Also searched as fire shutter, fire-rated rolling steel door and compartmentation roller shutter.
A fire rated roller shutter door that closes off a fire compartment on alarm or power loss. Interlocking galvanized steel slats, gravity fail-safe descent and EI60 / EI120 capability engineered per project — built to your opening, from prototype to full production runs.
One idea: an opening that stays open in normal use and becomes a rated fire barrier the moment the alarm triggers — without a swinging leaf that blocks aisles or a fixed wall that kills the floor plan.
A fire rated roller shutter door is an active compartmentation barrier. It parks overhead out of the way during daily operation, then descends automatically on a fire-alarm signal or on power loss to close the opening and hold back fire and hot gases between two compartments. Because it rolls, it suits wide openings where a hinged fire door would be impractical.
RAX manufactures each shutter to your exact opening from interlocking galvanized steel slats, with a gravity fail-safe descent as the default life-safety behaviour. The fire class — EI60 or EI120 — is engineered and confirmed per project against the matching test standard for your installed size and configuration, not sold as a standing off-the-shelf certificate.
Fire rating EI60 / EI120 is a per-project manufacturing capability confirmed against the matching fire-resistance test standard for your configuration; it is not a held stock certificate. Cycle life of 100,000 cycles is validated in the RAX fatigue test lab.
Every shutter is engineered to your opening. The values below are the validated baseline; final figures are confirmed on your specification. Each row states whether the value is RAX-measured, an industry-typical range, or per project.

Need a fire class evidenced for tender? We arrange the matching fire-resistance test data per project — see Compliance below for what is held versus arranged per project.
Validated substrates, processed in-house on a CNC punching / bending centre. No outsourcing of the structural parts.
Wide openings that must stay open in daily use yet close into a rated barrier on alarm.
Your installers get the full document set before the shutter ships — the same package our fire contractors and EPC clients rely on.
Certificates we hold today, and the project-specific fire test data we arrange against the matching standard. We state held versus per-project so fire contractors can tender honestly.
Rigorous 100,000-cycle fatigue testing, validated galvanized steel materials, and precision manufacturing — performed in-house, with the fire class arranged per project against the matching standard.
Large industrial doors from prototype to container-load delivery. Start with an OEM sample and scale to container-load branded production.
Every fire shutter is built to your opening and your project spec. Send the clear opening size, the required fire class and the control integration (or site photos) and our engineers return a proposal, technical confirmation and lead time.
From custom engineering to container-load delivery — the document set your local installers need.
Warranty: door body 2 years · operator/motor 3 years · servo motor 5 years. Free spare parts within warranty (DHL/FedEx 5–7 days). Lead time: sample 7–15 days · standard container 12–20 days · custom first order 20–35 days.
EI is a fire-resistance classification: E stands for integrity (resisting flame and hot-gas passage) and I for insulation (limiting the temperature rise on the unexposed face). The number is the duration in minutes, so EI60 holds both criteria for 60 minutes and EI120 for 120. RAX offers EI60 and EI120 as a manufacturing capability — the specific class for your project is confirmed against the matching fire-resistance test standard for your installed size and configuration.
The shutter uses gravity fail-safe descent as standard: it releases and closes automatically on a fire-alarm signal or on power loss, with no manual intervention. An optional battery or UPS backup provides a controlled descent where a gravity-only drop is not suitable. This is the core life-safety behaviour fire contractors expect from a compartmentation shutter.
Yes. The control panel interfaces with standard fire-alarm panels, smoke and heat detectors and building management systems. It is pre-wired and function-tested before dispatch, with wiring diagrams included in the document set. Optional RS485 communication adds remote status feedback and monitoring.
Yes. Every shutter is engineered to your clear opening width and height, or from site photos. Every order is custom-manufactured, so you can buy a single shutter built to a non-standard size, in any RAL colour. Our engineers confirm the feasible span and produce a technical proposal for approval before production.
RAX holds ISO 9001:2015, CE marking against EN 13241 (industrial door product standard) and EN 12453 (operator safety), plus SGS material reports and Product Liability Insurance. The fire rating (EI60 / EI120) and AS/NZS 4505 / UL counterpart test data are arranged per project, not held as standing certificates.
Sample orders run 7–15 days, a standard container 12–20 days, and a custom first order 20–35 days (repeat custom orders 15–20 days). FOB ports are Tianjin and Qingdao; FCL and LCL are both supported.
Every order includes wiring diagrams, an English installation manual, FAI first-article confirmation and pre-assembly photos, a factory inspection report (speed, noise, insulation resistance, visual), the 100,000-cycle fatigue test video/report, and the CE Declaration of Conformity with the EN 13241 test report.
Send your opening size (W × H), the required fire class and the control integration. Our engineers reply with a proposal and lead time — no obligation.
