Description

Technical Field

[0001] This utility model relates to the field of fireproof rolling shutter door technology, specifically a steel fireproof rolling shutter door. Background Technology

[0002] Fire-resistant roller shutters are fire-resistant and heat-insulating facilities suitable for large openings in buildings. Common types of fire-resistant roller shutters include steel fire-resistant roller shutters, inorganic fiber composite fire-resistant roller shutters, and extra-high-grade fire-resistant roller shutters. Fire-resistant roller shutters are widely used in fire-resistant partitions in industrial and civil buildings. Extra-high-grade fire-resistant roller shutters, in addition to fire resistance integrity, also have heat insulation and smoke-blocking properties. They can effectively prevent the spread of fire and protect the lives and property of the public. Therefore, during the acceptance process, the installation, control and feedback, and emergency stop escape functions of fire-resistant roller shutters should be the focus of inspection.
