Exterior wall cladding panels are aluminum composite panels (ACP) manufactured for building facades, combining two pre-painted aluminum alloy skins bonded to a mineral-filled or polyethylene core in a continuous lamination line. The result is a rigid, flat panel that weighs 5.5-8.5 kg/m² yet delivers the surface quality, color consistency, and weather resistance that architectural facades demand over a 20-plus year service life.
The aluminum skins use 3003 or 5005 alloy at 0.3-0.5mm thickness, coil-coated with PVDF fluorocarbon paint that meets AAMA 2605 for color retention, chalk resistance, and gloss stability under prolonged UV exposure. For high-rise and public buildings where fire code mandates non-combustible cladding, mineral-filled FR cores at 70-90% mineral content achieve A2-s1,d0 classification per EN 13501-1.
Standard panel format is 4mm total thickness at 1,220 mm or 1,500 mm width and lengths up to 6,000mm. Panels are fabricated off-site by CNC routing, folding, and cassette forming before installation on the building’s sub-frame system. Applications span commercial facades, residential exterior cladding, retail shopfronts, transportation hubs, column covers, and signage.
Your Trusted Manufacturer for Exterior Wall Cladding Panel
RaxPanel operates a continuous coil-coating and lamination line in Hebei, China, dedicated to aluminum composite panel production. The coating line applies primer, PVDF topcoat, and protective film to aluminum coil in a single pass, with oven-cured paint film thickness monitored by inline gauges at 25-micron tolerance. Color is matched to the project RAL or Pantone reference under D65 daylight simulation before the coil enters the laminator.
The facility has produced facade panels for since 2002 at a daily throughput of 1,700 m², supplying architectural projects in more than 30 countries. Peel strength is tested per ASTM on samples from each coil changeover, and surface flatness is verified against a 1.5mm-per-meter straightedge before cutting. Finished panels are interleaved with protective film and packed in wooden crates sized for container loading. Send us your facade elevation drawings, color schedule, and core specification, and we will confirm panel format, coating system, and delivery timeline.

Exterior Wall Cladding Panel Selection Guide
Exterior wall cladding panels form the building’s weather envelope and its visible architectural face. The specification choices below affect weathertightness, thermal compliance, facade appearance, and long-term maintenance cost.
Pro Tip: Request the Full System From One Supplier
Ordering panels, flashings, sealants, and fasteners from separate vendors creates compatibility gaps and splits warranty responsibility. A single-source supply ensures the joint sealant, gasket profiles, and coating chemistry are tested together for 25-year weathertight performance.

1. Coating selection for facade durability
2. Joint design and rain-screen principles
Cladding panels manage rain through a pressure-equalised joint: the outer seal sheds bulk water while the inner cavity allows any moisture that bypasses the first line to drain back out. Tongue-and-groove joints with a ventilated cavity behind the panel face achieve this without exposed sealant beads, reducing maintenance and keeping the facade clean.
3. Thermal compliance and energy code targets
Panel thickness is the primary lever for meeting U-value requirements. A 100 mm PU panel achieves approximately 0.22 W/m²K, satisfying most European commercial energy codes. For projects targeting passive-house or near-zero-energy standards, 150-200 mm panels or a supplementary interior insulation layer bring U-values below 0.15 W/m²K.
4. Colour, profile, and architectural expression
Micro-ribbed, flat, and corrugated profiles create different shadow lines and visual textures on the facade. Standard RAL colours ship from stock; custom colours and metallic finishes are available with minimum order quantities. For multi-colour facades, order all panels in one production run to eliminate batch-to-batch shade variation.
Frequently Asked Questions
Can cladding panels be installed over an existing wall?
Yes. Panels fix to a secondary steel or aluminium sub-frame anchored to the existing structure. Verify the existing wall’s pull-out capacity before specifying the anchor type and spacing.
¿Cuál es el ancho máximo de panel para aplicaciones de fachada?
Los anchos útiles estándar son de 1.000 mm y 1.100 mm. Se ofrecen paneles más anchos, de hasta 1.200 mm, para fachadas de perfil plano donde la retícula de soporte permite una separación más estrecha entre cerchas.
¿Cómo se gestiona la expansión térmica en tramos largos de fachada?
Las sujeciones deslizantes en los soportes intermedios permiten un recorrido térmico de 2-3 mm por cada 10 m de longitud de panel. Los puntos fijos se colocan solo en un extremo, con juntas de dilatación en las zonas de movimiento del edificio.
¿Qué clasificación de resistencia al fuego se requiere para el revestimiento exterior?
Los requisitos varían según la jurisdicción y la altura del edificio. La mayoría de las normativas europeas exigen B-s1,d0 o superior para edificios de más de 18 m. Los paneles con núcleo de lana mineral alcanzan A2-s1,d0 para las aplicaciones más restrictivas.
