The Product Design and Application of Aluminum Alloy Fire Rated Sliding Door

Sliding door is a kind of door commonly used in households, which refers to the door that can be pushed and pulled. With the development of technology and the diversification of decoration methods, the materials of sliding doors have changed from traditional sheet surfaces to glass, fabric, rattan, and aluminum alloy profiles. The types range from sliding doors, folding doors to partition doors, and their functions and scope of use are constantly expanding, achieving functions such as sliding, translation, fire protection, observation, and partitioning.


The main structure of the aluminum alloy fire rated sliding doors is an installation frame formed by connecting the upper sliding beam, the first mullion, the sliding beam and the second mullion in sequence. A left sliding door and a right sliding door are arranged in the installation frame, and the upper sliding beam, the first mullion and the second mullion are located outdoors and indoors, and both sides are provided with first edge protection. The sliding beam is located on the indoor side with a second protective edge, and the sliding beam is located on the outdoor side with a drainage slope. Snap-type fireproof expansion strips are arranged on the first and second side guards, and the adjacent door frame surfaces of the left and right sliding doors are also provided with buckle-type fireproof expansion strips when they are closed.


Nowadays, the application of aluminum alloy fire rated sliding doors in daily life has become more and more common. Especially in some shopping malls, factories and other construction sites, due to the requirements of the installation environment, the performance of the sliding doors has also been improved, and it is necessary to have a fire protection function. In the fire rated sliding door, the fireproof performance is mainly achieved by penetrating the steel lining inside the sliding door profile and installing the fireproof expansion strip. When a fire occurs, the fireproof expansion strip will automatically expand to block the gap and block the air circulation between the two spaces. Thereby effectively preventing the hazards of heavy smoke, toxic gas and hot gas to the human body in the early stage of the fire and controlling the spread of the fire.
