With its bright aesthetic appearance, endless applications and environmental credentials, stainless steel is a popular choice for high-quality architectural finishes.

First defined in 1911, ‘stainless steel’ is the generic name for a range of corrosion and oxidation resistant iron alloys. Various grades are now used for every imaginable application- including extensively in building and construction.

An estimated 92% of the stainless steel used in architecture, building and construction is recaptured and recycled at the end of service according to the International Stainless Steel Forum, so it’s the natural choice for architects working towards BREEAM and LEED.

Common grades in architecture

Often listed in architectural specifications as simply, ‘stainless steel’ it is important to understand the differences between the various types and specify the correct grade of stainless steel for the application and environment.

The grades most frequently used in construction are 430, 304 and 316, also referred to as grades 1.4016, 1.4301 and 1.4401 according to BS EN 10088. Type 304 includes nickel which improves its resistance to corrosion, whilst Type 316 includes molybdenum to further improve its resistance, making it suitable for external or extreme environments.
