal surface treatment methods. PCM has lower processing costs and is widely applied. VCM is a more advanced surface treatment technology developed from PCM,
Wanzhi Group offers color-coated steel produced through three processing techniques: roll-coated color-coated steel, spray-coated color-coated steel, and VCM laminated steel. These products serve diverse applications spanning construction, interior decoration, industrial manufacturing, and high-end home appliances, balancing durability, aesthetics, and cost-effectiveness. Roll Coating Process Pre-coated metal materials produced via roll coating, also known as PCM (Pre-Coated
