DansnBAN is a joint brand created by Ambian and FireBAN, the leading brand of fire doors in the Middle East, aiming at building a stronger global brand of fire doors with the help of Ambian's outstanding technical barriers in the field of R&D and production of fire doors, and FireBAN's remarkable brand effect in the Middle East market and even in the global market, and striving to occupy 70%-80% market share of the Middle East and the GCC market in the next three years. In the next three years, we strive to realize the goal of occupying 70%-80% market share in the Middle East market and GCC, so that more safe and reliable fire doors can be landed to effectively protect the lives of the residents.


The difficulty factor of this type of fire door is extremely high, let us take stock of those highlights of Ambian American Standard UL 90-minute double-opening fire door with glass.


First: the door thickness is only 45mm


In general, the greater the thickness of the door leaf, the stronger the fireproof performance. In China, the thickness of 30-minute fire door is at least 45mm, the thickness of 60-minute fire door is at least 50mm, and the thickness of 90-minute fire door is at least 60mm, but our company breaks through the technical barriers through technological innovation, so that the thickness of 45mm double-opening fire door with glass can pass the UL 90-minute test, and it is thin, but it has high performance of fire door.


Second: glass inlay greatly increases the test difficulty


In general, more than 80% of the 90 minutes with glass fire door in the fire resistance limit test appeared in the fire or in the water test appeared in the phenomenon of penetration, so it can be seen that the fire door on the glass mosaic process requirements are extremely strict.


Third: double-opening fire door increases the test difficulty


Single-opening fire door fire surface is concentrated in the door door and door frame, and double-opening fire door door between the door to the mouth, is the weakest link in the fire door test link, the door to the mouth of the process of stopping the requirements are very high. In addition, double-opening fire door compared to single-opening fire door, the fire surface greatly increased, the larger the fire surface, in the test process, the door fan is more likely to appear deformation, sagging phenomenon.


Fourth: American Standard UL fire door test difficulty is harsh.


The national standard, British standard, European standard and Australian standard determine the integrity of the fire door is to go to the integrity of the standard for the ignition of cotton pads, the back of the flame and lasts for more than 10s or the gap probe can be passed through. However, in addition to the above mentioned standards, AFSL also takes the deformation of the door, i.e. the door and the movement of the surrounding deformation as the judgment standard. In addition, AFSL also requires the fire door to undergo water strike test immediately after passing the fire resistance limit test, which lasts for not less than 50 seconds, while the national standard, the British standard, the European standard and the Australian standard do not have this test item.


The successful passing of the test of 45mm American Standard UL 90-minute double-opening fire door with glass marks another breakthrough in the research and development, innovation and production capacity of our fire door products, and we also hope to contribute to the technological innovation in the field of domestic and even fire doors and to help the livable, safe and beautiful life.
