Modern Matt Prepainted Galvanized Steel Solutions

Modern Matt Prepainted Galvanized Steel Solutions Matte finish galvanized steel products are produced by applying low-gloss organic coatings to hot-dip galvanized steel substrates. The coating system typically consists of a chromate-free conversion coating, an epoxy primer (5–15 μm dry film thickness), and a topcoat formulated with polyester (PE), siliconized polyester (SMP), or polyvinylidene fluoride (PVDF) resins incorporating matting agents such as silica or wax. The resulting surface exhibits a gloss level of ≤30 GU measured at 60°, which reduces glare and minimizes light reflection. Substrate specifications include minimum zinc coating weights of Z100 (single side) per EN 10346, with steel grades ranging from DX51D to S350GD depending on mechanical requirements. Performance characteristics include adhesion (cross-cut ≥Gt1 per ISO 2409), impact resistance (≥9 J), and flexibility (T-bend ≤2T for DX51D, ≤3T for higher strength grades). For exterior applications, accelerated weatheri…
