The fire resistant sliding doors are made of a series of panels manufactured with a compound of materials allowing it to isolate the fire and to keep the integrity for a minimum time of 90, 120 or 180 minutes, depending on the model chosen.
The panels are joined together by an exclusive system of Angel Mir that enables them to withstand the high temperatures of a fire without become deformed, and they perform to fire exposure on both sides. These panels are guided on the top by galvanized steel rails and on the ground by a bearing through which runs the sheet. By combining different thermal insulating materials, the passage of flames and gases through the joints can be avoided.
In case of fire, the locking of the fire resistant sliding doors is automatic. This happens by means of a counterweight which is released through an electromagnet that must be connected to the fire central or to an authorised detection system. The finishing of the sheet is lacquered in white and the rest of the profiles in galvanized steel. It can be manufactured in stainless steel for the industries that may require it.
