LIGHT GAUGE FINISHES

Architectural Metal, Finished to Inspire.

Explore distinctive colors, textures, and finishes designed to bring depth, character, and lasting beauty to architectural metal.

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.

NATURAL METALS EVOLVE OVER TIME

Pre-weathered and pre-oxidized natural metals are available in deep black and brown tones, offering a darker aesthetic expression while retaining their authentic metallic character.



Over time, these initial finishes will evolve as the natural patina develops—a process that occurs more rapidly in coastal or high-humidity environments due to increased salt and moisture exposure.

Zinc

All zinc surfaces gradually transition to a soft, uniform gray.

Terne-Coated Stainless Steel 444

Develops a soft, matte gray patina with a pewter-like appearance as it weathers.

Copper, Brass & Bronze

Evolve toward rich browns and ultimately green patinas as they age.

Muntz Metal

Darkens significantly over time, achieving an almost black, deep brown tone that highlights its distinctive composition.

LIGHT GAUGE PVDF FINISHES

Pre-painted coil and sheet metals ready for fabrication. Available on aluminum, stainless steel 316L, and galvanized or Galvalume steel substrates.

For Light Gauge applications, the paint finish is applied to the coil or sheet before fabrication.
