Robotic Welding Cells
We deploy advanced robotic welding arms for long, continuous seams on trailer chassis, ensuring perfect penetration and rapid production times without operator fatigue.
📏
Long-Bed Press Braking
Forming heavy truck frame rails requires massive machinery. Our facility features press brakes capable of bending high-strength steel plates up to 15 meters in length.
🎨
Industrial Coating Lines
Transportation parts fight road salt and weather daily. Our massive steel grit blasting and painting booths apply heavy-duty epoxies and polyurethanes for maximum corrosion resistance.
🔍
Strict OEM Metrology
Utilizing large-scale laser trackers and CMMs, we verify that every suspension mounting point and axle bore is machined to the exact OEM tolerance.
