Modern architecture increasingly demands fire protection solutions that go beyond standard rectangular openings. The Irregular Shaped Fire Resistant Rolling Shutter is specifically engineered to meet this challenge, providing reliable fire barriers for curved, angled, or geometrically complex spaces where conventional vertical or horizontal shutters cannot be installed.
Key Features
Exceptional Shape Adaptability
This system can be custom-fabricated into a wide variety of configurations, including U-shaped, C-shaped, L-shaped, O-shaped, S-shaped, and V-shaped layouts. Whether wrapping around an escalator opening in a shopping mall, following a curved corridor in a museum, or sealing an odd angled atrium in an exhibition center, the shutter conforms precisely to the architectural design without compromising safety.
High-Performance Fire & Smoke Protection
Fire resistance: Certified ≥4 hours, with back-face average temperature rise ≤55.6°C and single-point maximum ≤63.6°C – far below the 140°C standard. This allows the shutter to act as a true firewall without any water curtain protection.
Smoke sealing: Leakage rate ≤0.2 m³/(m²·min) at 20 Pa differential pressure, effectively containing toxic smoke.
Double-track, double-curtain construction using inorganic fire cloth, aluminum silicate fiber blankets, and radiation-resistant fabric, reinforced with galvanized steel strips and high-temperature stitching.
Manufacturing Process
All our Irregular Shaped Fire Resistant Rolling Shutter are produced under strict quality control systems, fully complying with China's GB 14102-2005 standard and relevant international industry specifications.
Raw Material Inspection and Preparation
All raw materials, including inorganic fireproof cloth, aluminum silicate fiber blankets, radiation-resistant fabric, decorative polyester fabric, galvanized steel strips, stainless steel wire ropes and high-temperature sewing threads, undergo strict incoming inspection. Every batch of materials passes professional burn-through resistance and tensile strength tests before entering production.
Curtain Integrated Fabrication
The multi-layer composite curtain is assembled on a large precision sewing platform. Materials are laminated in standard order: optional decorative fabric, radiation-resistant fabric, aluminum silicate fiber blanket and outer fireproof cloth. Stainless steel wire ropes are embedded at fixed intervals to enhance overall tensile strength. The laminated layers are integrally sewn with high-temperature resistant threads via professional industrial sewing equipment. Galvanized steel strips are clamped on the edges and middle positions of the curtain to keep it flat and rigid.
Horizontal Roller and Track System Processing
The core horizontal roller adopts high-strength seamless steel tube as raw material, processed by precision machining and dynamic balancing treatment to avoid shaking during operation. It is fitted with high-precision bearings and dedicated gearboxes. The top and bottom double tracks are roll-formed from galvanized steel and equipped with integrated smoke sealing strips. For curved and special-angle installation scenarios, tracks are custom bent and shaped by CNC bending equipment to fit on-site conditions.
Drive and Control System Assembly
A dedicated low-noise motor with an electromagnetic brake is connected to the roller through chain transmission or direct drive. The supporting control panel is equipped with a PLC programmable controller, which reserves interfaces for smoke/heat detectors, manual control panels and building fire alarm systems. Manual chain hoist and thermal emergency release devices are standard safety backup configurations to ensure reliable operation under abnormal conditions.
Overall Assembly and Strict Performance Testing
The finished curtain, roller, drive unit and track components are assembled on a professional test bench for comprehensive performance tests, including:
Operating speed calibration (ensuring 2–7.5 m/min powered operation)
Gravity self-lowering speed test (controlled within 9.5 m/min)
20 Pa differential pressure smoke leakage test
4-hour+ furnace fire resistance test with real-time temperature monitoring on the non-fire surface
10,000-cycle mechanical endurance test to verify long-term operational stability
Standardized Packaging and Delivery
After passing all performance and safety tests, the finished products are disassembled into modular parts including curtain rolls, track sections and drive units for safe and convenient transportation. Each set of products is delivered with complete installation manuals and official certification documents.
Ideal Applications
This shutter excels in large span, irregular spaces such as shopping mall escalators and atriums, airport terminals, theater stages, convention centers, museums, and any location where standard fire shutters cannot be installed. It combines uncompromising safety with architectural freedom.
