A sturdy, rectangular door constructed from welded sheet metal panels, featuring a flat, smooth surface with visible weld lines along the edges. The door has a simple, utilitarian design with a small, reinforced window at eye level, covered by a sliding metal shutter. The handle is a robust, metal lever, and the hinges are large and exposed for durability. The overall appearance is industrial and functional, with a matte, slightly weathered finish to suggest use in harsh environments.
