An Underbody Truck Box mounts beneath the frame to protect tools while preserving bed space. We design and manufacture aluminum diamond plate and powder-coated steel boxes for demanding fleets. Established in 1995 with in-house R&D and our own production lines, we deliver certified quality and OEM customization. Standard sizes are available, and we can build custom Underbody Truck Boxes for pickups, flatbeds, service bodies, and trailers.
Built for daily use, our enclosures feature reinforced shells, continuous rubber seals, and secure latching. Stainless steel hinges, T-handle or paddle latches, and optional gas struts ensure smooth, reliable operation. Durable finishes resist corrosion and abrasion in harsh environments.
Heavy-duty construction with precise welds for long service life
Water- and dust-resistant sealing with continuous gaskets
Lockable security with anti-pry designs
Aluminum for low weight; steel for higher impact resistance
Optional trays, dividers, mats, and lighting for organization
Choose material, door style, latch type, size, and mounting side to match your vehicle and tasks. Aluminum cuts weight and fights corrosion; steel maximizes impact protection. Low-profile designs help preserve ground clearance; paired driver/passenger installs balance storage.
| Material | Weight | Corrosion | Impact | Best For |
|---|---|---|---|---|
| Aluminum | Lighter | High | Moderate | Coastal/snow regions, weight-sensitive fleets |
| Powder-coated steel | Heavier | Good | High | Construction sites, impact-prone work |
Verify frame rail spacing, ground clearance at full compression, and proximity to exhaust, fuel lines, and steps. Mount on driver or passenger side with vibration-resistant hardware and correct torque. Ideal for construction, utilities, agriculture, landscaping, and municipal fleets using pickups, flatbeds, and utility or enclosed trailers.
Select low-profile boxes to protect ground clearance on rough sites.
Use paired boxes to distribute weight and organize tools.
Match latch style to glove use and security requirements.
Measure available length, height, and depth. Select material and finish for climate, corrosion, and weight goals. Pick door orientation and latch based on access and security. Plan accessories such as dividers, mats, gas struts, and lighting. Maintain seals and hinges to extend service life.
Our engineers tailor dimensions, door layouts, latch/lock systems, branding, and interior organization to your application. We support CAD review, prototyping, and sampling to meet OEM and fleet standards.
We operate a 30,000 m² factory with ISO9001 quality and ISO14001 environmental systems and hold a positive BSCI report. Selected products carry VPA certification. Testing covers weld integrity, sealing, and finish durability.
