Doors developed gradually from skins hung across openings, slabs of stone that pivot on metal pins, to great wooden slabs, then more stylised doors made of wood. Doors sheathed with metal were more secure and were harder to break down. They also had the added benefit of retarding fire for a little while - more than doors made only of wood. Commercial steel doors offer more security as well as can be rated for fire, offering the best protection and security of all.
Commercial steel door
A building supply store will have some commercial doors - especially stores that cater to a professional clientèle more than just the Harry Homemaker. The doors will come in various colours and configurations. Some of the doors may have fire glass or custom glass (which you may have to special order). The doors may have fire ratings that range from A to D - A is able to hold back fire and smoke for three hours and the D rated doors have only a 1.5 hour rating.
Commercial door companies
Stores that specialise in commercial steel doors will have a wider selection of doors than at building supply stores. These doors will be hinged doors, security shutter doors, roller shutters and overhead doors. These doors will also have fire ratings and have a variety of finishes. Some doors may also come as part of door systems which helps to increase the integrity of the door and supporting the fire rating. These industrial doors will work well in any business, hospital or industrial building.
Custom doors and lock systems
Perhaps you have a business or a building that has unusually sized door openings. Having a commercial steel door built to specifications will be necessary. Commercial door companies that manufacture doors to order will be necessary. These doors can have fire-rated glass as well as other details that you require. If you have the need for added security, then companies that make commercial doors with various locking systems can be purchased. The locking systems can have secure keyed locks, combination locks, key pad locks or even more advanced locks. By specifying what you need as far as the door's construction and the lock set are concerned, custom door companies will be able to work with you to provide you with what you need.
