Weathering steel, most famously known as COR-TEN steel and sometimes written directly as "Corten steel", is a group of alloy steel which can form a stable rust-like appearance if exposed to the weather for several years.

AHL CORTEN’s new series of garden light can not only create exquisite shadow art, but also provide a central focus ornament in any landscape both day and night.

The combination of rusty looking corten steel with sculptures makes a unique metal art that well matched the natural environment, it also improves the sense of hierarchy for landscape.
