The steel fireproof rolling shutter door is an advanced product designed for safety and durability. It features a curtain made from hot-rolled galvanized sheet, with a core filled with high-performance fire-resistant and heat-insulating material. This construction ensures a smooth and aesthetically pleasing appearance, while offering excellent structural strength, tight sealing, and reliable fire resistance. Additionally, it combines both mechanical and electrical functions for enhanced performance.
The flexible panels are connected in a series, allowing the shutter to move smoothly and swing up to 90 degrees without falling off. The steel baffle shutters at both ends or the anti-tampering mechanism are securely assembled to ensure stability during operation. When the shutter is moving, the adjacent panels should not shift more than 2 mm, maintaining a tight and consistent structure.
When fully assembled, the steel fire shutter must remain straight, with no holes or gaps allowed. These specifications ensure its effectiveness in fire protection scenarios.
