Tree Grille

Tree Grate

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.

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.

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.

Variants

One version is available in steel to withstand heavy loads. Another version has a concrete sub-frame to control root growth and an optional irrigation tank.

Character

Tree grilles are extensions of the pavement that protect the roots while allowing rain to funnel through to water the tree.
