Flat Deck Trailers in Adelaide

A flat deck trailer (also called a flatbed or flat top trailer) is an open-platform semi-trailer with a completely flat loading surface and no sides or roof. This design provides maximum versatility for loading and unloading from any direction (top, sides, or rear) using forklifts, cranes, or side loaders. Flat decks are among the most common trailer types in Australian freight operations, used for transporting palletised goods, building materials, machinery, containers, steel, timber, and general freight. Their open design makes them ideal for loads of varying shapes and sizes, while container twist locks allow secure transport of shipping containers.

AAA Trailers offers a complete range of flat deck trailers for sale in Adelaide suitable for metro, regional, and interstate haulage work.

AAA Trailers offers a complete range of flat deck trailers for sale in Adelaide, including:

• Flat Top Lead (A) Trailer - 12 Pallet (11.4m) - ideal for lead trailer applications with 20ft container pin compatibility
• Flat Top B Trailer - 22 Pallet (13.72m) - our most popular configuration for general freight and container work
• 45' Flat Top Extendable - extends from 13.72m (closed) to 21.4m (extended) for over-length loads like machinery, steel beams, and extreme freight
• Flat Top Refrigerated Trailer - 22 Pallet (13.72m) - equipped with Thermo King refrigeration for temperature-controlled freight

All models are built on high-tensile steel mainframes with forklift-rated chequer plate floors and can be customised to match your specific freight profile.

Flat deck trailers are versatile workhorses suitable for transporting:

• Palletised freight and general cargo
• Building materials and construction equipment
• Containers (20ft and 40ft with appropriate models)
• Heavy machinery and plant equipment
• Agricultural products and rural freight
• Steel, timber, and other long materials (especially with extendable models)
• Temperature-sensitive goods (with refrigerated models)

The open platform design and container pin systems make them adaptable for Adelaide metro runs, regional South Australian hauls, and interstate work.

The main differences are:

12-Pallet Lead (A) Trailer:

• Length: 11.4m (deck: 7.4m)
• Tare weight: Approx. 7.9T
• Designed as a lead trailer for A-double and B-double combinations
• 20ft container pins standard

22-Pallet B Trailer:

• Length: 13.72m
• Tare weight: Approx. 9T
• Full-size workhorse for standard linehaul work
• 3-way container pins for greater versatility
• Suitable for both lead and rear positions

Both have the same 47T ATM and 23.5T GTM, with the choice depending on your configuration needs and freight type.

The AAA 45' Flat Top Extendable extends from 13.72m (closed) to 21.4m (extended), giving you nearly 8 metres of additional deck length. This makes it perfect for over-length loads such as excavators, steel beams, long pipes, or other machinery that exceeds standard trailer dimensions. Despite the extension capability, it maintains a 47T ATM and approximately 11T tare weight.

The Flat Top Refrigerated Trailer comes equipped with a Thermo King refrigeration unit of your choice and can operate in:

• Single Zone - maintain one consistent temperature throughout
• Dual Zone - run two different temperature zones simultaneously, ideal for mixed loads

The trailer features comprehensive insulation: 100mm on the roof, floor, and front wall; 76mm on rear doors; and 45mm on side walls. It includes pallet loading bars for double-stacking and a heavy-duty extruded aluminium duct floor for optimal airflow.
