What Is Step Deck Equipment in Trucking?
Step deck equipment, also known as drop deck trailers, is a specialized type of flatbed trailer used in trucking to transport tall or oversized loads. Unlike standard flatbeds, step deck trailers have two levels: a higher front deck and a lower rear deck. This design allows for taller cargo to be hauled legally under bridge clearance regulations while maximizing load flexibility. Step deck trailers are commonly used in industries such as construction, manufacturing, and heavy machinery transport.
Types of Step Deck Trailers
There are two main types of step deck trailers:
- Single-Step Deck
This is the standard step deck trailer, featuring a higher upper deck near the truck and a lower main deck behind it. It allows for carrying taller cargo that wouldn’t fit on a regular flatbed while maintaining road clearance. - Double-Step (or Extendable) Deck
Some step deck trailers have an extendable lower deck that can accommodate longer loads. These are ideal for oversized or unusually shaped freight like construction beams, large machinery, or industrial equipment.
Dimensions and Load Capacity
A typical step deck trailer is about 48 to 53 feet long, with a deck height of 39 inches for the upper deck and 31 inches for the lower deck. Weight capacity generally ranges between 40,000 and 48,000 pounds, depending on the trailer and truck configuration. This makes step deck trailers suitable for heavy and bulky freight that cannot be transported with standard dry vans or flatbeds.
Benefits of Using Step Deck Equipment
- Allows taller cargo: The lower deck height provides extra vertical clearance, so freight that exceeds standard flatbed height can still be transported legally.
- Versatile for many industries: Step decks are ideal for construction materials, industrial equipment, steel coils, machinery, and other oversized freight.
- Maximizes load efficiency: The two-level deck allows shippers to organize cargo more efficiently, sometimes carrying more volume in a single load.
- Improved safety and stability: Heavy or tall items can be loaded lower to the ground for better balance during transport.

Common Industries That Use Step Deck Trailers
- Construction: beams, trusses, scaffolding
- Manufacturing: heavy machinery and equipment
- Oil and Gas: large tanks, pumps, and generators
- Steel and Lumber: coils, sheets, and boards
Step Deck vs. Flatbed
While both step deck and flatbed trailers are used for open freight, the key difference is height clearance. A standard flatbed is ideal for most general loads, but step deck trailers are necessary when the cargo is too tall for a regular flatbed to pass under bridges or comply with road regulations.
Final Thoughts
Step deck equipment is essential for hauling tall, heavy, or oversized freight safely and efficiently. Drivers, carriers, and shippers who deal with construction materials, machinery, or industrial goods often rely on step deck trailers for their flexibility and load capacity. Understanding how step deck trailers work can help trucking professionals maximize their operational efficiency and revenue potential.
