3-Bend W Type Trailer Cross Member

1. Product Overview

3-bend W beam, also known as three-bend W-type cross member or trailer floor cross bearer, is a special high-strength steel profile for semi-trailers. It is integrally bent from high-strength steel plate with a W wave structure. As the core load-bearing cross member under the trailer floor, it shares the floor load and improves the overall torsion resistance of the trailer. Bulk export is supported.

2. Application Scenarios

• Floor support for warehouse semi-trailers, flatbed semi-trailers, box trailers and dump trailers
• Chassis reinforcement for container skeleton trailers and heavy-duty freight trailers
• New trailer assembly, maintenance and renovation of old trailer compartments, and accessory matching for overseas trailer manufacturers
• Chassis load-bearing structure for trailers under mining areas and long-distance heavy haul conditions

3. Core Advantages

1. High-strength steel material: Made of high-strength base material, featuring high strength and light weight. It reduces dead weight while ensuring load capacity and increases the effective cargo capacity of trailers.
2. Integrated forming with three bends: The integral W wave bending delivers excellent torsion and deformation resistance. It is not easy to deform or break under heavy load and bumpy conditions.
3. Uniform load distribution: The W-shaped structure transfers floor load evenly to the trailer main beam, buffers impact and protects the trailer floor.
4. Easy assembly and welding: Standard profile with smooth cuts, convenient for welding and assembly with main beams and floor plates, saving processing time.
5. Fatigue resistance and durability: Stamped and bent without splicing welds. It resists cracking under long-term repeated heavy load and has a longer service life.

4. Structure and Configuration Description

• Main body: Integrally bent long W-type C-channel profile with 3 wave bends
• Material: High-strength steel (700 high-strength steel commonly used)
• Thickness: 2.5mm, 3.0mm as standard options, selectable as required
• Process: CNC bending forming with flat end faces; pre-punching and cutting available
• Installation: Horizontally runs between the two main beams of the trailer, acting as the load-bearing cross member for the trailer floor
