Frequently Asked Questions

Q: What does the 3H fire integrity rating mean?

The 3H rating indicates that the fire shutter can maintain its structural integrity and prevent the passage of flames for up to 3 hours during a fire event.

Q: Which fabric option is best for high-radiation areas?

We recommend the Radiation-proof Cloth, which offers a vertical breaking strength of 867N and superior heat shielding properties.

Q: How is the smoke-proofing achieved in these shutters?

It is achieved through a high-precision guide rail design with a smoke-proof device covering 93% of the rail length and a low leakage rate of 0.05m3/(m2.min).

Q: Are the colors of the shutters customizable?

Yes, color options are optional and can be customized to match your architectural requirements or corporate branding.

Q: What is the difference between electric and self-weight drop speeds?

Electric opening/closing is driven by a motor (5.6m/min), while the self-weight drop (5.9m/min) is a fail-safe mechanism that triggers during power loss or fire alarms.

Q: How do these shutters handle heat transfer to the back surface?

The insulated design ensures the average temperature rise on the back surface remains ≤ 140℃, with a maximum peak not exceeding 180℃.
