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

PPGI stands for Pre-painted Galvanized Iron, also known as Color-coated Galvanized Steel. PPGI coil is one of the most common forms of PPGI steel. Coils are widely favored across various processing sectors due to their ease of transportation and storage, as well as their flexible workability. PPGI Coil Specification Specification Details Thickness 0.12-1.5mm (Common: 0.12/0.14/0.16/0.18) Width

The core objective of surface treatment for galvanized steel is to “play to its strengths while mitigating its weaknesses”—preserving its excellent rust prevention (red rust resistance) capabilities while overcoming drawbacks such as susceptibility to white rust and poor coating adhesion. Currently, Wanzhi Group’s primary surface treatments for galvanized steel include passivation, phosphating, coating, sealing, and

Steel is a metallic material primarily composed of iron (Fe) with a carbon content below 2.11% (C<2.11%). Its carbon content typically ranges from 0.02% to 2.11%. Mechanical properties, machinability, and corrosion resistance can be enhanced by adding alloying elements such as manganese, silicon, chromium, and nickel. Steel can be classified based on chemical composition, smelting
