Environmental And Health Requirements Upgrade
Traditional fire door filling materials may release harmful gases, while new standards and green building codes impose stricter limits on formaldehyde and flue gas toxicity.
Key considerations include: whether environmentally friendly inorganic filling materials (such as formaldehyde-free perlite boards or eco-friendly magnesium-silica boards) are used, and whether flue gas toxicity test reports are provided.
Intelligentization And Widespread Adoption Of Continuously Open Technology
Intelligently linked fire doors (interconnected with fire alarms and evacuation indicators) are increasingly being adopted in large commercial complexes, hospitals, and high-end residential buildings.
The normally open fire door, when combined with a release device and door closer, maintains easy access in normal operation and automatically closes during a fire—reducing the risk of human-induced failure due to closed-door operation.
Key points: System compatibility, emitter stability, and automatic shutdown function after power failure.
Stricter Authentication And Traceability Systems
Relevant certification has been converted to mandatory self-declaration plus supervisory sampling inspections, resulting in a reduced market space for counterfeit and substandard products, though such products still persist.
The new "one item, one code" traceability system has been widely adopted, allowing users to scan the QR code on the door panel to retrieve information such as the manufacturer, fire resistance rating, and inspection reports.
Recommendation: Prioritize suppliers that provide complete traceability information and enable on-site QR code verification.
