Accuride's New ProShield XGT Coating Fights Corrosion, Cuts Maintenance

Key Details Accuride introduced ProShield XGT, a patent-pending aluminum wheel coating, at the Technology & Maintenance Council Annual Meeting. The new surface technology uses a metal conversion process that bonds directly to the wheel's aluminum microstructure, making the coating effectively part of the wheel itself. Why It Matters Filiform corrosion - threadlike corrosion that spreads beneath damaged coatings - costs fleets time and money. Modern deicing chemicals containing magnesium, calcium, sodium, and potassium chloride are more aggressive than ever, accelerating wheel deterioration in harsh winter conditions. Proven Performance Accuride subjected ProShield XGT to rigorous accelerated durability testing simulating eight years of real-world exposure. Engineers intentionally damaged wheels to bare metal, then exposed them to repeated temperature swings, humidity cycles, and chemical exposure. After 80 test cycles, wheels showed no significant filiform corrosion compared to traditional coatings. Fleet Benefits ProShield XGT maintains factory-gloss finish throughout wheel life and simplifies cleaning in harsh environments. The coating prevents corrosion from spreading even when surface damage occurs, extending overall wheel longevity and preserving appearance. For fleets managing maintenance budgets, this means reduced downtime and lower replacement costs.
