A lot depends on what you want to get out of your trailer. Choosing the right flatbed trailer for you is going to depend on what you’re hauling, where you’re hauling, and how long you’re holding onto the trailer.
If you’re looking for something flashy, maybe an aluminum trailer is the way to go. But, if you want something to go to work, maybe you’re looking at a combo trailer. If you need something heavy-duty, an all-steel trailer could be right for you.
Aluminum flatbed trailers are typically your lightest option, lighter than steel or combination trailers, consisting entirely of aluminum – beam, side rails, and floors.
These trailers cost more than a combo and steel trailers, but on the upside, they do have a higher resale value.
Because aluminum deflects more than steel, these flatbeds are built with an arch (camber) in the trailer, which allows the beam to level as weight is added.
Combo flatbed semi-trailers are comprised of a steel beam, aluminum floor, and aluminum side rails. They provide the weight-savings of aluminum with the strength of the steel beam.
Combo trailers are less expensive than aluminum trailers and slighter more expensive than steel.
Steel trailers are built entirely of steel, including the beam, side rail, and suspension hangers, making them heavier than aluminum or combo.
They are a lower upfront investment; however, you won’t get as much on the resale value. It’s built to last and will be a good work trailer.

A curtainside trailer, or curtain van, is a dry van and a flatbed trailer combined into one trailer. It loads like a flatbed but protects like a van with a ceiling, front wall, and rear doors. The sides are open to allow access for loading, and the rear swing doors will enable it to be dock-loaded, similar to a dry van.
Curtains hang from the roof on each side of the trailer, slide open, and close to provide an enclosed trailer. On the Curtain side trailer, the frame does not move, and therefore top loading is not possible.
Curtain side trailers are an excellent option for loads that require more protection and special handling or when it’s more efficient to load from the side. It’s also a good option if you have multiple stops to make.

Aluminum trailers are lighter and less rigid than steel and flex a lot more than steel, so they’re built with an arch (Camber) to allow for flexing as the trailer flattens out when loaded heavily.
This arch might not be ideal for transporting long flat materials. Use dunnage racks to help fill that gap between the trailer’s arch and the product.
Space aluminum cross members closer together than steel cross members to support the additional weight from deflection, especially in applications where you’re rearing-loading with a forklift.

Combination and all steel trailers have less camber with the steel beam and, therefore, are flatter trailers.
Combination trailers typically include cross braces for additional support. The weight of the load is distributed through the cross braces and back to the steel beam itself.
Most flatbeds are not properly set up to back up to a dock with a forklift loading from the rear. Consider your cross member spacing and composition to help prevent those popping screws and waves in your floor.

If you are rear loading or have concentrated loads, we recommend decreasing your cross members to a maximum spacing of 12″ because aluminum cross members have more deflection than steel.
Steel cross members are stronger, so you can get away with spacing your cross members at 16″; however, you might still want to consider 12″ spacing.

It is important you need to understand how your trailer is spec’d and the load it’s equipped to handle.
A trailer with 24″ cross member spacing, and no side cross braces, should not be rear-loaded, and be mindful of the load toward the outside of the rail because the trailer is not set up to support the weight.
Available in steel, galvanized steel, low profile for use with toolboxes and drop decks, winches are a very common way to secure a load on a flatbed.
They can be mounted on the driver side, curbside, or both sides of the trailer. It all depends on your philosophy. For the driver, it’s easier to work with straps on the driver’s side; however, it’s safer to adjust your load from the curbside if you’re pulled off the side of the road.
You might consider load securement points on both sides for taller loads to help prevent the load from shifting. Utility has a proprietary side rail with the winch tracks built into it, allowing winches to be placed on both sides of the trailer.
Depending on the manufacturer, you may or may not be able to use a pocket to secure a load.
Spools working load limits (WLL) will vary depending on the manufacturer. Be sure to check with them to understand the pipe spools rating.
For example, wrapping a chain around one spool can have one rating, but the rating may change if you wrap it around two spools. The angle at which the chain comes off the spool will also determine the load limit rating on the spool.
Consult with the manufacturer for chain ratings. Also, check with the DOT for load securement regulations, tie-down requirements for heavy equipment, chain ratings, etc.
J-Hooks (Flatbed J Plates) are an adjustable load securement system used with flat hook straps or chains.
The J Hook plates slide into the tracks located on both sides of the deck, and can be placed anywhere along the track.

Due to the lower rear deck height, step decks can be a great option for hauling equipment, tall loads, and other cargo.
Generally, any load under 10 ft. tall and 8 ft. wide can be loaded onto a step deck trailer. Small loaders, skid steers, small excavators, or bulldozers are examples of equipment you can potentially haul on a step deck.
We recommend going with a Removeable Gooseneck (RGN) or a Lowboy for larger or heavier equipment. A Lowboy can carry cargo up to 12 feet high and heavier loads.
Step decks are an excellent option for hauling midsized equipment and provide the versatility to haul other loads.

Bulkheads are important to cargo control. They are affixed to the front end of a flatbed trailer to prevent forward movement of cargo and protect the driver carrying heavy loads.
There are two basic types of bulkheads for flatbed trailers, the wrap around and the flat.
Choosing the right bulkhead is important for both safety of the driver and the cargo. You want something durable enough to stand up to shifting cargo while not adding weight to your trailer.
Flat Bulkheads:

Many configurations are available depending on your needs, including bolt-on kits, steerable lift axles, and front and rear configurations.
Mount toolboxes between the spread axle or anywhere along the flatbed on either side.
A dunnage rack provides storage on your semi-trailer flatbeds for the wood (or dunnage) while transporting unpalletized loads.
They’re mainly used on flatbed, drop-deck, and gooseneck trailers to free up space on your trailer bed to allow you to carry more cargo.
And, they come in many styles and configurations, including baskets styles with or without a floor, side mounts, cross trailer mounts, and can be designed to hold dunnage as needed.

Morning, As I do not have all the details I cannot be definitive with an answer but I can say that with curtain sided 40' trailers we almost never loaded from the rear because it was quicker and safer to load from the side. We had two or three trucks feeding the trailer and the driver/mate would position the pallets on the trailer when the FLT had lowered them. Our trucks operated at ground level and did not go onto/into the trailer. The only time we loaded from the back was when we were putting in a couple of pallets and it was easier/quicker to open the back doors than to pull back the curtains. In 4 years we had 1 injury where a driver was on the ground (he was instructed to stay on the trailer till fully loaded) and claimed that he was hit by a reversing FLT, CCTV showed that he had been climbing on some very large plant and had fallen off hitting his shoulder. Just how do you envisage this operation being carried out, are the trucks going to deposit the load at the door or run down the length of the trailer. If the latter how do you know the trailer bed will support your FLT?
