Century Trailers offers Flat Top Trailers with certified ATM ratings of 3,200 kg, 3,500 kg, and 4,500 kg. To calculate legal payload capacity, subtract the tare weight (unladen trailer weight, typically 900 kg to 1,500 kg depending on chassis size) from the ATM rating. For instance, our 3,500 kg ATM trailer with an 1,100 kg tare provides a massive legal payload of 2,400 kg.

Both series are hot-dip galvanised and ADR-compliant, but they cater to distinct commercial applications:

• Q-Series (Commercial Trade Workhorse): Engineered for general building contractors, landscapers, agricultural transport, and trade supplies. It features high-tensile RHS chassis construction optimized to deliver the highest possible legal payload with exceptional cost efficiency. Perfect for palletised freight, materials, and light equipment.
• X-Series (Heavy-Duty Extreme Spec): Built for civil earthmoving contractors, heavy plant machinery hauling, and harsh Australian industrial conditions. The X-Series boasts heavily reinforced main chassis runners, additional cross-member gussets, upgraded heavy-wall checker plates, and high-tensile perimeter tie-down systems designed to handle point-load stress from steel tracks, excavators, and bobcats.

Buyer Recommendation: Choose the Q-Series if your primary focus is versatile commercial hauling, pallet transport, and optimal return on investment. Choose the X-Series if you regularly haul heavy concentrated plant machinery or operate on rough regional and unsealed worksites.

Yes, heavy-duty structural aluminium or steel loading ramps are available. Century Trailers has completely re-engineered our ramp mounting system based on years of manufacturing, customer feedback, and real-world Australian trade experience.

Traditional underbody slide-away storage frequently suffers from road gravel impact, grit, and mud accumulation, causing under-chassis runners to jam, rattle, or suffer stone damage. To solve this, Century Trailers mounts ramps securely on the reinforced front panel (headboard).

This upright front-mount design delivers significant advantages:

• Zero Jamming: Free from road debris, dust, and gravel buildup.
• Greater Ground Clearance: Eliminates the risk of ramps bottoming out or dragging across gutters and rough site entries.
• Fast & Safe Deployment: Ergonomic quick-release locking pins allow single-operator setup in seconds without bending under the trailer.

With an unobstructed over-wheel deck and zero wheel-arch interference, our Flat Top models are custom-dimensioned for standard Australian pallets (1165×1165mm):

• 10×6 ft & 10×7 ft: Comfortably carries 2 standard pallets with generous tie-down clearance.
• 12×7 ft: Fits 4 standard Australian pallets loaded two-by-two side-by-side.
• 14×7 ft & 16×8 ft: Carries 4 to 6 pallets with dedicated space for tools and accessories.
• 6m (20×8 ft) Tri-Axle: Accommodates up to 8–10 pallets, structural long-length steel, or 20ft shipping containers.

Yes. All Century commercial Flat Top trailers come standard with heavy-duty drop-down and fully removable zinc-plated side gates and tailgates. The front headboard can also be detached or lowered when hauling extra-long timber, pipes, or machinery overhangs, enabling 360° unrestricted forklift loading.

Under Australian Design Rules (ADR):

• 3,500 kg ATM Models: Equipped with dual-axle 12" electric drum brakes, a 50mm quick-release ball coupling, and an ADR-approved electric breakaway battery safety system.
• 4,500 kg ATM Models: Fitted with heavy-duty 70mm ball or pintle hook couplings, 50mm heavy-duty solid axles, high-tensile safety chains, and upgraded 12" electric or hydraulic braking kits.

Yes. All Century branches provide fast on-site Queensland Registration services. You can drive away fully registered with official QLD plates on the same day. Collection is available at our 4 Queensland showroom yards: Brisbane (Rocklea), Gold Coast (Arundel), Toowoomba, and Caboolture.

Hot-dip galvanising submerges the entire welded chassis and deck into molten zinc at approximately 450°C. This bonds zinc to both internal hollow sections and exterior surfaces, delivering permanent rust and corrosion protection against coastal salt air, road grime, and harsh worksite chemicals—delivering decades of lifespan without peeling paint.
