CORRUGATED CORE ALUMINUM COMPOSITE PANEL
Precision roll-bonded continuous structural architectural sandwich panel featuring an engineered sinusoidal wave core made from 100% recyclable high-grade aluminum. Eliminates organic thermoplastic resins completely, delivering uncompromising EN 13501-1 Class A1 fire safety, exceptional rigidity-to-weight ratio, and flawless optical flatness. Series: ALU-CC-4000.
What is the ALU-CC-4000 Corrugated Core Panel?
Unlike FR-ACP with mineral-filled polyethylene, the ALU-CC-4000 eliminates organic thermoplastic resins completely. The patented 12.5mm wave-pitch sinusoidal aluminum core acts as an infinite series of structural I-beams — 100% recyclable, zero-VOC, and EPD ISO 14025 compliant for LEED v4 / BREEAM credits.
Panel Total Thickness
4.0mm standard envelope / 6.0mm high wind / 8.0mm megapanel.
Aluminum Skin Gauges
0.7/0.5mm standard architectural (3003-H14) / 1.0/0.8mm heavy impact (5005-H34).
Sinusoidal Core
12.5mm pitch roll-bonded wave flute, 2.8mm ± 0.05mm height — a continuous series of structural I-beams.
Fluorocarbon Finish
PVDF 3-coat, champagne metallic, and brushed FEVE exterior finishes.
Why Choose Our Corrugated Core Panels?
Tested under ISO/IEC 17025 accredited international laboratories — verified for extreme positive/negative wind loads, shear deflection, and zero-ignition structural performance.
Class A1 Zero-Ignition
100% aluminum mono-material — zero polyethylene, zero toxic gases, no smoke (s1), no droplets (d0) under EN 13501-1 / BS 476 Part 4.
Rigidity-to-Weight Champion
Flexural rigidity 0.245 × 10¹¹ N·mm²/m at just 4.32 kg/m² — 62% lighter than 3.0mm solid plate with equal stiffness.
±5.4 kPa Wind Deflection
ASTM E330 structural deflection pass at L/180 over 1500mm spans — no mid-stiffeners required on high-rise envelopes.
Circular Mono-Material
Zero delamination sorting at decommissioning; scraps melt directly into secondary ingot with <5% original smelting energy. >35% post-industrial content.
Mechanical Strength & Fire Physics Matrix
Coil-Coated Fluorocarbon Finishes
Continuous coil-coated PVDF and FEVE finishes with zero VOC emissions during the building lifecycle — compliant with Environmental Product Declarations (EPD ISO 14025).
Standard Milling Profiles & Cassette Assembly
Engineered for CNC V-groove routing using standard tungsten carbide 90° or 135° cutters. Panels fold seamlessly into rigid architectural cassettes without fracturing the outer roll-coated skin.
V-Groove 90° Routing & Flange Return (DETAIL 01)
Routed from the backside through rear skin and corrugated core; a calibrated 0.2–0.3mm core base remains undisturbed to prevent metal fatigue when cold-folding 90° returns. Minimum bend radius R = 2.0mm.
Concealed Fastening Cassette Z-Clip (DETAIL 02)
Cassette folded flanges riveted with structural corner brackets; panels hook onto continuous vertical aluminum T- or Z-runners with stainless isolating washers preventing bimetallic corrosion. 50mm cavity minimum.
Horizontal Shadow Gap Express Joint (DETAIL 03)
Engineered open shadow gaps (15–20mm) with dry-joint EPDM/Neoprene multi-fin continuous weather gaskets or open-joint rainscreen baffle designs with rear weeping drainage. Expansion allowance ±3.5mm per panel.
Subframe Integration & Movement Joints
Concealed cassette fixing with engineered movement joints for large-format corrugated core envelopes.
Concealed Fastening Cassette (Z-Clip)
Cassette folded flanges riveted with structural corner brackets hook onto continuous vertical aluminum T- or Z-runners with stainless steel isolating washers to prevent bimetallic corrosion. Sub-framing clearance 50mm cavity minimum.
Horizontal Shadow Gap Express Joint
Engineered open shadow gaps (15–20mm width) with dry-joint EPDM/Neoprene multi-fin continuous weather gaskets or open-joint rainscreen baffle designs with rear weeping drainage. Expansion allowance ±3.5mm per panel.
