What is Corten Steel?
Corten Steel is an alloy steel that has been designed to be weather resistant and corrosion resistant. It is highly resistant to rust and corrosion, making it ideal for outdoor use in a variety of applications. Corten Steel products are perfect for outdoor use as they can withstand harsh weather conditions, such as rain, snow, and extreme temperatures. They are also ideal for creating fire pits, pellet heaters, BBQ grills, and other outdoor products. Corten Steel products are durable, long-lasting, and require minimal maintenance.
Corten steel, also known as weathering steel, is a type of steel alloy that develops a unique patina as it ages. This patina creates an appearance of natural rust, which can be beneficial in landscaping and other outdoor applications.
Note: In the initial stage of application,corten steel shows a yellowish appearance.This is followed by a gradual change in the color of the protective rust from brown to a stable dark brown after one to two years in general application environments. Afterwards,the coloration shows no clear change except perhaps to a deeper dark brown.
