Features of fireproof rolling door

DOORS with modern features are used increasingly widely. Technology latest DOORS production has now formed for the fireproof rolling door products have many outstanding properties beneficial to the user Vietnam.

1.Material of Doors Ngo Nguyen

Doors are made of steel, stainless steel alloys can withstand high temperature effects in a long time constraints and mitigate fire damage caused to humans. At the same time the door was secure network resources and assets for us.

2.Constructed of Doors Ngo Nguyen

* Body shop
Made from galvanized steel spokes 1.2 mm thickness and 20kg standard weight / m2.Cua hot dip galvanized or painted with enamel baked polyester coating. If rising temperatures on the surface painted spokes puffed, volume expansion, coal chemical and natural gas emits fire extinguishing. Doors can withstand temperatures from 1000 - 1500 ° C refractory period depending on the material and structure of the door.

* Bottom
Made of alloy steel regular size 38 x 38 x 3 mm or 40 x 40 x 6 mm and they are designed depending on the area of the door. Bottom bar balancing effects of gravity for the body shop.

* Box covered rollers
Each box of rolling door cover steel frame and covered 7mm thick galvanized coating has a thickness of 0.8 mm.

*Ray navigation
Ray has shapes with a thickness of about 3mm ensure rigidity for smooth door operation.

* Balance springs system
The system put in effect roller supporting springs cua.Cac body is designed to meet the 25% safety factor to the door loading operation safer.

* Motor Voltage: Often used the following voltages: 110V 60 Hz 1 phase; 220V 1 phase 60 Hz; 1-phase 230V 50 Hz; 400V 3 phase 50Hz

3.Operation of fireproof rolling door
When incidents occur timer control box and operate the door quickly. Now deceleration mechanism is activated from the fire alarm system. Doors also the heat and smoke detector to receive the signal and provide power to the motor controller gradually lowered gates to isolate the fire place from 2 to 4 hours.

4.Advantages of fireproof rolling door
- Doors can close during the explosion occurred. Safety and convenience even when disconnected from the mains.
- Operating softly, softly.
- Door with open hand in an emergency.
