Our single-sided door features a steel plate on the front face only, with hat-channel reinforcements on the reverse side to prevent warping. This design maintains structural integrity while offering lightweight construction and ease of installation. These doors are ideal for utility applications such as meter boxes and pipe access areas. Fire-resistant versions are available, engineered based on comprehensive fire testing. Although our calculations reference standard dimensions (900mm width × 2100mm height), all products can be custom-designed to suit specific applications and opening specifications.
