- Product number
- Ö30-71 Tree Grille
Ö30-71BT80 Irrigation tank 80 l
Ö30-72 Fixtures (4 pieces)
Ö30-73 Sub-frame in steel
Ö30-75 Lifting device for tree grilles
- 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.
- Materials
- 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).
- 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.
- Character
- Tree grilles are extensions of the pavement that protect the roots while allowing rain to funnel through to water the tree.
