Printed steel sheet, also known as printed color steel sheet, is a process where various patterns are printed onto steel plates using technical means, based on different substrates.
The substrate can be cold-rolled, electro-galvanized, hot-dip galvanized, or aluminum-zinc coated steel sheets. The appropriate material with suitable mechanical properties should be chosen based on the specific application.
Cold-rolled base plates, produced from cold-rolled base plates, have limited corrosion resistance. Any minor scratch on the surface coating will quickly develop red rust, affecting usage. The colored coating of this base plate is suitable for making internal parts of household appliances or for low-height temporary barriers.
Electroplated zinc-coated steel sheets offer superior corrosion resistance compared to cold-rolled coated sheets due to the protective zinc layer. With a thin zinc layer (typically 20g/m2), they have better processing properties than hot-dipped zinc. When manufacturing products and components that require high corrosion resistance, consider using electroplated zinc steel sheets as the base for coated plates. This includes internal and external components of air conditioners, washing machine or refrigerator casings; interior decorative walls, furniture, lighting equipment, signs, and more.
Galvanized aluminum steel sheets, since their introduction to the global market in the 1970s, have become a popular choice for roofing and wall steel. The hot-dip alloy coating of galvanized aluminum steel sheets contains 55% aluminum, 43.5% zinc, and 1.5% silicon, effectively combining the strengths of steel, the corrosion resistance of aluminum, and zinc's sacrificial protection of cuts and gaps. In similar environments, the lifespan of steel sheets with the same coating thickness as galvanized steel sheets is about four times longer. Galvanized aluminum steel sheets offer an excellent price-performance ratio, with costs significantly lower than stainless steel or aluminum sheets, and they boast a pleasing, light silver-gray luster.
