History of Bronze in Architecture

The qualities of bronze have been known to man since the beginning of the Bronze Age over 4,000 years ago. The Romans were the first to use bronze in cladding doors. However, it took until the Middle Ages before bronze became more widely used for architectural purposes.

There are bronze doors still in existence dating back to the 15th century, demonstrating the durability of this material, although the majority of buildings which feature architectural bronze windows, doors and other decorative features date from the 18th and 19th century.

Investing in bronze guarantees that your products will withstand the test of time, providing years of enjoyment for yourself and for future generations.

What is Architectural Bronze?

Architectural Bronze is a manganese bronze, a copper and zinc based alloy containing small amounts of manganese, iron and aluminium, and is commonly used in architectural applications. The combination of these metals give manganese bronze its distinctive properties, including corrosion resistance, anti-seizing properties, durability and high strength.

The alloy is chosen for its aesthetic appeal, as it develops a rich, warm patina over time, which can enhance the overall appearance of a structure. The patina also acts as a protective layer, preventing further corrosion and enhancing the material's durability.

In addition to its visual qualities, architectural bronze also possesses excellent mechanical properties, longevity and ability to withstand harsh environmental conditions, making it suitable for structural applications.

Why Choose Bronze over Steel or Aluminium?

Architectural bronze is a timeless and truly special alloy of undisputed prestige, providing an exciting alternative to steel and aluminium windows and doors, and there are many very good reasons why one might choose to invest in architectural bronze.

Firstly, architectural bronze is a living material, subject to natural oxidation and therefore acquires unique and original shades over time. It does not require galvanising, powder coating or painting which can give any product a limited lifespan due to chipping or general deterioration.

Many of our clients will choose architectural bronze for its distinct warm, rich colour that gives windows a classic and elegant aesthetic appeal and ability to enhance the overall architectural design of a building. Architectural bronze is a naturally beautiful metal and should not be confused with other products which may have a bronze coloured powder coat finish.

Architectural bronze is a highly durable material that can withstand harsh environmental conditions, including exposure to moisture, UV rays, and extreme temperatures. It has a natural resistance to corrosion and is less prone to degradation compared to steel or aluminium, making it suitable for long-lasting window frames. It is also a sturdy material that offers excellent structural integrity.

The natural anti-corrosive properties work by developing a protective patina over time, which not only adds to its visual appeal but also helps prevent further corrosion. This characteristic makes architectural bronze windows a relatively low-maintenance option requiring only periodic waxing, compared to steel or aluminium, which may require more significant upkeep over the years.

Working on this project were Richard Griffiths Architects who are well known for their focus on conserving historical buildings. They were one of the first architects to recognise the value of our products and we are proud to have worked with them on many beautiful projects since.
