The Zeta tree grille has a unique, completely invisible structure that allows interruption-free paving right up to the tree. Its low-profile design provides high strength and support for virtually any type of paving adopted for the surrounding street scene.
Zeta is even suitable for areas where access is required for certain types of vehicle.
The adjustable collar simplifies installation by absorbing variances in the tree pit build-up in any direction, and allows perfect finish levels and orientation.
Zeta comes supplied with a full tree pit irrigation / aeration system as standard. It has been used with excellent results in the most demanding, low tolerace locations.
Load-bearing capacity varies according to size of grille, paving type and build-up depth. FEA testing can be carried out for specfic projects. Virtually any load-bearing requirement can be achieved with engineering; light vehicular overrun is standard depending on paving type and build-up depth.
