Steel fire doors are widely used in buildings, mainly as an important fire fighting equipment in buildings, and also an important part of social fire prevention. In order to ensure the use of fire doors, fire door closers can naturally be installed, and of course, closing devices can also be installed to automatically close the normally open fire doors in the event of a fire. It is common to install door closers on fire doors, except for some special parts (pipe shaft doors). Next, let's introduce the structural materials and characteristics of steel and wood fire doors.

Structural materials of steel fire doors: 1. Wooden fire doors include all-steel fire doors and steel fire doors, and the material is slightly different. 2. The door frame, door frame and door panel of the steel fire door are made of steel. The door is filled with non-toxic and harmless fireproof insulation materials, and then fireproof hardware accessories are used as connectors and fasteners to form a steel fireproof door with excellent fire resistance. 3. Steel and wood fire doors are made of steel and flame retardant wood materials, such as door frames, door frames and door panels, and the interior is also filled with fireproof materials. The steel fire door not only has excellent fire insulation performance, but also has strong decorative effect. Fire door manufacturers produce a lot of fire door styles, novel and fashionable, won the favor of customers.

Type: steel anti-theft door core, environmental protection, flame retardant, heat insulation, fireproof composite panel, foreign secondary patents, molding finishes. Based on the unique advantage of relying entirely on the fire resistance of the sheet itself without the need for traditional process fillers, the combined workshop design is possible. The inner and outer door panel and the inner and outer door line can be removed after hanging, the door frame adopts the overall on-site assembly and installation structure of accessories, the frame material is standardized and removable, the accuracy is high, the installation and transportation is convenient, which not only solves the problem of fire break bridge, but also achieves a new decorative effect
