Weathering steel is often recognized by its distinctive, rust-colored appearance—but there’s much more to this material than its looks. At Central Steel Service, one of the questions we hear often is: “Is the weather resistance a coating? What happens if the plate is cut or welded?” The answer is simple: No. Weathering steel is not coated. Its corrosion resistance comes from the chemistry of the steel itself.

Weathering steel is well-known for the rusty, orange-brown “patina” that it develops overtime. While this aesthetically-appealing patina serves as a protective, corrosion-resistant barrier, it can produce rust run-off as it develops. The Weathering Process Just like standard steel, weathering steel is silver in its original state. When...

While there are several benefits of using weathering steel, the fundamental benefit is its ability to resist corrosion. The atmospheric corrosion resistance of weathering steel enables it to be used unpainted in many structural and architectural applications for structures, including bridges, open-frame buildings, transmission towers,...

When specifying weathering steel for bridges, buildings, or architectural applications, engineers often encounter two commonly used terms: COR-TEN® and ASTM weathering steel. While they’re frequently used interchangeably, there are important distinctions that can impact your project’s specifications, sourcing, and long-term performance. Understanding the difference ensures you select the right material and avoid unnecessary limitations in procurement.

At Central Steel Service, we’re proud to supply the weathering steel material that helps bring bold architectural visions to life. On this unique residential project, designed by ARQ Architects and fabricated by Sheet Metal Supply, the decision to use weathering steel was central to achieving the homeowner’s goals. We were pleased to supply the raw weathering steel material that was later formed into wall panels, roofing, and snow guards  culminating in a striking home with enduring beauty and performance

When it comes to design and construction, blending materials can create visual interest, structural versatility, and long-term durability. Weathering steel, known for its rust-like patina and exceptional strength, pairs beautifully with a variety of other materials in both architectural and industrial projects. Whether you’re working on a bridge, building façade, landscape feature, or interior installation, mixing weathering steel with wood, glass, stone, or concrete can produce striking results.

Weathering steel, often recognized by its popular trademark COR-TEN®, has evolved from a utilitarian industrial material into a sought-after design element across architecture, landscaping, and infrastructure. As we progress into 2025, architects, landscape designers, and civil engineers continue to find innovative ways to incorporate this rugged yet refined material into the built environment. Below, we explore the key design trends shaping the use of weathering steel today.

As spring approaches, homeowners, landscape architects, and gardening enthusiasts alike are planning ways to refresh outdoor spaces. Weathering steel continues to gain popularity for landscaping and garden applications due to its durability, low maintenance, and natural aesthetic appeal. It is a functional and beautiful addition to any garden or landscape project for several reasons…

When most people hear the word "corrosion," they think of rust as a destructive force that weakens metal structures. However, in the case of weathering steel, corrosion can actually be beneficial. Instead of corroding, weathering steel develops a protective patina over time, shielding it from further deterioration and extending its lifespan.
