3 Reasons to Use Corten Steel Garden Edging for Your Next Project

Complements diverse garden styles, from modern to rustic:

• Whether your garden is sleek and contemporary or features a more traditional, rustic vibe, corten steel edging fits right in. Its versatility allows it to harmonise with various designs.

About “The Conversation Garden” Featuring Corten Steel Garden Edging: 

Awarded Gold at the Melbourne International Flower and Garden Show, the intention of the garden was to create opportunities to open dialogue between family and friends.

The Conversation garden includes circular areas for people to gather face-to-face and reconnect away from devices and distractions, such as a rounded fire pit, curved dining space, and circular spa.

​This garden was designed according to a client’s brief. Lightweight concrete planters and a modular system for assembling the corten steel garden edging and hardscapes enabled the team to transport the structural components and soft furnishings directly to the clients’ backyards.
