Overview

Tree Grille Galvanised Steel - Petal - Overview

This square galvanised steel tree grille uses a fanned, petal-style slot pattern radiating out from the central aperture to protect tree roots from pedestrian and vehicle traffic while still letting water and air reach the root zone. It is supplied as two bolted, interlocking sections for a secure fit around the tree base.

Frequently asked questions

How big is the aperture in the middle of the grille?

The central aperture measures 450mm across, sized to suit young to semi-mature street trees. Measure your tree's stem before ordering, since the aperture itself cannot be resized.

Does fitting the grille mean removing the tree first?

No. The grille is supplied in two galvanised steel sections that come together around the standing tree and bolt in place on site, so there's no need to lift it over the canopy.

Is there a difference between the galvanised and black powder-coated versions beyond colour?

Both share the same galvanised mild steel base for corrosion resistance. The black option adds a powder-coat finish on top, purely for a darker look that blends with certain paving schemes.

Can vehicles drive over this grille, or is it footpaths only?

The frame is reinforced to resist sagging under both foot traffic and light vehicle loading, so it suits car parks and access roads as well as pedestrian areas.

Do I need to buy a tree guard separately?

Yes, if you want to protect the trunk above ground as well. The grille only covers the root area at pit level; the matching Tree Guards - Galvanised Steel range pairs with it and is sold on its own.

Which of the three widths should I pick?

Match the width to the size of your tree pit. All three options - 900mm, 1000mm and 1200mm - use the same 450mm aperture and two-piece bolted build, so only the overall footprint changes.

Why does this pattern have wide fanned slots instead of a fine grid?

The petal-style cut uses longer radiating slots rather than a tight grid, giving a bolder look while still keeping the surface safe to walk on and open enough for rainwater and air to reach the roots.
