fire door
A fire door serves as a barrier to limit the spread of fire and restrict the movement of smoke. Unless they are held open by the automatic systems, fire doors should remain closed at all times. Do not tamper with fire doors or block them with equipment, potted plants, furniture, etc.Fire doors are normally located in stairwells, corridors, and other areas required by Fire Code. The door, door frame, locking mechanism, and closure are rated between 20 minutes and three hours. A fire door rating indicates how long the door assembly can withstand heat and a water hose stream.Always keep fire doors closed. If it is necessary to keep a fire door open, have a special closure installed. This closure will connect the fire door to the building’s fire alarm system, and will automatically close the door if the alarm system activates.

Steel fire door custom made to suit existing structural opening for use as security, escape and personnel.
Double doors are fire rated for four hours and single doors for six hours. Both door-sets can have glazing and still carry the same certifications.A choice of flush, lipped or double lipped is available at the same price. Door leaves are manufactured from 1.2, 1.6 or 2.0 Zintec steel, double skinned with interlocking seams reinforced vertically with interlocking channels and horizontally with tubes to prevent twisting.Spaces are filled with dense Rockwool. As an option you can have a honeycomb filled leaf which is still as strong and rigid as a Rockwool filled leaf but is very much lighter. This is a better option if powder coating is required.Standard thickness is 45mm, but any other thickness is available on request.
