Truck Frames

Heavy-Duty Truck Frame Fabrication for OEMs

Truck frames form the structural backbone of commercial vehicles, supporting dynamic loads, torsional stress, and long-term fatigue. Openex manufactures high-strength truck frames for heavy-duty trucks, mining vehicles, and off-road equipment using advanced fabrication technologies and strict OEM tolerances.

With large-scale production capabilities and robotic welding systems, we deliver both prototype and high-volume truck chassis fabrication for global transportation manufacturers.

Truck Frame Manufacturing Process

1
Precision Cutting & Hole Processing

CNC laser and plasma cutting ensures accurate profiles and pre-engineered mounting holes for rapid assembly.

2
Heavy Bending & Forming

Long-bed press brakes form frame rails with high consistency and minimal distortion.

3
Robotic Welding

Automated welding guarantees uniform weld penetration, structural strength, and repeatability.

4
Inspection & Finishing

Each frame undergoes dimensional inspection and protective coating for corrosion resistance.

Applications

  • Heavy-duty commercial trucks
  • Mining and off-road vehicles
  • Construction equipment transporters
  • Specialized logistics vehicles
