Paint or powder coating will not adhere properly to a metal surface that isn't perfectly clean. A pickling and phosphating line is the cornerstone of high-quality finishing. The pickling stage uses acid to remove scale, rust, and other surface impurities. Following this, the phosphating stage applies a crystalline conversion coating. This phosphate layer provides two key benefits: it creates a micro-roughened surface that dramatically improves paint adhesion, and it adds a secondary layer of corrosion resistance. An automated line from Raymond ensures precise timing and chemical control throughout this critical pre-treatment process, guaranteeing a superior and durable final finish for your products.
