Currently, there are two popular types of fire-resistant, heat-insulated hatches (fireproof hatches): fire-resistant steel rolling doors and fire-resistant heat-resistant rolling shutters.

• Steel structure fireproof rolling door: Has a steel slat structure with extremely superior fire resistance. In particular, the product can ensure security and prevent intrusion very effectively.
• Heat-resistant fireproof rolling doors: Designed to be made from fire-resistant and heat-insulating materials. The product has a lighter density than steel slats, costs less and is rolled up and hidden on the ceiling. When there is a fire alarm, the canvas curtain will automatically collapse and meet the fire prevention and insulation requirements of fire protection.

Operating principle of rolling fire doors

During operation, when a fire starts, the fire trap door/fireproof rolling door will automatically have a warning bell through the smoke sensor system and fire sensor system and then begin to release the door. This way toxic smoke and fire from the fire area will be prevented from spreading outside.

Because the door will have an automatic closing mechanism to block toxic smoke and spread the fire further, within a period of 2 to 4 hours, the user can promptly extinguish the fire. At the same time, people can promptly evacuate, protecting human life and property.

However, while the door is in operation, it is necessary to pay close attention that no one is allowed to stand or walk under the door. At the same time, to prevent the limit switch from being damaged, the shutter jamming, the motor being clogged or having other problems, fireproof, insulated hatches (fireproof hatches) should not be used frequently. Only then can the door be put into effective use when a fire occurs.

Besides, to avoid abnormal situations, the door should be set up with a regular maintenance system. You should keep a record of the maintenance of each hatch to facilitate future tracking. Ideally, fireproof rolling doors should be inspected and maintained every 6 months.

Maintenance content is usually dust removal and lubrication of sprockets and rollers of transmission parts. Then check the wiring and electrical equipment for damage. Especially whether they operate normally and comply with instructions. If there is a problem, it needs to be repaired and troubleshooted immediately to have a standard fire door solution.
