CSI Architectural Metal LLC
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.
