When you lease a dry van trailer, its construction affects more than its exterior appearance. The materials used in its walls influence cargo handling and how well the trailer withstands daily wear. Understanding these differences helps you choose between aluminum and composite trailers based on your operation’s actual requirements.
Both construction types serve commercial fleets, but they respond differently to loading activity. The better option depends on how you plan to use the trailer and what conditions it will face.
How Aluminum and Composite Trailers Differ
Traditional aluminum dry vans typically use sheet-and-post construction. Vertical posts support thin aluminum exterior panels, creating a framework that has served the transportation industry for decades.
Composite trailers take a different approach. Their walls use engineered panels that combine multiple materials into a single structural component. Some designs bond a plastic core between metal skins, allowing the panels to provide structural support without the same interior post arrangement.
These differences influence the trailer’s available interior space and how it handles damage.
Compare Weight and Payload Capacity
Weight is a priority when you regularly transport heavy freight. A lighter trailer can leave more capacity for cargo within legal weight limits. However, aluminum construction does not automatically mean a lighter trailer. Modern composite designs also prioritize weight reduction, and some use engineered cores to remove unnecessary material.
Instead of relying on wall material, compare the empty weight of the available trailers. The floor system can influence that figure considerably, so review the complete specifications before deciding.
Consider Durability During Loading
Loading activity places repeated stress on trailer walls. Forklift contact, for instance, can dent thin aluminum sheets, particularly when operators work in tight spaces. Composite panels generally resist punctures and localized impacts better, depending on their construction. This can benefit operations that handle frequent loading cycles. Consider how often your employees load the unit and whether your cargo creates additional contact risks.
Understand Maintenance and Repair Differences
Aluminum sheet-and-post construction offers a practical advantage when damage occurs. Technicians can often replace individual sheets without rebuilding a large section of the trailer wall. Composite panels resist certain types of damage more effectively, but repairs require methods appropriate to their layered construction. A substantial puncture can involve more extensive panel work.
If your business plans to lease a trailer long-term, ask how the provider handles wall damage. Understanding maintenance responsibilities helps you plan for potential downtime.
Choose the Right Trailer for Your Operation
When choosing between aluminum and composite trailers, focus on what your business needs. Aluminum sheet-and-post construction offers an established design with straightforward repair options. Conversely, composite construction provides advantages in wall durability and interior space, particularly for operations with frequent loading activity.
