Our all aluminum trailers and truck bodies are one of a kind. Using 6061 T6 Aluminum in our patent-pending interlocking design; we build trailers and truck bodies with maximum strength and minimum weight. Every part of our trailer and truck body is designed to interlock together. After interlocking, each panel is huck-riveted and / or welded together to form walls, roofs and floors. Our walls, roofs and floors lock within our top and bottom rails which are also huck riveted. This monocoque / unibody construction creates a straighter, stronger more rigid product.
