HEAVY GAUGE FINISHES

Premium Finishes. Built for Bold Architecture.

Explore natural metals and high-performance architectural coatings designed to enhance the strength, depth, and distinctive character of heavy gauge metal systems.

NATURAL FINISHES

Available on Light Gauge Panels and select Heavy Gauge Systems (depending on finish), these options celebrate the living surface of natural metal as it matures with time - developing rich, organic patinas that reveal depth, authenticity, and craftsmanship.


Stainless steel is the exception, maintaining a timeless and consistent appearance that reflects its

enduring stability.

Heavy Gauge Premium PVDF Finish

Post-fabrication baked enamel finishes applied to CSI WAP, AHP, and FMP components. Each part is welded, ground, and blended until seams are invisible, then finished in a multi-stage enamel process that bonds directly to the metal surface.

Hexagon Micro Finish™ – Premium PVDF Metallic Coating

Inspired by the efficiency and beauty of hexagonal patterns found throughout nature, CSI Architectural Metal introduces Hexagon Micro Finish™ (CSI-HMF-PVDF) - a premium baked enamel PVDF metallic coating engineered to elevate architectural metal surfaces.


In nature, hexagonal geometry appears in structures where strength, efficiency, and visual harmony converge - from honeycombs to crystalline lattices. This same principle inspires the micro-metallic structure of CSI-HMF-PVDF, where ultra-fine metallic particles interact with light in a way that creates remarkable depth, vibrancy, and movement across the surface.


As natural light travels across the panel façade, the micro-metallic composition subtly refracts and reflects light, producing a dynamic interplay of highlights and shadows. The result is a surface that appears alive throughout the day - shifting gently with the sun’s angle, emphasizing architectural forms, folds, and panel geometries.

Whether applied to CSI-WAP™ welded aluminum plate systems, Reveal Roof Panel, façade cladding, soffits, or architectural accents, CSI-HMF-PVDF provides:

•Exceptional color depth and metallic brilliance

•Dynamic interaction with natural light and shadow

•Long-term UV stability and color retention

•Durable baked-enamel PVDF protection for exterior environments

•A refined surface finish worthy of contemporary architecture



The result is more than a coating - it is a light-responsive architectural surface, designed to enhance the sculptural qualities of metal façades and bring buildings to life.

CSI-HMF-PVDF Hexagon Micro Finish™

A premium metallic finish for contemporary architectural metal systems.

• Custom Baked Enamel PVDF System  color fuses to the substrate during curing, creating a luminous, durable surface that responds to light and shade.

• Select any tone from the RAL Color Chart, or provide a physical sample for custom color matching.

• Samples available in matte, satin, or polished finish levels.

• Custom metallic and special effect finishes available upon request.


Notes

• All PVDF finishes meet or exceed AAMA 2605 performance standards.

• Marine-grade systems available for coastal or high-humidity environments.
