Fire Door Core Solution
| Application | Configuration principle |
|---|---|
| Door-leaf core layer | Select by leaf construction, target thickness and validated model; confirm bonding and lamination. |
| Reinforcement or inner lining | Coordinate board position and machining with face material, hardware layout and local openings. |
| Custom door-core composition | Confirm against the sample-door construction, fire target and applicable standard; do not substitute panel classification for complete-door validation. |
This solution is intended for fire-door manufacturers, door-core laminators, building-material buyers and distributors developing door products.
It explains the role of magnesium sulfate board within the door leaf and makes clear that an A1 panel does not by itself certify the complete door.
Will the board act as a core, reinforcement or inner lining?
How should board thickness coordinate with leaf thickness, hardware and finish?
Can panel test documents replace complete-door testing?
A1 Non-Combustibility
Fire-rated material classification for enhanced building safety.
Ultra-Low Chloride Content (≤0.01%)
Ensures corrosion resistance and long-term durability in door constructions.
Formaldehyde-Free & Asbestos-Free
Healthier indoor air quality with safe handling during fabrication.
Versatile Core Application
Suitable as core, reinforcement, or inner lining within fire-door leaves.
Door type, total leaf thickness and board position
Target fire requirement and applicable standard
Face material, bonding process and pressing conditions
Hardware layout, openings, cutting and edge-machining requirements
Test reports, certificates and production evidence shown externally should correspond to the actual product model, specification and test conditions. This solution page provides basic evidence and does not use unrelated certificates to infer complete-system performance.
With the currently available materials, evidence of real production, finished-product inspection and principal certificates is sufficient. Detailed test data can remain on the relevant product or quality-certification page.
