ما مدى مقاومة الأسقف المصنوعة من شرائح الألومنيوم للحريق؟

Aluminum strip ceilings provide excellent fire resistance, as aluminum is non-combustible and does not contribute fuel to a fire. When tested according to ASTM E84 or EN 13501-1, powder-coated and anodized aluminum panels typically achieve Class A (USA) or Class A1 (EU) ratings, indicating the highest level of flame spread and smoke development performance. Carrier systems, hangers, and acoustic infill materials should also meet fire-safety standards. Mineral wool or fiberglass acoustic backing enhances fire resistance and thermal insulation. In case of fire, aluminum strips do not release toxic gases, supporting occupant safety. Architects often specify fire-rated versions of the ceiling system for corridors, stairwells, and high-occupancy areas to comply with local building codes. Overall, aluminum strip ceilings contribute to a building’s passive fire protection strategy while maintaining aesthetic and functional benefits.
