Use Cases for Architectural Sheet Metal

Finished sheet metal is commonly used across all architectural projects. A highly versatile product, sheet metal may be used for both exterior and interior features. For example:

  • Exterior cladding, including anti-vandalism cladding
  • Flashing and roofing
  • Storefronts and entryways
  • Marquees and other signage
  • Elevator parts, especially elevator interiors for wall and ceiling panels
  • Interior design, including wall and ceiling panels

Sheet metal is ideally suited to architectural projects for both the sleek, modern appearance it lends and for the practical benefits, including protection against damage and corrosion. 

Architectural Sheet Metal: Common Metal Types

Nearly all non-ferrous metals see use in architectural projects, but some are more frequently used than others. Some of the most common are aluminum, stainless steel, and copper, as well as Muntz metal or naval brass for buildings located near the coast.

Stainless Steel

Perhaps the most common architectural sheet metal, stainless steel sees frequent use industrywide. Available in multiple different compositions, stainless steel can be customized to meet the needs of almost any architectural project. Durable, strong, and long-lasting, stainless steel is a popular choice for architectural use cases.


Aluminum is a staple of the architectural industry. Highly resistant to corrosion, lightweight, and more affordable than many other metals, aluminum may be used in nearly any situation where architectural sheet metal is called for. Aluminum is commonly used in high volumes for building facades, walls and doors, metal siding and flashing, and sheet metal roofs. 


Copper is a metal that can truly stand the test of time—and come out the other side looking even better than before. Though pricier than other architectural sheet metals, finished copper offers both a unique look and desirable qualities that can’t be beat—including supreme resistance to corrosion and temperature changes. Architectural copper can most commonly be seen in roofing systems, flashings and copings, cladding, and various decorative design elements.

Muntz Metal and Naval Brass

Particularly for marine buildings and coastal projects, Muntz and naval brass may also be used as architectural sheet metal. These metals are specifically designed to withstand corrosion from seawater and other brine-like solutions with high salinity.

“I have worked with Polished Metals periodically throughout my 18 year carrier in the custom metal fabrication industry. They have been a consistent, reliable vendor for me both in regards to informational needs and as a product supplier. Quotes are often required to be turned around by me very quickly and Bob Gunther at Polished Metals sends me pricing and lead-times extremely fast. Our product arrives when we are told it will and if there are any delays (which does not happen often) we are informed ahead of time, which is appreciated.

“Polished Metals has been a Preferred Vendor of ours for over a decade. Our corporate philosophy dictates that we have Alternate or Secondary Supplier for all product, with the exception of #8 Mirror Polished Stainless Steel. We’ve tried to qualify other suppliers to no avail, as none of them can compete in any of the critical categories. The Customer Support provided by Bob Gunther cannot be replicated, pricing is fair, delivery is always on-time and quality is fantastic. As the Corporate Purchasing Manager for the last 7 years, not once have I had a negative experience with Polished Metals. I can’t say enough good things about them.”
