Applications
The 80×2.5×2540mm Open Straight Strut is suitable for various curtain-side semi-trailer manufacturing and assembly applications.
- Production and assembly of curtain-side semi-trailers
- Horizontal and vertical support structures for trailer frames
- Replacement and repair of deformed or rusted frames on older trailers
- Lightweight trailer projects for general cargo transportation
Key Advantages
High-Strength Load-Bearing Performance
Grade 700 high-strength steel provides strong load-bearing performance and resistance to compression and impact. The profile is less prone to deformation under cargo pressure.
Precise One-Piece Forming
The one-piece formed structure provides accurate dimensions, small assembly gaps, and good welding fit-up.
Good Weather Resistance
The profile is suitable for long-distance transportation and complex road conditions, with resistance to rust and cracking.
Easy Installation
The precise profile helps reduce on-site correction and grinding work, improving trailer assembly efficiency.
