Our Turkish-made commercial trailer steel wheels are forged from high-tensile, certified automotive-grade sheet steel. They undergo rigorous testing—including dynamic cornering fatigue tests and radial rolling fatigue analysis—to comply with strict European safety standards.
Advanced Flow-Forming Technology: Specialized cold-spinning processes refine the steel’s crystalline structure, allowing us to produce a weight-optimized wheel design that reduces fuel consumption without compromising maximum load capacity.
Precision E-Coat Anti-Corrosion Protection: Every wheel rim undergoes a multi-stage Cathodic Electrodeposition (CED) primer coating followed by a durable topcoat. This provides exceptional resistance against salt spray, chemical road de-icers, and harsh environmental weathering.
Flawless Zero-Defect Welding: Computer-controlled, high-precision automated submerged arc welding ensures an unyielding bond between the wheel disc and the rim, preventing micro-fractures and air pressure leakage.
Perfect Balance & Radial Runout Control: Engineered with strict tolerance thresholds (less than 1.0 mm) to minimize tire wear, eliminate highway steering vibrations, and lower total fleet maintenance costs.
