wabash duraplate HD trailer

Introduced in 2003, the DuraPlate HD® provides best-in-class strength and durability. The high-strength aluminum base plate in the lower sidewall withstands the most abusive freight hauls and resists damage from exterior sideswipes. This model is ideally suited for both general freight and heavy-haul freight such as paper, automotive parts and carpet.


(1) ID/Aux Stop Light System

The new ID/Stop Light System integrates auxiliary brake light indicator functionality with the upper rear ID lights – providing better visibility of trailer braking.

(2) DuraPlate Doors with the TrustLock Plus System

Lightweight and extremely durable, DuraPlate composite swing doors resist corrosion and impact damage to lower your maintenance costs. Swing doors come standard with our proprietary TrustLock Plus System. DuraPlate overhead door designs are also available.

(3) Top Rail Connection

Unlike other composite plate trailer designs, our top rail connects to the exterior of the trailer sidewall, eliminating potential and significant leak points.


(4) DuraPlate Composite Plate Sidewalls

DuraPlate panels are constructed of a high-density polyethylene core bonded between two high-strength steel skins to provide unmatched damage resistance and maximum interior width. DuraPlate sidewall panels are made in the U.S.A. and backed by a 10-year warranty.*


(5) High-Strength Floor System

Rated at 20,000 lb., our full 1-3/8” oak floor system with bolted crossmember connections provides superior floor strength to support high-cycle loading/unloading and extends floor life. Floor systems with higher load ratings up to 28,000 lb. are available.

(6) Heavy-Duty Base Plate

22” high aluminum base plate eliminates the need for an interior scuff liner and provides unmatched resistance to interior and exterior damage.


(7) Stainless Steel Lower Nose Rail

Heavy-duty, stainless steel lower nose rail with approach angle resists damage and corrosion in this high-impact area.
