What Is a Flat Top Trailer?

A flat top trailer, also known as a flatbed trailer, is an open-deck trailer with a flat loading surface and no fixed box sides. It is commonly used for transporting machinery, pallets, building materials, equipment, vehicles and oversized loads that require easy loading from multiple sides.

Flat top trailers are available in single axle, tandem axle and heavy-duty configurations depending on the load capacity, trailer size and towing requirements.

Why Choose a Flat Top Trailer

A flat top trailer is useful when you need open access from the sides, rear or top. Unlike enclosed or high-sided trailers, the flat deck layout makes it easier to load irregular items, machinery, pallets and bulky materials.

Flat top trailers are commonly used for:

• machinery and equipment transport
• construction materials
• agricultural loads
• trade and contractor work
• palletised goods
• oversized or irregular cargo
• commercial transport applications

Built for Heavy-Duty Transport

Flat top trailers are a strong choice for customers who need a durable trailer platform for regular loading and hauling. The open deck design gives operators more flexibility when carrying larger items, while the heavy-duty chassis and suspension options support practical work use.

Depending on the build, your trailer may include:

• reinforced steel construction
• checker plate or perforated flooring
• LED lighting
• rocker roller suspension
• heavy-duty draw bar
• brake options
• spare wheel bracket
• custom paint or finish options

All Roshar flat top trailers come with an 18-month structural warranty for your confidence in purchasing.

On-Road and Off-Road Options

Roshar Trailers builds flat top trailers for both on-road and off-road use.

On-road flat top trailers are suited to trade, construction and commercial transport on public roads, and are built to comply with Australian Design Regulations (ADR) and Australian Safety Standards.

Off-road flat top trailers are built for customers working in mining, agriculture or rural environments where terrain is uneven or access roads are unsealed. These trailers are designed with enhanced stability and durability for demanding conditions.

 

Flat Top vs Flat Bench Trailers

Flat top and flat bench trailers are similar, but they may suit different applications depending on deck layout, loading style and intended use.

A flat top trailer is generally suited to broad open-deck transport where side and top loading access are important.

A flat bench trailer may be better when you need a more specific bench-style layout or a different trailer platform. For that option, visit our Flat Bench Trailers page.

Single Axle vs Tandem Axle Flat Top Trailers

Feature	Single Axle Flat Top Trailer	Tandem Axle Flat Top Trailer

Flatbed Trailer Options

If you are searching for a flatbed trailer, a flat top trailer may be the right fit. These trailers are commonly used where open loading access, deck space and flexible cargo handling are more important than enclosed storage.

Flatbed-style trailers are useful for:

• pallets
• long materials
• machinery
• equipment
• construction supplies
• rural and commercial loads

Not every customer needs the same trailer setup. Roshar Trailers can assist with custom sizing and practical upgrades based on your work requirements.

Custom options may include:

• custom trailer size
• floor type selection
• brake options
• suspension upgrades
• ramps
• paint or finish options
• side or loading modifications
• load-specific build changes

Flat Top Trailer for Machinery and Worksite Transport

A Melbourne-based contractor may need to move compact machinery, palletised materials and tools between job sites. A standard box trailer may not offer enough open loading space, while an enclosed trailer may limit side access.

In this case, a tandem axle flat top trailer provides a practical solution. The open-deck layout allows easier forklift loading, better access from multiple sides and more flexibility when carrying irregular or heavy items. With the right size, axle setup and tie-down points, the trailer can support regular commercial transport more effectively.
