It is suitable for complex trailer operating conditions and provides a high-strength load-bearing profile for trailer manufacturing and modification.
Applications
The Grade 700 Auxiliary Sub Beam is suitable for trailer body manufacturing, repair, and refurbishment.
Trailer Manufacturing
Suitable for the bottom load-bearing support structures of:
- Curtain-side semi-trailers
- Box semi-trailers
- Warehouse-type trailers
- Light-duty freight trailers
Trailer Repair & Refurbishment
Used to replace old sub beams that have become rusted, deformed, or damaged, helping restore the structural strength and operating performance of the trailer body.
Lightweight Trailer Projects
Can replace ordinary carbon steel profiles to reduce overall vehicle weight and is suitable for general cargo, fresh produce transportation, building materials, and other road transportation applications.
Special Light-Duty Trailers
Suitable for bottom load-bearing support structures of engineering machinery trailers and material transportation trailers, including long-distance applications involving rain, snow, and humid conditions.
Key Advantages
High Load-Bearing Capacity with Grade 700 Steel
Made from high-strength steel specifically for trailer applications, Grade 700 steel provides high yield strength and strong impact and compression resistance. Compared with ordinary profiles, it provides stronger overall load-bearing performance and is less prone to deformation or cracking under vibration and compression during driving.
Stable Structure and Bending Resistance
The one-piece formed structure provides strong bending and torsional resistance. It can stably distribute trailer chassis loads and help protect the main beam from damage caused by overloading.
Lightweight and Cost Reduction
The thin-wall specification provides high load-bearing performance while helping reduce overall vehicle weight, increase effective cargo capacity, and reduce vehicle fuel consumption.
One-Piece Forming for Easy Assembly
The full 9.6m profile is formed without splicing. Stable dimensions and forming accuracy make it suitable for mainstream trailer installation structures, reducing on-site correction, grinding, and welding work while improving assembly efficiency.
Stable Weather Resistance
The material provides a balanced combination of strength and toughness and is less prone to brittle cracking at low temperatures. It can adapt to complex road conditions and outdoor environments involving moisture, dust, rain, and snow.
Structure & Configuration
The product features an integrated cold-bent structure with uniform load distribution and stable structural performance.
- Cross-Section: 220mm
- Wall Thickness: 4.0mm
- Standard Length: 9.6m
- Material: Grade 700 high-strength steel for trailer applications
- Dimensional Tolerance: In accordance with industry standards
