To withstand the high temperatures and strong UV rays of the Middle East, Hegang Steel's PVDF color-coated steel coils achieve a technological breakthrough with a four-layer protection system: epoxy primer (5μm) + fluorocarbon topcoat (20μm) + nano-titanium dioxide barrier layer, resulting in UV resistance of up to 3,000 hours (ΔE ≤ 2). Field testing in Dubai has shown that its 115° hydrophobic surface reduces building energy consumption by 30%, and its resistance to 10% hydrochloric acid exceeds industry standards. By 2025, 50,000 tons of custom color-coated steel coils had been delivered to the UAE, with a color difference control accuracy of ΔE ≤ 0.5.
