Key Features
Strong chassis discipline, repeatable load securing, and stable road performance — with configurable axles, brakes, and suspension options.
Chassis & Structure
The Backbone. Engineered to Last.
Welded I-beam mainframe fabricated from ST52 / S355J2+N high-strength structural steel — engineered to absorb the cyclic fatigue loads of heavy daily haulage without deformation.
High-Strength Steel Grade
ST52 / S355J2+N provides 355 MPa minimum yield strength — a robust yet weight-efficient chassis that keeps tare weight low and maximises payload within legal gross vehicle weight limits.
I-Beam Mainframe Construction
Continuous I-beam longitudinal members precision-welded to tight fabrication tolerances — delivering a flat, true deck surface across the full platform length.
Axles & Suspension
Suspension Options to Match Your Market.
Air suspension for comfort, stability, and cargo protection on long-distance operations. Leaf spring / mechanical suspension for simplicity and service familiarity in markets that prioritise straightforward maintenance.
Air Suspension
Chosen for comfort, stability, and cargo protection — especially for long-distance operations where dynamic load transfer and road surface compliance matter.
Leaf Spring / Mechanical Suspension
Chosen for simplicity and service familiarity — especially in markets that prioritise straightforward maintenance and familiar running gear.
Axles, Brakes & Market Configuration
Configured for Your Service Network.
Axle brands configured to match your service network and spare-part availability — SAF, BPW, or TRAX by specification. Brake and suspension setups also configurable based on market requirements.
Axle Brand Selection
SAF, BPW, or TRAX axles by specification — matched to your service network and spare-part availability for lower downtime and easier maintenance across your fleet.
Brakes & EBS Options
Disc or drum brakes, EBS, and lifting axle options configurable based on market requirements. Deck and lashing equipment tailored to your cargo type and securing method.
Models in This Series
Standard Flatbed (2-Axle / 3-Axle)
The straightforward choice for general cargo and standard routes. Simple, robust, and efficient — fast loading, easy maintenance, and configurable for different markets.
Mechanical Steering Flatbed (2-Axle / 3-Axle)
A kingpin-driven mechanical linkage steers the last axle to reduce tire scrub and improve maneuverability — especially in roundabouts, yards, and tight delivery points.
Extendable Flatbed (3-Axle)
Extra deck length for long cargo — steel profiles, pipes, timber, precast elements. Available with self-steering last axle or full hydraulic steering on all three axles for maximum turning control.

Flatbed Trailer FAQs
What is a flatbed trailer used for?
Transporting cargo that is best loaded from the top or sides — steel, machinery, pallets, timber, construction materials, and containers (by configuration).
How do I choose between a standard flatbed and a steering flatbed?
Choose standard for simplicity and straight routes. Choose mechanical steering if tight turns, roundabouts, and yard maneuvering are common.
What is a mechanical steering axle on a flatbed trailer?
A system where a mechanical linkage steers the axle (typically the last axle) to reduce tire scrub and improve turning behavior.
What is the difference between mechanical steering and self-steering?
Mechanical steering is linkage-driven; self-steering is passive and follows cornering forces. Both improve maneuverability and reduce tire wear.
When should I choose an extendable flatbed trailer?
When you regularly carry long cargo — steel profiles, pipes, timber, precast elements — but don't need maximum deck length all the time.
Air suspension or leaf spring — what should I choose?
Air suspension for comfort and cargo protection on long-distance operations; leaf spring for simplicity and service familiarity in markets that prioritise straightforward maintenance.
Can I choose axle brands like SAF / BPW / TRAX?
Yes — configurable by specification to match your market and parts availability.
Can you configure the trailer for ISO container transport?
Yes — twist locks and container-related equipment can be configured by specification.
