An aluminum panel exterior wall is an exterior cladding system where aluminum panels are installed on a supporting frame or substrate to form the building’s outer skin. It’s typically non-structural (non-load-bearing)—the building’s structure carries the loads—while the aluminum panels provide weather protection, a finished architectural appearance, and optional insulation/acoustic performance.

Design a welcoming façade with a aluminium panel facade—clean lines, solid structure, and tailored glazing for bright, open entrances.
Customize height, width, and module layout to match your opening and façade grid—available in fixed, operable, or sliding configurations.
Customize perforation patterns, hole sizes, and open-area ratios to control daylight, ventilation, and visual privacy—while matching your façade geometry.
Specify profile sections, finishes, and colors to meet structural requirements and deliver the exact look your project demands.
Installing a Aluminum Panel Exterior Wall requires precision for seamless design and optimal structural performance.
Verify substrates, slab edges, and datum lines; mark façade grid, levels, and bracket locations to control alignment.
Fix anchors/chemical bolts and adjustable brackets to the structure; check spacing, torque, and pull-out requirements.
Install vertical mullions/rails and secondary members; plumb and level to form a stable plane for panel mounting.
Place insulation boards, air/vapor barrier (if specified), and fire barriers at floor lines; seal gaps per project details.
Confirm panel ID, dimensions, finish, edges, and cut-outs/perforations; keep protective film on and avoid surface damage.
Hang panels using the specified fixing method (hook-on/clip/screw/rivet); maintain consistent joint width and panel flatness.
Install gaskets/sealant, flashings, and drip edges; ensure drainage paths and ventilation cavities remain unobstructed.
Check alignment, fasteners, joint uniformity, and water-tight detailing; remove film, clean surfaces, and complete handover records.
A Aluminum panel exterior wall offers a sleek and modern appearance for various applications, enhancing both the aesthetics and functionality of the structure.
Aluminum panel systems are opaque cladding (often with insulation behind), while glass curtain walls are transparent glazing systems focused on daylight and views.
Yes. Perforation patterns, hole sizes, and open-area ratios can be customized for shading, ventilation, privacy, and façade texture—while still meeting structural needs.
Typical aluminum panel thickness is chosen based on wind load, panel size, and flatness requirements. Larger panels and higher wind zones usually require thicker panels or reinforcement.
Common options include PVDF/FEVE coating, powder coating, anodized-look, brushed, and metallic finishes, with custom color matching (e.g., RAL/Pantone) available.
Most aluminum panel façades work as a rainscreen: water is managed by joints, flashings, gaskets/sealants, and drainage paths rather than fully “sealed” panels.
Lead time varies by finish, perforation complexity, and quantity. Shop drawings approval and sample confirmation usually impact the schedule the most
Elevation drawings, panel layout/module size, project location (wind zone), finish/color, perforation requirements, insulation/fire targets, and preferred installation method.
