Custom Trailer Chassis Fabrication for Heavy Transport
Trailer chassis serve as the primary load-bearing structure for a wide range of transportation equipment, including flatbed trailers, tankers, lowboys, and modular transport systems. These structures must withstand continuous dynamic loads, torsional stress, and harsh road conditions over long service lifecycles.
Openex manufactures heavy-duty trailer chassis using high-strength structural steel and advanced fabrication processes. From prototype development to high-volume production, we support OEM trailer manufacturers with consistent quality and scalable capacity.

Trailer Chassis Manufacturing Process
High-precision CNC cutting ensures accurate structural profiles and connection interfaces for cross members and suspension mounting points.
Long-bed press brakes form main beams and structural sections with high consistency across large production runs.
Automated welding ensures strong, uniform weld seams across long chassis structures, improving durability and reducing human variability.
Steel grit blasting and industrial coatings protect against corrosion, road salt, and environmental exposure.
