Heavy-duty truck doors vary significantly depending on the exact location of the door and the type of vehicle. For commercial vehicles, they generally fall into three main categories:

1. Semi-Truck Cabin Doors

These are traditional, rigid hinged doors built for major heavy-duty commercial truck cabs. They ensure cabin structural integrity, weather protection, and driver comfort during long hauls.

2. Box Truck & Trailer Roll-Up / Overhead Doors

Used primarily for delivery vehicles, dry vans, and transport trailers to maximize safety and speed during loading without swinging open into traffic.

3. Service Body & Work Truck Compartment Doors

Smaller, heavy-duty access doors built onto service utility beds, emergency response vehicles, or toolboxes.
