Folding Doors

Introduction

In situations where a door installation is necessary for large opening dimensions and where additional roof loading is not an option, Entrex solution offers the ideal solution with its in-house manufactured folding doors. Our folding doors provide significant advantages in terms of operation. These doors are fully automatic but can also be operated manually in the event of a power outage. They can be installed in a variety of opening sizes. Requiring less back run, folding doors take up less space for parking, offering a clear opening and reducing the risk of accidents. Available in both single and bi-parting options, with puff insulation and other features, our folding doors come in a wide range of configurations with remarkable variations. Constructed from strong metal surfaces, these doors act as a shield against extreme weather conditions. With various safety and signaling accessories integrated into the design, our folding doors are safer, more durable, quieter, and offer easy operation.
