Why CorTen Steel is the Best Material for Pacific Northwest Fireplaces
Low-maintenance. Weather-resistant. Built to last in Seattle and beyond.
If you’ve lived through a few Seattle winters, you know the Pacific Northwest isn’t easy on outdoor furniture — and fire features are no exception. Constant rain, damp air, and temperature swings can take a serious toll on traditional materials. Over time, paint peels, metal corrodes, and fire pits that looked great in summer become rusted eyesores by spring.
That’s where CorTen steel stands out.
Used in architectural landmarks, public sculptures, and high-end outdoor fireplaces, CorTen steel is designed to thrive in the elements. It doesn’t fight the weather — it works with it. That’s why we love it for our line of modern, wood-burning fire features here at Puget Sound Fire Pits.
What Is CorTen Steel?
CorTen (short for CORrosion resistance and TENsile strength) is a high-performance steel alloy developed to withstand outdoor weather conditions — no sealant or paint required.
Instead of rusting through like regular steel, CorTen forms a stable, protective outer layer of rust that actually prevents deeper corrosion. The more it’s exposed to the elements, the more durable it becomes.
Originally used in bridges, shipping containers, and large-scale architecture, CorTen has found a new home in sculptural outdoor fireplaces and modern landscape design. It’s beautiful, functional, and incredibly low maintenance — which makes it a perfect fit for the PNW.
Why It’s Perfect for Seattle & the Pacific Northwest
Seattle's rain is no joke — and when you’re buying a fire feature for your backyard, it needs to stand up to months of damp, wind, and mossy mornings. CorTen steel checks all the boxes.
Weather-resistant: Built for climates with rain, snow, and fluctuating temps
Rust-proof (in the good way): Surface rust acts as a shield, not a flaw
Won’t peel or flake: Unlike painted metal, CorTen never needs repainting
Long-lasting: Gets better with time, not worse
Great for coastal areas: Stands up to salty air and humid climates
In short, CorTen is built to survive — and look good doing it.
Low Maintenance, High Style
One of the best things about CorTen steel? You don’t have to baby it.
There’s no sealing, painting, sanding, or covering required. Just place it, light it, and let it do its thing. Over time, the metal naturally shifts into a rich, rusty bronze tone that blends perfectly into Pacific Northwest landscapes, whether you’re going for modern minimalism or earthy rustic charm.
Unlike traditional fire pits that corrode unevenly or need touch-ups every year, CorTen steel ages gracefully, developing a one-of-a-kind patina that tells the story of your space.
