Thick-walled Tree Grilles CorTen Square are available in a wide range of patterns - square or round. The diameter of the aperture always measures a third of the grille’s overall width, e.g. ø33 and ø60 cm - 13” and 24” in 100 and 180 cm - 39” and 71” wide grilles respectively. We recommend CorTen steel frames when installing tree grilles at ground-level in order to provide adequate support and to maintain uniformity with street paving.
Possibilities and restraints
Available in square sizes of ca. 100, 120, 150, 180 or 300 cm
