Flame Retardant Low Smoke Decorative Aluminum Sheet

Core Advantages

1. Halogen-free flame retardant coating, low smoke & low toxicity

   Special inorganic flame retardant additives inside PE coating. Effectively inhibit flame propagation. Low smoke emission without highly toxic halogen gas during combustion, greatly improving safety evacuation time for public areas.

2. Stable fire safety performance

   Pass standardized fire testing; low smoke density meets international public construction requirements. No molten dripping that causes secondary ignition risk.

3. Flexible coating for diversified processing

   Modified ductile paint system, no cracking or peeling during bending, stamping and edge hemming, suitable for various customized decorative panel forming.

4. Moisture & corrosion resistant

   Dense continuous coating prevents humidity and air oxidation, applicable for underground, humid public transit environments.

5. Clean matte surface, easy cleaning

   Anti-fouling smooth finish, dust and stains can be wiped off simply; multiple standard RAL colors available for unified interior decoration style.

6. Customized flat sheet specifications

   Thickness range 0.4mm–2.5mm; standard width 600–2650mm, arbitrary fixed-length cutting according to project drawing requirements.

7. Full-surface anti-scratch protective film

   Transparent PE film protects coating surface during transportation, cutting and on-site installation.

8. Eco-friendly low VOC coating

   Compliant with indoor environmental standards, no harmful volatile substances for long-term occupied public buildings.

Production Process

Aluminum flat blank feeding → Multi-cycle degreasing cleaning → Chromium-free environmental passivation → Constant temperature hot air drying → Halogen-free flame retardant PE primer coating & curing → Low-smoke flame retardant topcoat coating & secondary baking → Cooling → Anti-scratch film lamination → Fixed-length cross cutting → Fire performance sampling test → Coating thickness & color difference inspection → Full appearance screening → Dustproof export packaging

Each batch undergoes fire and smoke density sampling inspection before delivery.

Standard Technical Parameters

Main Application Fields

1. Public transit facilities: Subway station, railway station, airport interior ceiling and wall cladding

2. Medical buildings: Hospital ward, corridor, outpatient hall interior decoration

3. Commercial complex: Shopping mall ceiling, public passage decorative panels

4. Education buildings: School classroom, gym, auditorium interior wall panels

Export Packaging Standard

Each flame retardant aluminum sheet is separated by soft anti-scratch separating paper. The whole stack is wrapped with multi-layer moisture-proof PE film and thick kraft paper to prevent dampness and surface abrasion during ocean transportation. Sheet stacks are firmly fixed on IPPC fumigated wooden pallets by steel strapping to avoid collision deformation. Clear shipping marks mark alloy grade, thickness, size, coating type, color code, net weight, gross weight and batch number. We can supply fumigation certificate, MTC, fire & smoke test reports and complete customs clearance documents for overseas engineering tender and import inspection.

Inspection & After-sales Service

Seven strict pre-shipment inspection processes: coating thickness test, color difference comparison, cross-cut adhesion test, fire & smoke performance sampling test, salt spray test, flatness inspection and full surface defect screening. We provide complete technical documents for project bidding. Our technical team offers free processing and installation guidance. If coating peeling, inconsistent surface or performance defects are confirmed within 7 working days after receipt of goods, we will reply within 24 hours and provide targeted solutions.

FAQ

Q1: What is the difference compared with ordinary prepainted aluminum sheet?

A: Ordinary PE aluminum sheet has no flame retardant function and generates heavy toxic smoke when burning. This product adopts halogen-free flame retardant coating, low smoke & low toxicity, specially designed for public construction with strict fire safety codes.

Q2: Can it be used for subway and hospital interior projects?

A: Yes. Low-smoke and non-toxic combustion characteristics fully meet fire specifications of public transport and medical buildings, widely adopted in global public decoration projects.

Q3: Can you provide official fire and smoke density test reports?

A: We can supply third-party test reports of flame retardancy and smoke density, supporting overseas engineering bidding.

Q4: Will fire-resistant performance decline after bending processing?

A: The flame retardant ingredient is evenly distributed inside the paint film. Normal bending and forming will not damage flame retardant and low-smoke properties.
