This is an EU-standard certified insulated fire steel shutter (IFSS), holding dual certifications under BS EN1634-1:2014 and EN1634-1:2008. It offers fire resistance and thermal insulation ratings of 120 minutes (IFSS120) and 240 minutes (IFSS240), with the 240min rating being the world's first to obtain EU standard qualification, effectively stopping the spread of fire and high-temperature conduction in fire compartmentation areas of industrial and civil buildings.
It supports mid or side-mounted installation, driven by a fireproof motor with a maximum opening and closing speed of 0.12m/s. The door track is made of 3.0mm galvanized sheet or 3.0mm stainless steel plate. The door curtain is available in multiple configurations: EI120 57mm (1.0mm galvalume plate + fireproof filler + 1.5mm galvalume plate), EI240 105mm (1.0mm galvalume plate + fireproof filler + 1.5mm galvalume plate), with optional stainless steel versions (EI120 57mm / EI240 105mm), ensuring robust structural strength and heat insulation.
All materials are sourced from first-line large-scale steel mills, with a 20-year rust-free guarantee. A key safety feature is that when an alarm is triggered, the brake releases, allowing the shutter to close automatically under gravity.
Control options include manual push buttons and fire linkage, with optional safety devices such as temperature-controlled release and smoke/temperature sensors. Widely applied in industrial and civil building fire partition zones, this steel fire shutter delivers reliable fire protection, long-term performance, and compliance with EU safety standards, making it an ideal solution for various commercial and industrial facilities.
