Architectural Bronze

Also called 385 or C385 brass, architectural bronze is a copper alloy in a similar vein as naval brass and Muntz metal. As it contains a high proportion of copper, architectural bronze is characterized by a somewhat reddish color (copper alloys are sometimes called “red metals”). Due to a combination of its appearance, relative durability, and affordability compared to other red metals, architectural bronze is, fittingly, highly favored in architectural projects.

At Polished Metals, we’re a proud supplier of high-quality metal finishing on a wide range of 385 architectural bronze products, including sheets and plates, bars, pipes, and more.

What Is Architectural Bronze?

Architectural bronze, also called 385 bronze or 385 brass, is an alloy composed primarily of copper, zinc, lead, and often trace amounts of iron or other metals. With a rich, dark grayish brown color, this metal provides a very unique appearance that is highly sought after. In addition, its composition and manufacture make it more affordable than many other red metals, making it a prime choice for high-volume projects.

Industries and Use Cases

As the name suggests, architectural bronze is highly favored in architectural projects, particularly in the form of exterior sheets and plates for buildings, entrances, facades, and more. This metal also sees plenty of use in smaller-scale projects where designers hope to add a more rustic appearance to the building they’re working on. 

In addition to plates and sheets, 385 bronze is also commonly seen in other shapes and forms, including bars, tubes, channels, and more. It may be used for door and window frames, ornamentation on gates, and other decorative elements. Finally, this elegant metal can also be seen in interior features as well, such as building lobbies and elevator interiors, doors, rails, and more. 

Is Architectural Bronze Brass?

Strictly speaking, while both bronze and brass are copper alloys, bronze traditionally contains tin while brass is alloyed with zinc. This means that, despite its name, architectural bronze is technically a form of brass. However, due to its appearance, which is somewhat dissimilar to traditional brass (or Muntz, also a form of brass) and more similar to bronze, this metal is generally referred to as architectural bronze.

“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. Product arrives undamaged and is of good quality 99% of the time and when there is an issue with damage or defects Polished Metals responds quickly and makes things right quickly. I highly suggest using Polished Metals for your quality metal needs.”

“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.”
