Printed steel plate, also known as printed color steel plate, refers to a process where various patterns are printed onto steel plates using technical means on the basis of different base plates.

The substrate can be cold-rolled, electroplated zinc, hot-dipped zinc, or aluminum-zinc coated steel, with the appropriate material selected based on the specific application and its required mechanical properties.

Cold-rolled base plate produced colored coated steel sheets, with limited corrosion resistance, as any minor scratch on the surface coating will quickly develop red rust, affecting usability. The colored coating of this base plate is suitable for manufacturing internal parts of household appliances or for temporary, low-height partition barriers.

Electroplated zinc-coated steel sheets, with their zinc layer providing corrosion resistance superior to cold rolled coated sheets, offer better processing properties due to their thin zinc layer (typically containing 20g/m²). They are suitable for manufacturing products and components that require high corrosion resistance, such as the internal and external components of air conditioners, the casings of washing machines or refrigerators, decorative wall panels, furniture, lighting fixtures, signage, and more.

Galvanized aluminum steel sheets, since their introduction to the global market in the 1970s, have become popular for roofing and wall applications. The hot-dipped alloy coating of galvanized aluminum steel sheets contains 55% aluminum, 43.5% zinc, and 1.5% silicon, effectively combining the strength of steel, the corrosion resistance of aluminum, and the sacrificial protection of zinc against cuts and interruptions. In similar environments, the lifespan of steel sheets with the same coating thickness as galvanized steel 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 a stunning, light silver-gray lustrous appearance.
