It features high forming accuracy, good straightness, and an integrated waterproof structure designed to address water penetration, water accumulation, rust, and corrosion inside traditional trailer side beams.
The profile has a smooth surface without burrs and combines strength with toughness. It is resistant to deformation and cracking and is suitable for the complex operating conditions of trailers, providing a high-strength and lightweight profile option for trailer manufacturing and modification.
Applications
The Waterproof G Shape Side Beam is suitable for trailer body manufacturing, repair, and refurbishment.
Trailer Manufacturing
Suitable for the side frames, guardrail bases, and main load-bearing side structures of:
- 13m curtain-side semi-trailers
- Box semi-trailers
- Warehouse-type trailers
- Light-duty freight trailers
Trailer Repair & Refurbishment
Used to replace old side 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 vehicle weight and is suitable for general cargo, fresh produce transportation, building materials, and other road transportation applications.
Special Light-Duty Trailers
Suitable for side protection and load-bearing structures of engineering machinery trailers and material transportation trailers, including applications exposed to long-distance travel, rain, snow, and humid conditions.
Key Advantages
High Load-Bearing Capacity with Grade 700 Steel
Made from high-strength steel specifically for trailer applications, the Grade 700 material provides high yield strength and strong resistance to impact and compression. Compared with ordinary profiles, it provides stronger overall load-bearing performance and is less prone to deformation or cracking under road vibration and compression.
G Shape Waterproof Structure
The integrated water-guiding channel structure can quickly drain rainwater and muddy water, helping prevent water accumulation and corrosion inside the profile and extending the service life of the trailer body.
Lightweight Design
The thin-wall specification provides high load-bearing performance while helping reduce overall vehicle weight. This can increase effective cargo capacity and reduce vehicle fuel consumption, supporting lightweight trailer manufacturing requirements.
One-Piece Forming for Easy Assembly
The full 13m profile is formed without splicing. Stable dimensions and high 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 G-shaped cold-bent structure with a built-in water-guiding and waterproof channel.
- Wall Thickness: 2.5mm
- Cross-Section Width: 14mm
- Standard Length: 13m
- Material: Grade 700 high-strength steel for trailer applications
- Section: Uniform and regular cross-section with dimensional tolerances meeting industry standards
- Structure: One-piece G-shaped cold bending
- Waterproof Design: Built-in water-guiding channel inside the profile
- Reinforcement: Side bending structure improves bending and torsional resistance
- Edges: Smooth profile edges without burrs or concentrated stress points
- Sealing Structure: The G-shaped slot can closely fit wall panel sealing strips to form an enclosed waterproof structure
- Surface: Flat base surface suitable for further processing
- Further Processing: Supports drilling, welding, painting, and galvanizing
Manufacturing Process
The side beam is manufactured through fully automatic one-piece cold bending forming.
The entire 13m profile has no break points or spliced sections. The base surface is flat and suitable for subsequent processing such as drilling, welding, painting, and galvanizing.
