Heavy Gauge Panel Systems

CSI Heavy Gauge Panel Systems are fabricated from solid plate materials to achieve exceptional flatness, rigidity, and long-term durability. Unlike light-gauge cladding, heavy plate construction creates a more monolithic architectural appearance while maintaining superior resistance to wind loads, oil-canning, and deformation.



These systems are well suited for high-performance façades, soffits, column covers, feature walls, and other architectural elements where precision, strength, and refined detailing are critical.


Available material thicknesses include:

  • Aluminum: 1/8” – 1/2”
  • Copper: 24 oz, 36 oz, 48 oz
  • Stainless Steel: 1/8” – 1/4”
  • Cor-Ten Steel: 1/8” – 1/4”
  • Brass, Muntz, Zinc: 1.2 mm – 1.5 mm


CSI systems can be engineered with routed returns, welded corners, concealed fastening, and custom sub-framing to meet the aesthetic and performance requirements of contemporary architectural design.

These robust systems exhibit minimal to no oil-canning, depending on panel size and metal thickness.

CSI-WAP Series

CSI-WAP Series

Our flagship product, the CSI-WAP Series incorporates integrated backside stiffeners, further enhancing flatness and dimensional stability - ensuring clean, crisp lines and long-term visual integrity. Available with Hexagon Micro PVDF, a post-fab applied baked enamel where ultra-fine metallic particles interact with light in a way that creates remarkable depth, vibrancy, and movement across the surface.
