Scenic Cast Iron CORQ

Designing the aging of rust. Landscape-compatible castings that harmonize with COR-TEN.

CORQ is a landscape cast iron that allows you to enjoy the rust color and the heavy texture unique to cast materials. Over time, it changes to a deep brown and harmonizes beautifully with natural stone, plantings, and COR-TEN. Due to its higher price range compared to typical outdoor flooring materials, it is more suitable as an accent in places that emphasize the taste and rarity of the material rather than for uniform coverage over large areas. It is recommended for symbolic finishes in special spaces such as gardens, entrance approaches, and courtyards of luxury residences and estates, as well as public facilities, museums, art galleries, temples, cultural facilities, and memorial squares. By combining five different surface designs, you can create a unique expression for each piece. Kumagai Special Steel sells samples individually so that you can check the texture and weight before adoption. Please feel free to inquire about this opportunity!

CORQ: Bringing the texture of rust to your feet. Introducing CORQ, decorative castings.
