When it comes to hauling oversized, tall, or heavy cargo across the U.S., not just any trucking company will do. Step deck (also known as drop deck) trucking companies specialize in transporting freight that exceeds the height limits of conventional flatbeds. Because of their niche expertise, selecting a trustworthy, experienced provider is vital. In this blog, you will discover what step deck trucking is, and get to know 10 top U.S. step deck trucking companies you can count on. We’ll also explore the benefits of using step deck services and wrap up with tips to choose the right carrier.
What Is Step Deck Trucking?
A step deck trailer (or drop deck trailer) is designed with a deck that drops lower after the gooseneck portion, giving extra vertical clearance for taller cargo. In other words, while a standard flatbed trailer maintains a uniform deck height, a step deck gives an extra “step down,” enabling it to haul taller loads without exceeding legal height limits.
This configuration allows shippers to move machinery, large equipment, oversized structures, or materials that would otherwise need costly permits or special arrangements on a flatbed. Step deck trailers can come in lengths like 48 ft or 53 ft, and often they carry loads up to the legal weight limits for highway transport.
Because of the complexity of securement, permitting, and routing for tall or wide freight, companies that specialize in step deck trucking typically build experience and systems to handle those challenges.

Benefits of Using Step Deck Trucking
Leveraging step deck trucking offers several advantages for shippers:
-
Greater Vertical Clearance
The dropped deck design lets you haul taller cargo without overly increasing the height. This lowers the need for special permits or customizing the load. -
Cost Efficiency
Since the design reduces the need for extensive over-height permitting or alternate routing, step deck transport can be more economical than rerouting oversized loads entirely. -
Versatility
Step deck trucks can handle a broad range of freight — from machinery to structural steel, large tanks, industrial equipment, and more. -
Reduced Load Restrictions
Some loads that can’t fit on flatbeds due to legal height limits are easily accommodated on step decks, reducing the need for disassembly or special handling. -
Integrated Permitting & Routing Services
Specialized step deck carriers often provide assistance with permitting, route planning, escort services, and driver training — ensuring safe, compliant delivery. -
Better Safety and Securement
Experienced step deck providers understand the securement needs for taller cargo, including tie-downs, bracing, and stabilization to prevent load shift. -
Reliability and Expertise
Choosing a reputable step deck carrier ensures you have professionals managing the complexities of oversize transport, reducing the risk of delays, fines, or cargo damage.
