Cor-Ten Steel Plate

Description

COR-TEN, known as weather-resistant steel, offers a robust solution to combat rust, which is a common challenge faced by conventional steel. When left exposed to the atmosphere without protective coatings, Corten steel naturally undergoes rust formation, much like ordinary steel. However, the alloying elements in COR-TEN facilitate the rapid development of a protective surface layer comprising finely-textured rust, effectively suppressing corrosion.

Advantage

1. Green and environmentally friendly There is no need for initial painting, which can reduce the use of fire-retardant coatings and fire-retardant coatings, thereby reducing pollution, shortening the construction period, reducing costs and reducing maintenance. It is an economical steel with "green environmental protection" and sustainable development;
2. High visual expression Weathering steel plates will change over time, and their color brightness and saturation are higher than those of ordinary structural materials, so they are easier to stand out against the background of garden plants;
3. Strong body shaping ability Weathering steel plates are relatively easy to shape into rich and varied shapes and can maintain excellent integrity;
4. Good spatial definition ability Thin weather-resistant steel plates are used to clearly and accurately separate the space, making the site concise and bright.
