Fire Rated Steel Roll Up Door

The YUOU® aluminum alloy roll up door adopts high-strength aluminum alloy slats and a stable and reliable transmission structure design, taking into account structural strength, operational stability and long-term durability. Aluminum alloy material has excellent corrosion resistance and oxidation resistance, is not prone to rust, and is suitable for complex environments such as humid, rainy and coastal areas, effectively reducing maintenance costs.

Through a precise guide rail system, a reasonable interlocking structure of the slat and a dedicated motor configuration for roller shutter door, the door body operates smoothly, with low noise and uniform force distribution during the opening and closing process. YUOU® strictly controls materials and manufacturing details in accordance with engineering standards, providing reliable and durable aluminum alloy roll up door solutions for industrial and commercial buildings.

Structure Diagram

The Steel Fire Rolling Shutter Door Structural Diagram clearly shows its fire-rated construction and key components, helping you understand the door’s structure and working principle at a glance.

Door Slats

YUOU® steel fire-rated rolling door slats feature a 0.8mm double-layer galvanized steel plate structure filled with aluminum silicate rock wool fireproof insulation material, with an overall thickness of approximately 1.5cm. This composite structure ensures door strength and stability while significantly enhancing fire resistance and thermal insulation. It delays heat transfer during fire conditions, strengthening fire compartmentalization.

The double-layer galvanized steel plates offer excellent impact resistance and corrosion resistance. Combined with the internal fireproof filling layer, the slats maintain structural integrity even in high-temperature environments. This makes them suitable for industrial and commercial buildings with high requirements for fire resistance ratings and structural reliability.

Fireproof Motor

YUOU® steel fire-rated roll up doors are equipped with specialized fire-rated motors designed for heavy-duty door applications and firefighting scenarios. These motors deliver higher output torque and stable continuous operation. Featuring a robust structure and reliable transmission, they maintain stable performance in high-temperature environments and emergency conditions, meeting the reliability requirements for fire compartmentation.

This motor supports interlocking control with fire alarm systems. During a fire, it automatically receives signals and executes a downward action, enabling rapid response and secure isolation. It can also be configured with a manual emergency release device, allowing manual operation during power outages or emergencies. This ensures controlled access and enhances the overall safety and reliability of the fire protection system.

Electronic Limiters and Remote Control

The steel fire rolling shutter door is equipped with an electronic limit system for precise open and close positioning, preventing over-travel and protecting the motor and door structure. Optional remote control enables convenient and safe operation, suitable for industrial and commercial fire-protection applications.

Track and Reset Wheel

The steel fireproof roller shutter door uses thickened high-strength steel guide rails with excellent rigidity and deformation resistance, ensuring long-term stable operation. A sealing strip is installed on one side of the track to improve airtightness and help reduce noise. The guide rail is equipped with a reset wheel device to keep the curtain running smoothly and prevent deviation during opening and closing.

Hood Cover

YUOU® steel fireproof roller shutter doors are typically equipped with protective cover boxes to create a clean appearance and prevent dust from entering the roller and motor. The cover box is specially designed with a maintenance access opening for convenient inspection and servicing.

Advantages

The steel fire rated roller shutter door integrates certified fire resistance, strong structure, stable operation, and high cost-effectiveness for dependable fire protection.

Excellent Fire Resistance

The steel fireproof roll up door adopts a fire-resistant structure design. The door body material has excellent high-temperature resistance and flame-retardant performance, which can effectively prevent the spread of flames and high-temperature smoke in the event of a fire, forming a reliable fire compartment. Stable fire resistance can buy precious time for personnel evacuation and fire rescue, and meet the high standards of fire safety requirements for industrial and commercial buildings.

High Structural Strength, Overall Stability and Reliability

The door body is made of steel structure, which is highly rigid and has a high load-bearing capacity. Even in large-sized door openings or high-frequency usage conditions, it can maintain good structural stability. The stable door structure is not prone to deformation in high-temperature environments, which helps to maintain the integrity of the door in case of fire and ensures the long-term reliable fireproof isolation effect.

Interoperable Fire Protection System

Steel fireproof roller shutter doors can be linked with the fire alarm system. When a fire triggers the alarm signal, the door body can automatically perform a lowering or closing action to quickly form a fire isolation area. This linkage mechanism reduces the reliance on human operation, enhances the efficiency of emergency response, and makes the fire prevention system more intelligent and systematic.

Stable Operation

The steel fireproof roller shutter door has a mature structural design. Combined with a fireproof dedicated motor and a stable transmission system, it operates smoothly during daily opening and closing, with minimal mechanical wear and relatively controllable maintenance requirements. While meeting the fireproof function, it can also adapt to long-term usage scenarios and reduce the later operation and maintenance costs.
