One common issue with outdoor PPGI material is surface rusting. Some coatings labeled as rust-resistant for 10-25 years develop rust spots within less than a year. What causes this phenomenon? And how can we resolve or prevent it? Causes of Rust Formation on PPGI Steel Coatings Production-Related Factors Uneven or insufficient zinc coating thickness: The […]

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

Cold-rolled stainless steel and hot-rolled stainless steel are the two primary processing methods for stainless steel sheets. The versatility of cold-rolled stainless steel is evident in various aspects, including surface types (2B/2D/BA/NO.4/Hairline, etc.). The surface type of stainless steel determines its “appearance, roughness, and subsequent processability,” making it suitable for applications such as decoration, anti-slip,

When manufacturing galvanized steel, galvanized aluminum-zinc steel, galvanized aluminum-magnesium-zinc steel, and color-coated steel sheets, the term “cold-rolled steel plate” is frequently mentioned. It refers to steel plates or steel strips produced through the cold-rolling process. Cold-rolled steel plates are produced by rolling hot-rolled steel plates, but they have superior surface quality, dimensional accuracy, and mechanical
