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

The flexibility of pre-painted metal (PPGI, PPGL, and PPAL) impacts product performance, lifespan, and end-use applications. The flexibility of color-coated aluminum alloys and color-coated steel is influenced by multiple factors, including the substrate and the surface coating system. Today, we will compare four mainstream coatings: PE (polyester), PVDF (polyvinylidene fluoride), HDP (high-weather-resistant polyester), and SMP
