One Trailer. Infinite Cargo Possibilities.

What is a Flatbed Semi-Trailer?
A flatbed semi-trailer (also known as a platform trailer) is the ultimate multi-purpose vehicle for global logistics. Unlike skeletal trailers, it features a solid reinforced steel deck and 12 ISO twist locks, allowing it to transport 20ft/40ft containers as well as bulk un-containerized cargo such as construction materials, pipes, and heavy machinery.
1. Maximizing Utility: Flatbed vs Skeleton
While skeletal trailers are limited to port-to-port container work, the Kales Flatbed is designed to eliminate "empty return trips," significantly boosting fleet ROI:
- 📦 Dual-Purpose Deck: Equipped with 12 ISO Twist Locks for 1x40ft or 2x20ft containers, plus a full flat surface for return-trip bulk cargo.
- 🏗️ Concentrated Load Support: Unlike generic trailers, our cross-beams are spaced every 40-50cm to prevent "bowing" under concentrated point loads like steel coils.
- 🛡️ High-Friction Safety: The floor is made of 3mm / 4mm checkered plate, which increases grip by 35% compared to smooth steel plates.
- 🔗 Expandable Design: Built-in post sockets along the side beams allow you to add stakes or side walls in the future.
🌍 Field Case: Multi-Cargo Logistics in West Africa
"We delivery containers from the port to inland hubs. Previously, our skeleton trailers returned empty. By upgrading to Kales Flatbeds, our drivers now pick up lumber or bagged cement for the return journey. Despite the 50-ton heavy bagged cargo, the T700 reinforced cross-beams have kept the floor perfectly flat after 24 months of use."

2. Industrial Grade Manufacturing & Finish
Reliability is built into every weld and paint layer. We follow a strict industrial protocol to ensure 10+ years of service life:
High-Density Bracing
Dense diagonal supports under the floor eliminate "point load deformation," ensuring the 3mm/4mm plate stays level forever.
Reinforced Gooseneck
Double-layer T700 steel plates at the gooseneck handle the massive stress of sudden braking with a 60-ton load.
Polyurethane Paint
Following Shot Blasting to remove rust, we apply 2 primers and 2 top coats of polyurethane paint for 5+ years of anti-corrosion.
3. Premium Component Specification

6. Frequently Asked Questions (FAQ)
What is the main difference between a Flatbed and a Skeleton Chassis?
The primary difference is the loading platform. A flatbed trailer has a reinforced steel floor, allowing it to carry bulk cargo (cement, steel, wood) in addition to containers. A skeleton chassis only has a bare frame and can only carry ISO containers.
How do you pack these trailers to save on freight?
To minimize ocean freight, we utilize the Stacking Method. We stack 3 units together as one bundle for Bulk Cargo shipment. This reduces the total shipping volume and can save you up to 30% on transport costs.
Can I add side walls or stakes to this trailer?
Yes. We can design the side beams with integrated post sockets. This allows you to install removable stakes or side walls later if your cargo requirements change from containers to loose agricultural or construction goods.
