Stainless steel has always been a timeless material, but recently we have noticed a growing interest in it once again across both architectural and interior projects. Designers and architects are moving back towards cleaner finishes, durable materials, and more contemporary detailing, and stainless steel fits perfectly into that trend.

Not only is stainless steel visually striking, but it is also incredibly practical. One of its biggest advantages is exactly what its name suggests it is stainless. Unlike many other metals, stainless steel is highly resistant to rust, corrosion, staining, and general wear, making it a long-lasting and reliable material for a huge range of applications.

Understanding the grades: 304 vs 316

There are two main grades of stainless steel commonly used within architecture and design: 304 and 316.

304 stainless steel is the standard grade and is ideal for internal applications. It performs exceptionally well indoors and is widely used for interior metalwork, trims, fixtures, and decorative details.

316 stainless steel, often referred to as marine grade, is designed for external applications and harsher environments. It contains additional elements that provide increased resistance to corrosion, making it perfect for outdoor use or coastal locations where materials are exposed to moisture and salt in the air.

Although they are used for different environments, visually, the two grades look the same. Both can be finished in a variety of ways depending on the desired aesthetic, including polished, satin, and mirror finishes.

The finish that works in every setting

Another reason stainless steel is becoming increasingly popular again is its versatility. It can be used to create sleek minimalist spaces, but it also works beautifully when paired with warmer materials and finishes. Stainless steel can be combined with yellow metals such as brass and copper without causing a bimetallic reaction, allowing designers to mix materials freely and create more unique and luxurious designs.

Many people are surprised to learn that stainless steel can also be PVD coated to achieve a range of colours and finishes, and contrary to popular belief, it can also be powder coated. This gives architects and designers even more flexibility when incorporating stainless steel into modern spaces, whether they want a bold statement finish or something subtle and refined.

A sustainable choice for modern architecture

Another major advantage of stainless steel is its sustainability. Stainless steel is 100% recyclable and can be reused repeatedly without losing its quality or strength. In fact, a large percentage of new stainless steel is already made using recycled material.

Its durability also makes it a sustainable choice. Unlike other materials that may need replacing over time, stainless steel has an extremely long lifespan and requires very little maintenance. Its resistance to corrosion, staining, and wear means products and architectural features can last for decades, reducing waste and the need for replacement materials.

Why we’re seeing it return

As trends continue to shift towards durable, sustainable, and high-quality materials, stainless steel is proving that it is far more than just an industrial material. Its combination of strength, longevity, versatility, sustainability, and clean aesthetics is exactly why we are seeing it return so strongly within architecture and design today.
