Weathering Steel Wire Mesh

Weathering Steel A242, also known as Corten steel, is a high-strength, low-alloy steel that is renowned for its exceptional resistance to atmospheric corrosion. This material is particularly well-suited for use in wire mesh applications due to its ability to form a stable rust-like appearance after exposure to weather. The patina that develops on the surface of A242 steel acts as a protective layer, preventing further corrosion and extending the material’s lifespan. This makes it an ideal choice for outdoor applications where durability and minimal maintenance are crucial. The steel’s composition includes elements such as copper, chromium, and nickel, which contribute to its enhanced weather resistance compared to conventional carbon steels.

In wire mesh applications, Weathering Steel wire mesh offers both aesthetic and functional benefits. The unique rusted appearance of the steel can add a distinctive, industrial look to architectural projects, while its structural integrity ensures long-lasting performance. This type of wire mesh is commonly used in a variety of settings, including fencing, facades, and landscaping. However, it is important to consider the environmental conditions where the mesh will be used, as the protective patina may not form effectively in very humid or subtropical climates, potentially leading to ongoing corrosion. Despite this limitation, A242 wire mesh remains a popular choice for many outdoor applications due to its combination of strength, durability, and low maintenance requirements.

Compared to plain steel, weathering steel contains a chemical composition that increases its resistance to atmospheric corrosion. Made to rust under the influence of weather, weathering steel develops a patina that acts as a protective layer to prevent corrosion of the steel. This material is suited for many applications in its unpainted condition. With time and consistent exposure to the elements, the weathering steel will go from a yellow-orange, to a deep rust orange color, to a dark brown.

Considerations when specifying Weathering Steel wire mesh:
Weathering steel is most commonly used in outdoor applications. It is important to note that since the protective patina that forms on weathering steel is rust, water runoff may stain adjacent materials such as stone or concrete. While the patina protects from corrosion, weathering steel does have its limits. In humid and subtropical climates it is possible that the rust patina may not stabilize and the steel could continue to corrode.
