Double Side Prepainted White Color Metal

White pre-painted metal sheets are widely used in four core applications: building envelopes (factories/airports/temporary housing), home appliance casings (refrigerators/washing machines), transportation (interiors/road signs), and interior decoration (wall panels/cladding). White pre-painted metal sheets are composite materials made from galvanized steel, aluminum-zinc coated steel, or cold-rolled steel sheets as the base material, coated with polyester (PE), silicon-modified polyester (SMP), high-durability polyester (HDP), or fluorocarbon (PVDF) coatings, and then cured by high-temperature baking. The white coating not only provides a uniform and aesthetically pleasing visual effect but also possesses practical properties such as rust resistance, weather resistance, and ease of cleaning. Typical thicknesses range from 0.2–1.2mm, and common colors include snow white, milky white, imperial white, and light gray. White pre-painted metal sheets have surpassed the traditional building material positioning, becoming a cross-industry standardized surface solution: supporting large-span metal roofing systems in the construction sector, driving appearance innovation in the home appliance sector, and meeting both fire resistance and cleanliness requirements in interior applications. When selecting, key considerations include the base material type (galvanized/aluminum-zinc coated), coating type (PE/SMP/HDP/PVDF), and fire rating (A/B1 class) to match the lifespan and safety stand.
