Premium fire door core material supplied directly to fire door manufacturers worldwide. Certified FD30/60/90/120 fire performance, consistent density, dimensional stability, and excellent machinability for large-scale door production.
Modern fire doors are life-safety products required by building codes in commercial, institutional, and high-rise residential projects. The door core material is the critical component determining fire rating performance — typically FD30 (30 min), FD60 (60 min), FD90 (90 min), or FD120 (120 min).
HR RHINO supplies premium calcium silicate boards as fire door core material to fire door manufacturers worldwide. Our boards meet the strict requirements of door production: A1 non-combustible classification, consistent density across every batch, precise dimensional tolerances, and excellent machinability for CNC routing, edge banding, and hardware installation.
Whether producing timber fire doors, steel fire doors, or composite doors, our boards deliver the fire performance, sound reduction, dimensional stability, and production-friendly handling that fire door manufacturers require. OEM cutting services and custom thicknesses available for large-scale production.
Our calcium silicate boards are used as core material across all fire door types and fire resistance ratings.
Entry-level fire doors for residential apartments, hotel guest rooms, small office partitions, and escape routes. Most common fire rating in residential and hospitality projects worldwide.
Standard commercial fire doors for offices, shopping malls, schools, hospitals, and stairwell entries. The most widely specified rating for commercial buildings, meeting most building code requirements.
Enhanced fire doors for high-risk areas including electrical rooms, data centers, chemical storage, and critical infrastructure. Higher density cores and thicker construction required for extended fire performance.
Premium fire doors for maximum fire protection in high-rise buildings, stairwells, fire-fighting shafts, elevator lobbies, and explosion-risk areas. Demands highest quality core material with premium mechanical performance.
Steel frame and steel face fire doors with calcium silicate core. Common in industrial facilities, warehouses, hospitals, and infrastructure projects. Our boards maintain dimensional stability for precision welded steel door construction.
Wood-veneered, laminate-faced, and composite fire doors widely used in architectural projects. Our boards bond well with adhesives, accept wood veneer surfaces, and provide the fire core that enables decorative doors to achieve fire ratings.
Production-friendly properties and batch-to-batch consistency for large-scale door manufacturing.
A1 non-combustible (EN 13501-1). Supports fire ratings from FD30 to FD120 with correct door construction and hardware.
Tight density tolerance batch-to-batch. Every door produced with our core material has predictable fire and acoustic performance.
CNC routable, drillable, and edge-bandable with standard woodworking tools. Minimal dust generation. Clean cut edges for quality finish.
Tight tolerance on thickness (±2mm) and flatness. Essential for accurate door leaf assembly and proper frame sealing.
We can pre-cut boards to your exact door blank dimensions, reducing your production waste and material handling time.
100% asbestos-free and formaldehyde-free. Safe for factory workers and end-users in residential/commercial buildings.
Our recommended grade for fire door core material — combines high density, excellent mechanical strength, and A1 non-combustible classification for reliable fire door performance.
Sufficient density for FD30/60/90/120 fire door applications. Excellent machinability for CNC routing, edge banding, and hardware cutouts. Consistent density ensures predictable fire test performance.
