Corten Steel Helix Moongate Arch

The Corten Steel Helix Moongate Arch is a spectacular sculptural feature designed to bring height, depth and architectural interest to an outdoor space. Inspired by the traditional circular moongates found in Chinese garden design, its dramatic twisting form creates a contemporary passageway that naturally draws the eye through the landscape. The sweeping helix shape appears to rise from and disappear back into the ground, making it an impressive focal point for pathways, entrances and large garden borders.

Manufactured in the UK from genuine Corten weathering steel, the arch gradually develops a rich, protective patina in shades of warm orange and deep brown. This naturally evolving finish complements planting, stone, timber and gravel while helping the structure withstand year-round outdoor conditions with very little maintenance. The generous hollow-box construction gives the arch a bold, substantial appearance suited to both contemporary and traditional garden designs.

Measuring approximately 2.5m high, 3m wide and 3.8m long, the Helix Moongate provides a spacious walkway while creating an immersive tunnel-like effect. Its extended form can also be used to frame a view, connect different areas of a garden or support climbing plants for an increasingly natural appearance. Beautiful from every angle, this is more than a garden arch, it is a lasting piece of outdoor sculpture that changes character as its distinctive Corten patina matures.
