Nola Tree Grille Tree Grate
TREE GRILLE TREE GRATE
TREE GRILLE TREE GRATE
Design By Anders Nyquist
This iron tree grate is installed at the same level as the pavement surrounding the tree.
The tree grate allows the soil underneath it to remain uncompacted, encouraging healthy roots. The grate allows the tree roots to absorb water, air and sunlight while protecting them from pedestrians and traffic. Able to withstand weights up to 12 tonnes, the tree grate is strong enough to resist the pressure created by growing tree roots that can break many similar products.

CHARACTER
Tree grilles are extensions of the pavement that protect the roots while allowing rain to funnel through to water the tree.
MAINTENANCE
Over time, cast iron may develop rust on the surface but it will not affect the structural integrity. Anti-rust treatments may be applied from time to time.

ASSEMBLY AND PLACEMENT
The surface grille’s own weight is substantial enough to secure it to the sub-frame without fittings. If it is installed without the sub-frame we recommend securing it with metal fittings Ö30-72, which you will need to include in your order.

- Length : 140 cm
- Width : 140 cm
- Depth : 60 cm
MATERIALS AND SURFACE TREATMENTS
Cast iron. The tree grille is made from cast iron with a thickness of 50/44 cm. The sub-frame is made from zinc electro-plated steel with U-beam USP80. The root control barrier is made from reinforced concrete with a thickness of 10 cm (there are openings in the bottom to enable roots to grow deeper).
