DTS Dart - GreenBlue Urban

DTS Dart

The Dart tree grille is a premium round ductile iron tree surround.

Designing tree grilles is something GreenBlue Urban have been doing for over 2 decades. Beautiful timeless patterns have been created which add quality and flair to the urban environment. The fundamental critical purpose of tree grilles is to prevent soil compaction around the rootball. We have developed highly engineered design principles and finishing processes to ensure the durability of the structure and the coatings is robust enough to perform under harsh urban environments. The Dart tree grille is a premium square ductile iron tree surround.
