Reasons to Buy Diamond C

Engineered Frames

Engineered Frames

Unlike most trailers made with commonly used structural steel, Diamond C's engineering team has taken their products to another level by carefully designing and fabricating custom beams for all of their heavy-duty trailers (GVWR 16,000+).

Difference Maker Powder Coating System

One of the most common complaints from trailer owners is the paint durability on their steel trailer. Diamond C took a unique approach in designing their coating system to produce the best possible product for the user, not just the cheapest way to put paint on a trailer. They also offer a wide selection of colors, with custom colors available upon request.

Say goodbye to loose wires and traditional butt splices. Diamond C partnered with USA Harness Engineering to create an automotive grade wiring harness that is custom to each model and length. The plug-and-play design removes human error and allows for easy modifications when adding accessories.
