Are mesh panels suitable for curved aluminum facade applications?

Curved aluminum mesh façades offer fluid architectural expressions but require careful consideration of panel flexibility, fabrication, and installation techniques. Aluminum alloys in the 3000 and 5000 series with thicknesses below 1.2 mm inherently possess sufficient ductility for gentle curves (minimum radius of 1.5 m). For tighter radii, select ultra-thin gauges (0.8–1.0 mm) or opt for perforation patterns that increase panel flexibility, such as elongated slots parallel to the bend axis. Panels can be roll-formed on specialized CNC roll benders to achieve consistent curvature without crease marks. To maintain uniform panel alignment on a curved grid, utilize adjustable mounting brackets or slotted holes in carrier profiles, allowing minor on-site adjustments. Ensure joint detailing accommodates differential thermal expansion; use rubber gaskets or neoprene washers at fastener locations. When multiple panels form a continuous curve, butt-joint the perforated edges and conceal seams behind aluminum ribs or shadow profiles for a seamless appearance. Pre-assembly mock-ups are recommended to verify fit and finish. With the right alloy, gauge, and fabrication method, aluminum mesh panels can adapt elegantly to curved façade geometries while preserving structural integrity.
