Whether it’s lumber, piping, hay, palletized goods, or construction supplies, flatbed trailers, also known as open-deck trailers, can handle it all. Flatbed trailers are extremely versatile in their use, but that’s because, unlike enclosed trailers, there are many variations of flatbeds to choose from. If you’re considering a flatbed or open-deck trailer for your shipment, how do you know which one is best for your freight? This article will help you answer just that. Read on to better understand the different kinds of flatbed trailers that are available so you can make an informed decision on which one your freight needs.

Types of Flatbed Trailers

Flatbed trailers come in all shapes, sizes, and load capacities; each designed to carry different types of cargo. The one tricky part of flatbed shipping is choosing and finding the flatbed trailer that is capable of hauling your freight’s weight and size. It’s also important to note that anything exceeding legal dimensions and weight can be considered oversized and may require more to ship, such as state permits, police, escorts, or more.

*Important Note – Trailer capacity, weight, and dimensions mentioned in this article are general specifications and should be used as an estimated guideline. These can vary based on the trailer type, brand, or semi-tractor being used with it.  

• Standard flatbed
• Extendable flatbed
• Step deck / drop deck
• Stretch single step deck / drop deck
• Double drop
• Stretch / extendable double drop
• Removable gooseneck (RGN)
• Stretch RGN
• Conestoga
• Side kit

Standard Flatbed Trailers

Maximum Legal Weight: 48,000 lbs.

Maximum Legal Cargo Length: 48 to 53 ft.

Maximum Legal Width: 8 ft. 6 in.

Maximum Legal Height: 8 ft. 6 in.

Standard flatbed trailers are widely used and versatile, often the most popular of all flatbed trailers. They most commonly haul steel, lumber, and other kinds of building or construction materials.

Extendable Flatbed Trailers

Maximum Legal Weight: 43,000 lbs.

Maximum Legal Cargo Length: 48 to 80 ft.

Maximum Legal Width: 8 ft. 6 in.

Maximum Legal Height: 8 ft. 6 in.

Extendable flatbed trailers can also be known as flatbed stretch trailers. These trailers have an extendable deck to transport cargo that is too long for a standard flatbed, like a piece of large or heavy machinery. 

Step Deck/ Drop Deck Flatbed Trailers

Maximum Legal Weight: 48,000 lbs.

Top Deck: Maximum Legal Cargo Length: 11 ft.

Bottom Deck: Maximum Legal Cargo Length: 37 ft.

Maximum Legal Width: 8 ft. 6 in.

Maximum Legal Height: 10 ft. on the bottom deck, 8 ft 6 in. on the top deck

These trailers are referred to as either a step deck or a drop deck. They consist of a bottom deck and a top deck. These flatbed trailers are great for transporting freight that would exceed the height restriction on a standard flatbed; they are ideal for any tall loads that need to go under low bridges. They also make it easy to use ramps to load and unload freight. A common piece of freight they haul is tractors. 

Stretch Single Step Deck/Drop Deck Flatbed Trailers

Maximum Legal Weight: 45,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck: Maximum Legal Cargo Length: 35 to 63 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck: Maximum Legal Height: 10 ft.

These flatbed trailers are like step decks, except they can be extended to transport cargo that can be too long for a standard step deck. This can include goods like scaffolding or drilling and mining equipment. 

Double Drop Flatbed Trailers

Maximum Legal Weight: 36,000 to 40,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck (well): Maximum Legal Cargo Length: 25 to 29 ft.

Rear Deck: Maximum Legal Cargo Length: 9 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck (well): Maximum Legal Height: 11 ft. 6 in.

Rear Deck: Maximum Legal Height: 10 ft.

Double drop trailers are also good for cargo that is too tall and generally used to haul oversized freight. Double drop trailers are unique in that they have a longer piece of the trailer called the “well”.

Stretch/Extendable Double Drop Flatbed Trailers

Maximum Legal Weight: 40,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck (well): Maximum Legal Cargo Length: 29 to 50 ft.

Rear Deck: Maximum Legal Cargo Length: 9 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck (well): Maximum Legal Height: 11 ft. 6 in.

Rear Deck: Maximum Legal Height: 10 ft.

Like the standard double drop trailer, this one is also great for oversized freight. Since this trailer can be lengthened for longer loads, it’s ideal to carrier longer freight since it provides more support and prevents any overhang. It’s also common for this trailer to have two to three axles so it can support more weight. Common freight hauled by stretch double drops are pipes and steel beams.

Removable Gooseneck (RGN) Flatbed Trailers

Maximum Legal Weight: 42,000 to 150,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck: Maximum Legal Cargo Length: 30 ft.

Rear Deck: Maximum Legal Cargo Length: 9 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck (well): Maximum Legal Height: 11 ft. 6 in.

Rear Deck: Maximum Legal Height: 10 ft.

An RGN is one special flatbed trailer. They’re great for long, tall, and heavy freight! They have a detachable front that can be used to create a ramp for loading and unloading and can expand from three axles to over 20, to carry heavy items, like farming combines. However, it’s important to note that since these are more specialized, they can be tougher to find and more expensive to use for your flatbed shipping.

Stretch RGN Flatbed Trailers

Maximum Legal Weight: 42,000 to 150,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck: Maximum Legal Cargo Length: 29 to 65 ft.

Rear Deck: Maximum Legal Cargo Length: 9 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck (well): Maximum Legal Height: 11 ft. 6 in.

Rear Deck: Maximum Legal Height: 10 ft.

When you need an RGN that can haul longer freight, a stretch or extendable RGN can help. Just like the standard RGN, axles can vary, from three and up, depending on the freight weight. The only real difference with this RGN trailer is the main deck is extendable up to 65 feet long.

Conestoga Flatbed Trailers

 Maximum Legal Weight: 42,000 to 45,000 lbs.

Maximum Legal Cargo Length: 48 to 53 ft.

Maximum Legal Width: 8 ft. 6 in.

Maximum Legal Height: 8 ft.

One interesting fact about Conestoga trailers is that Conestoga is also a brand name for them. Conestogas are specialized, flatbed trailers that have a hard shell and rolling tarp system, which is great for freight that needs better protection from outside elements. These can be one of the most requested flatbed trailers due to their versatility. They can often be seen transporting freight like CNC machinery or helicopters.

Side Kit Flatbed Trailers

Maximum Legal Weight: 42,000 to 45,000 lbs.

Maximum Legal Cargo Length: 48 to 53 ft.

Maximum Legal Width: 8 ft. 4 in.

Maximum Legal Height: “technically” it’s 8 ft. 6 in. but because of sides, 6 ft. is more easily accomplished

Side kit trailers are like Conestogas in that they are flatbed trailers that offer more protection. These trailers have panels surrounding often made from plywood or fiberglass, allowing for tarping over the top. Side kits are great for freight that is not packaged or crated, like corn or watermelons.

Flatbed Trailer Tips

Match Your Cargo to the Correct Flatbed Trailer

It’s important to know your cargo and that you have the right flatbed trailer to transport it. If the wrong trailer pulls in and it can’t carry your freight, you’ve lost out on precious travel time. Additionally, having the correct trailer ensures safe transport.

Communicate the Details

Regardless of what kind of product you need to transport, a lack of detailed communication with your logistics provider is important to avoid confusion and setbacks. For a logistics provider to effectively support you with your flatbed shipping needs, you’ll need to share specific details such as:

• Dimensions of cargo (length, width, height)
• Cargo weight
• Type of commodity
• Does your freight have any sharp edges?
• Does it need tarped/element protection?
• Is your cargo multiple pieces or singular?
• Is your cargo loose or palletized?

Understanding Your Flatbed Trailer Needs

Understanding the different kinds of flatbed trailers there are helps you make more informed and cost-effective decisions. You’ll better know their limitations and whether they may be more costly and time-consuming to acquire. For example, by knowing that more specialized flatbed trailers like RGNs or Conestogas are tougher to obtain, you’ll know to give your logistics provider advanced notice for those shipments, giving you the benefit of a more successful relationship and potentially cheaper rates.

WHAT IS A FLATBED TRAILER? FLATBED SHIPPING?

Flatbed Shipping

Flatbed shipping is often the transportation choice for cargo that doesn’t need the enclosure of a dry van. It’s ideal for cargo that cannot be loaded or unloaded from a dock as the shipper or receiver can load or unload from a variety of ways. The design of a flatbed trailer allows for cranes and forklifts to unload and load goods from a loading dock, from the side with a forklift or crane, or from above with an overhead, gantry, or crawler crane. This makes a flatbed trailer versatile and critical for numerous loading and unloading scenarios including at job sites, warehouses, and distribution centers. 

Flatbed Trailer

A flatbed trailer is the most common type of open-deck trailer used in commercial, over-the-road, long-haul, and specialized trucking such as oversized or over-dimensional shipments. A flatbed trailer is a 48ft or 53ft trailer, that can accommodate loads up to 48,000lbs. They typically have two axles, air-ride suspension, and kingpin for a standard 5th wheel hook up. 

Flatbed Freight

Flatbed freight tends to be more industrial than truckload dry van freight. There is a wide variety of flatbed freight in the marketplace. Some higher volume products like lumber or building supplies will generally pay less than more industrial items that support our country’s energy and core infrastructure needs, like construction equipment, generators, fabricated steel, and other project or job site-related freight.

WHAT CAN BE HAULED ON A FLATBED TRAILER?

The most common freight shipping uses for flatbed trailers are:

o Formed concrete items

o Lumber

o Construction materials

o Steel beams

o Scaffolding

o Trusses

o Electrical transformers

o Oil, gas, and petrochemical equipment

o Solar panels or wind turbines

o Commercial heating and air conditioning units

o Landscaping materials

o Large quantities of wrapped and stackable products

WHAT INDUSTRIES USE FLATBED TRAILERS?

Because flatbed trailers have no enclosure, the freight they carry can be versatile and their use extends across several industries, such as;

o Housing

o Construction

o Renewable energy

o Agricultural

o Warehousing

o Manufacturing

o Mining and drilling

o Military

o Automotive

o Landscaping

WHAT ARE THE BENEFITS OF A FLATBED TRAILER?

There are several benefits to using a flatbed trailer for your freight. With a flatbed trailer, there is dimensional flexibility for loading or unloading freight since there are no physical walls or a ceiling to restrict its use. Any cargo that is oddly sized or irregular-shaped can be easily moved with a flatbed trailer. 

WHAT ARE THE DISADVANTAGES OF USING A FLATBED TRAILER?

When selecting the type of trailer your freight needs, you should know the disadvantages of each. Compared to traditional hauls, all flatbeds take considerable skill, effort, and time.

Since there are no physical walls to restrain freight, cargo securement and balance are two significant concerns with flatbeds. The FMCSA has a lengthy section in rules specifically for securement, as insecure cargo is a serious safety hazard.

Proper securement is needed for your freight too because if not done correctly, your freight can get damaged from the securement itself. Also, shipments often shift some during transportation, so even weight distribution and securement are necessary.

Another disadvantage to flatbed trailers is that there are no physical walls. It’s a positive for loading and unloading. Still, it can also be a negative as no enclosure means dealing with the elements (wind, rain, snow, sun, animal or human interference, truck smoke/smog, dust, and road debris). To combat this, there is the option of tarping your freight or using a Conestoga trailer.

There are even more significant risks and responsibilities with any oversized freight as these shipments have even more strict regulations to follow.

FLATBED SHIPPING TIPS

Know your cargo

Be sure to know all the details of your shipment. This includes commodities, value, dimensions, and weight. This information will help logistics providers know how to properly secure your cargo ahead of time. 

Understand what trailer you’ll need

Familiarize yourself with the different types of flatbed trailers before booking a shipment so you can make the most cost-effective and safe choice. Each type of flatbed trailer has certain limitations. For example, a specific flatbed trailer like extended trailers and Conestogas can be harder to find so your provider may need advanced notice when they are required.

Be aware of accessorial charges

Flatbed shipping may involve moving specialized loads which can need special equipment or extra services. Make sure you have the proper equipment and services needed for your freight to avoid extra charges, freight damage, or delays.

Choose to work with an expert

Arranging flatbed shipments on your own can be time-consuming and expensive, making sure all regulations are met and your cargo travels safely. Consider working with an expert in flatbed shipping to help secure capacity and locate the right equipment for your freight.

FLATBED RATES AND SEASONALITY

Freight shipping demand, which includes flatbed demand, is something that is often based seasonally. No matter the market, shipping rates fluctuate throughout the year and rise as the demand for freight rises.

Flatbed shipping is very closely connected to construction and industrial production, which can be highly dependent on the weather. These industries often slow down in the winter months, so normally, the demand for flatbed shipping will soften at the end of the year.

Smaller to medium-sized companies often slow down during winter and resume activity when warmer weather returns. However, larger companies are affected less by the seasonality and continue to move their commodities regardless of the time of the year.

Because of the seasonal rise and fall, you’ll find volume and rates lowest in the late fall/early winter, with the peak flatbed season being from April to October. This is when the volume of flatbed loads is highest, as are the rates.
