Galvanised steel tree guard

COR-TEN® steelsteel

Product overview
By executing Tree Guards in Corten steel too, a comprehensive, harmonious whole is created with the Tree Grilles Corten. The Tree Guards provide protection around tree trunks while offering a refined, architectural appearance. The Round Tree Guard features an understated, minimalistic design that follows the shape of the trunk and serves as an alternative to classic tree guards. All Tree Guards use the Guardlock® mounting system for a clean, detailed connection between guard and grille.

• Round Tree Guard: minimalistic, follows trunk shape; detailed finish.
• Lotus Tree Guard: vertical, concentric Corten slats for a natural appearance.
