Note: The 53ft flatbed has the highest payload and floor load of the North American trailer trio because there is no box structure — just the steel deck. It is open to the elements, so freight must be secured with chains or straps and tarped if needed. Special permits are required for loads exceeding legal height, width, or weight limits.

Loading Specifications

Deck capacity, floor load, and DVSA weight limits

Deck capacity

Open steel deck — 16,154 × 2,591 mm with full side and rear access

GMA pallet positions (48 × 40 in) 30 deck positions
Deck positions — turned 90° up to 34 positions
Typical freight: steel, lumber, machinery no height limit*
Floor load limit 7,000 kg/m²

Among the highest of any standard semi-trailer — open deck steel construction supports concentrated loads that enclosed trailers cannot accept. *Subject to legal height and permit requirements.

Weight limits (DVSA)

UK bridge law limits for 5-axle combinations

Max GVW (UK) 36,287 kg
Steer axle limit 5,443 kg
Tandem drive axle limit 15,422 kg
Tandem rear axle limit 15,422 kg
Typical net payload ~22,000 kg

Bridge formula: The UK bridge formula limits axle group loads based on axle spacing. For a standard 5-axle flatbed, the practical payload ceiling is roughly 29,000–30,000 kg. The flatbed's lighter tare (~5,900 kg vs ~6,350 kg for a dry van) gives it roughly 450 kg more net payload.

Common freight types

The 53ft flatbed is commonly used for open-deck freight in the UK: structural steel, lumber, coiled steel, heavy machinery, construction equipment, large industrial components, and oversized cargo requiring side-loading. Not weatherproof — freight must be secured and sheeted.

Deck length 16.15m
