EnglishWhat are the differences between fireproof glass doors and steel fireproof doors
Fireproof glass doors are made of fireproof glass, while steel fireproof doors are made of steel and fireproof materials. The materials used are different,
Advantages of steel fire doors:
The steel fireproof door is made of good cold-rolled steel plate or galvanized plate, color plate, stainless steel plate, etc., which is formed by cold processing (shearing, stamping, bending, etc.), then treated by pickling and phosphating, and then assembled by welding, internal biting, riveting, gluing and other processes.
The door frame is inlaid with fireproof expansion sealant strip, and the door surface is sprayed with fireproof paint and antirust paint. The door surface can also be sprayed with plastic and wood grain transfer according to the needs of users. The hardware shall be fireproof lock, fireproof door closer, fireproof hinge, handle, bolt and sequencer, and the corresponding grade of fireproof glass can also be equipped according to the needs of users. The performance of steel fire doors meets the requirements of national standards. The fire resistance time of fire doors is 1.2h, and that of class B fire doors is 0.9h. The size standard can be customized according to the customer's needs.
Advantages of glass fire doors:
1. Superior fire resistance
As we all know, the reason why the fireproof glass door can prevent fire must be that the glass door material has fire resistance. Good fireproof glass can still keep it from bursting for more than 90 minutes under the impact of fire up to 1000 ℃, which has won a valuable moment for people's escape and disaster relief work.
2. High strength
A fireproof glass door should not only have fire resistance, but also have high strength. For example, under the same glass thickness, the strength of fireproof glass is 6-12 times that of fluorinated glass and 2-3 times that of tempered glass.
3. Safety
In a fire, it is important that the fragments of good fireproof glass are in an obtuse angle after being broken, and its fragments are smaller than those of tempered glass, that is to say, even if it is broken, it will not cause harm to human body.
4. High weather resistance
Compared with the traditional grouting or composite sandwich fire-proof glass, the fire-proof glass has not only high light intensity, but also high weather resistance. Under the long-time irradiation of ultraviolet light, it will not have any change affecting the appearance and service performance, so it can keep transparent and bright for a long time.
