Flatbed vs Curtain-Side Trailer: Which Should You Use?
Choosing the right trailer affects cost, loading speed and cargo safety. Here is how flatbed, curtain-side, lowbed and step-deck trailers compare.
Flatbed trailers
A flatbed has an open, flat deck with no sides or roof, so it can be loaded from the top, sides or rear — ideal for heavy machinery, steel, pipes and construction materials. The usable capacity depends on the specific vehicle, axle limits, cargo dimensions and route; confirm it for your load.
Because the deck is open, cargo must be properly secured and, when needed, tarped for weather protection.
Curtain-side trailers
A curtain-side combines the easy side access of a flatbed with the weather protection of a box trailer, using sliding fabric curtains. It suits palletised and general cargo that needs quick side loading and protection from rain and dust.
Curtain-siders are less suited to very heavy point loads or out-of-gauge cargo that needs crane loading.
Lowbed and step-deck
For tall or very heavy loads that exceed height or weight limits on a standard flatbed, a lowbed (or step-deck) sits closer to the ground — essential for equipment, transformers and abnormal loads that need oversize permits and sometimes escorts.
