Like any other building material, weathering steel has advantages and disadvantages. Depending on the project, application and location, weathering steel may or may not be the right material choice.

Advantages

These weathering steel edge sealing plates are a good example of weathering.
Weathering steel provides many benefits for the structure including:

Corrosion resistance

The most obvious and important benefit of weathering steel is corrosion resistance. Patina provides a layer of protection for the elements and extends the life cycle of the steel. Ultimately, this helps save costs.

Don't need to paint

Weathering steel reduces or eliminates the need for exterior paint, which makes maintenance of the structure easy and cost effective.
It can also help you avoid some of the problems associated with volatile organic compounds (VOCs) in some paints.

Ideal for heavy duty construction

Weathering steel provides strength and durability suitable for heavy duty construction. Weathering steel suppliers provide detailed information on the strength and durability of their weathering steel products.

Attractive appearance

Weathering steel has a rust protection that creates an attractive reddish-brown appearance, especially for industrial looks.
The weathering process produces different shades of red and orange to create depth, interest and texture.
Weathering steel creates a multidimensional facade that enhances the building's appearance. Few other materials can achieve the depth and variety of color and texture that weathering steel can provide.

Minimal maintenance

Generally speaking, steel has the lowest maintenance costs, and weathering steel is no exception. But corten does offer some unique benefits in the sector. Corten can withstand high temperatures without causing corrosion.
