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).

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.

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.

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.

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