The HUMBERG grating protects the delicate root system of the tree with a multi-part, galvanized profile steel construction that is easy to assemble and allows for uncomplicated maintenance. On request, the gratings are also availabel in stainless steel or with a non-slip surface and with different mesh.
The complete system is 99% recyclable due to the material used.
Gratings set modern accents with their clear and harmonious structure. Both the LINEAR and the GRID designS impress with their puristic appearance and can be adapted to any root ball size.
HUMBERG gratings are laid on a supporting structure made of galvanized tubular steel. This is taken up by the outer frame of the HUNO® TreeCare concrete foundation with integrated root space supply for optimal gas exchange and the best possible supply of the root system.
