What is a significant benefit of using Cor-Ten Steel in sculptures?

Using Cor-Ten Steel in sculptures is particularly valued for its visual appeal, which is enhanced through the process of natural rusting. This steel alloy is designed to form a stable rust-like appearance after exposure to weather, which not only protects the underlying material from further corrosion but also creates a distinct, earthy aesthetic. The patina that develops can vary in color and texture over time, adding character and uniqueness to each piece. As such, artists often select Cor-Ten Steel to bring a dynamic quality to their work that changes with the environment, making it both an artistic and functional choice. This characteristic of evolving appearance is what distinguishes Cor-Ten Steel in the realm of sculptural materials.
