The most common finish for Unistrut channel is Pre-Galvanized Steel. Pre-Galvanized steel is great for most indoor applications, but is not so great for outdoor environments or environments with a lot of moisture or corrosive elements. For applications that need to be able to weather the elements, there is no material that offers more corrosion resistance than stainless steel Unistrut. This versatile and rust-resistant material has proven to be a game-changer in various applications, offering unparalleled resilience in even the most unforgiving settings.

Understanding the Enemy: Rust

Rust, or corrosion, is the natural enemy of traditional carbon steel. Galvanized and powder coated finishes offer a little more protection, but rust still poses a significant threat to structural integrity, in various environments, with any of these finishes. When carbon or zinc coated steel comes into contact with oxygen and moisture, your Unistrut project can start to get rusty. 

Rust not only tarnishes the appearance of your metal framing, but also weakens its strength and overall integrity. Coatings offer a rust resistant finish that can provide some longevity, but most contractors will go for stainless steel Unistrut for outdoor applications. It is the most durable and has the longest service life of any finish or material Unistrut is manufactured from.

Stainless Steel Unistrut: The Rust-Resistant Warrior

The introduction of stainless steel Unistrut has been a game-changer in the industry. Composed of an alloy containing chromium, which forms a protective oxide layer on its surface, stainless steel boasts remarkable resistance to rust and corrosion. The chromium content, often combined with other elements like nickel and molybdenum, creates a passive film that acts as an armor against the corrosive forces of nature.

Unistrut is manufactured out of both Type 304 (SS) and Type 316 (ST) stainless steels. SS material is more readily available and slightly less expensive than ST.

This unique attribute makes stainless steel Unistrut the ideal choice for projects exposed to challenging environmental conditions, such as:

Marine and Coastal Installations

The salty air and high humidity levels in coastal areas can quickly degrade traditional materials. Stainless steel Unistrut shines in this domain, as its corrosion-resistant properties help structures withstand the relentless assault of sea breeze and saltwater splashes.

Industrial Facilities

Factories and processing plants often expose materials to harsh chemicals, extreme temperatures, and abrasive materials. Stainless steel Unistrut provides an excellent solution, ensuring prolonged stability and integrity in such demanding settings.

Outdoor Infrastructure

Bridges, highways, and railroads face the constant challenge of harsh weather conditions, including rain, snow, and temperature fluctuations. Stainless steel Unistrut's rust-resistant nature bolsters the structural integrity of these vital infrastructures, minimizing maintenance costs and ensuring long-term reliability.

Food and Beverage Industry

Stainless steel Unistrut finds extensive use in food processing and storage facilities, where hygiene is paramount. Its corrosion-resistant surface ensures there is no risk of contamination due to rust, making it a safe choice for these sensitive applications.

When it comes to selecting materials for projects in hostile environments, stainless steel Unistrut emerges as a clear winner. Its rust-resistant properties, combined with excellent strength and versatility, make it an invaluable asset in the construction and industrial sectors. 

Whether you're planning a coastal installation, a chemical plant, or a durable outdoor infrastructure, stainless steel Unistrut provides the ultimate peace of mind, ensuring your structures stand strong and steadfast against the tests of time and nature.
