Corten Steel Gates

Decorative, eye-catching metal gates are a good way to make a statement with your outdoor design. They provide both form and function, giving a sense of definition to the area both physically and aesthetically. One popular choice for fine, high-quality outdoor gates is corten steel, favored for its appearance and notable properties that make it well-suited for outdoor installation.

What is Corten Steel?

Also known as weathering steel or by its proper trademark name as COR-TEN steel, this material is a unique steel alloy often used in architectural projects, particularly where it would be exposed to the elements. Corten steel, which comprises two alloys of similar composition—A588 and A606-4—is rated for high atmospheric corrosion-resistance, but how this works is different from materials like stainless or galvanized steel. The alloy takes on a rust-like patina when exposed to weather conditions over a long period of time, but this doesn’t compromise its structure. In fact, this protects the steel from further corrosion.

Why Corten Steel?

Corten steel gates acquire a distinctive rustic look without requiring maintenance to keep them in one piece. Unlike normal rust, the patina does not flake away, so it protects the underlying steel. Corten steel also does not require painting to achieve this appearance, though you can clear-coat the surface after a solid patina forms if you wish. Most corten steel pieces will come unrusted so the patina can form on its own. The result is a stylish and sturdy steel gate with a naturally forming “re-purposed” aesthetic. Corten steel pieces can also safely be welded together, for those who want to make their own additions to an installation.

Instead of fearing weather conditions like rain, snow and moisture, corten steel gates are improved by them. In the right climate, corten steel offers a striking yet beautiful look perfect for outdoor spaces.
