Note: The 53ft flatbed has the highest payload and floor load of the NA trailer trio because there is no box structure — just the steel deck. Freight is exposed to weather and must be secured with chains or straps. State permits are required for loads exceeding legal height, width, or weight limits.

Loading Specifications

Deck capacity, floor load, and FMCSA 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

Highest of the NA trailer trio — open steel deck accepts concentrated loads that enclosed trailers cannot. *Subject to legal height and permit requirements.

Weight limits (FMCSA)

Federal bridge law limits for 5-axle combinations

Max GVW (federal) 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 flatbed's lighter tare (~5,900 kg vs ~6,350 kg for a dry van) gives it roughly 400–500 kg more net payload at the same 80,000 lb GVW limit.

Common freight types

Structural steel, lumber, coiled steel, heavy machinery, construction equipment, large industrial components, and oversized cargo requiring side or crane loading. Freight must be secured with chains or straps and tarped if required.
