As high-density urban infrastructure, modern hospitality complexes, and commercial architectural marvels evolve, internal compartmentation safety has transitioned from a basic regulatory requirement to an intricate architectural discipline. Custom OEM aluminium internal fire doors represent the intersection of lightweight structural integrity, rigorous fire containment performance (EI30 to EI120 standards), acoustic attenuation, and ultra-sleek aesthetic customization.
Leveraging decades of specialized metallic engineering, our manufacturing infrastructure operates on strict international quality management standards. Unlike generic timber or basic hollow steel door fabricators, our engineering model focuses exclusively on multi-chamber extruded 6063-T5 aluminium alloy profiles integrated with high-density intumescent cores and polyamide PA66-GF25 thermal breaks.
Every profile frame is extruded using premium-grade 6063-T5 aluminium billet, engineered with reinforced wall thicknesses (1.8mm to 3.0mm) to withstand extreme thermal pressures and prevent structural warping during high-temperature fire exposure events.
Our OEM interior fire doors feature non-combustible silicate boards, high-density mineral wool, and perimeter graphite intumescent sealing strips that expand up to 25 times their original volume upon heat threshold activation (180°C), completely blocking toxic smoke, flame, and hot gases.
From 5-axis CNC hinge prep machining to automated corner crimping and structural air/water tightness checks, 100% of finished assemblies undergo strict dimension verification matching client architectural shop drawings prior to export packaging.
When specifying internal fire door solutions for commercial high-rises, luxury hotels, and institutional facilities, architects and procurement heads must evaluate lifecycle durability alongside initial cost and fire compliance.

The global fenestration procurement ecosystem is undergoing a seismic structural transition driven by global building decarbonization targets, modular off-site prefabrication, and evolving life safety mandates.
Enterprise procurement teams are mandating Environmental Product Declarations (EPD) and requiring low-carbon aluminium profiles extruded using hydro-powered energy. Recycled content in 6063-T5 profiles significantly lowers embodied carbon while satisfying LEED v4.1 and BREEAM sustainability metrics.
To counter escalating site labor costs, developers are moving away from multi-vendor assembly. Sourcing complete pre-hung OEM fire door packages—inclusive of pre-milled latch plates, embedded drop-down acoustic seals, and factory-glazed fire glass—drastically reduces site installation errors.
Modern B2B procurement relies heavily on manufacturers capable of generating parametric BIM objects (Revit, IFC formats). This allows architectural engineering firms to validate opening clearances, fire rating compliance, and hardware collisions virtually before mass OEM manufacturing commences.
Urban high-density developments require internal doors to solve both acoustic control and fire containment simultaneously. Modern specs demand doors delivering up to 42-45 dB acoustic isolation while maintaining full EI60 fire protection for hotel corridors, executive suites, and medical facilities.
Continuous innovation in material science and hardware engineering is redefining what is achievable with custom OEM aluminium internal fire doors.
Next-gen hybrid intumescent polymers expand at lower temperature thresholds (120°C) with higher physical expansion forces, creating zero-clearance smoke seals around concealed hinges and latch mechanisms without altering narrow visual frame sightlines.
Advancements in nano-gel laminated fire-resistant glazing enable ultra-clear vision panels with zero tinting or distortion, offering up to EI90 integrity while maintaining minimal, elegant aluminium clamping beads matched seamlessly to the main frame profile.
Integration of magnetic hold-open devices, concealed motorized door operators, and real-time sensor feedback into central Building Management Systems (BMS) ensures automatic fire door closure during emergency triggers while facilitating touchless daily operation.
Comprehensive answers designed to aid architects, structural engineers, and international sourcing professionals in verifying technical compliance.
Our custom OEM aluminium internal fire doors are engineered and tested in accordance with EN 1634-1, BS 476-22, and UL standard frameworks. Depending on profile multi-chamber design and internal silicate core configuration, we deliver solutions rated for EI30 (30 minutes insulation & integrity), EI60 (60 minutes), EI90 (90 minutes), and specialized EI120 configurations for high-risk compartmentation areas.
While uninsulated aluminium melts around 660°C, our fire-rated doors utilize structural thermal breaks combined with high-capacity internal composite ceramic inserts, fire-resistant mineral cores, and intumescent graphite wraps. During a fire event, the intumescent strips swell instantly to shield the structural extrusion from heat transfer, preserving structural integrity while preventing flame penetration for the certified duration.
We provide full OEM surface customization including QUALICOAT-certified architectural powder coatings (RAL spectrum), anodized metallic finishes (champagne, bronze, black, silver), and 3D heat-transfer wood grain sublimation. This allows the aluminium door to replicate luxury natural timber aesthetics while maintaining 100% termite, moisture, and fire proofing performance.
To provide accurate engineering proposals and unit pricing, please submit your project window/door schedule or architectural drawings including: structural opening dimensions (width x height x wall thickness), required fire rating (e.g., EI30 or EI60), acoustic requirements (dB rating), glass specification (e.g., clear fire glass vs. solid panel), hardware hardware preferences (concealed closer, panic bar, electric strike), and target destination standards.
All finished assemblies undergo rigorous export packaging protocols: frames and door leaves are wrapped with anti-scratch protective film, corners are secured with heavy-duty plastic guards, and units are sealed in shock-absorbing EPE foam before being loaded into fully enclosed, ISPM-15 certified heat-treated fumigated wooden crates or steel-reinforced export frames for crane/forklift site handling.
Yes. Our 5-axis CNC machining centers pre-mill all mortise cutouts, concealed drop-seal channels, wiring conduit paths, and hinge prep according to your specified hardware template (e.g., Dormakaba, ASSA ABLOY, GEZE, or custom hardware kits). Pre-testing hardware fitment at the factory eliminates expensive site modification costs.
