Horizontal Tree Grilles

The Arborsystem tree grilles are manufactured to an extremely high standard under rigorous quality controls.  The majority of our tree grilles are manufactured from cast ductile iron. However, we also offer a range of fabricated grilles which can be produced in mild or stainless steel. Our range of tree grilles can be made to suit any application. If they are going to be subject to exceptional loading, heavy duty frames will be required for the cast ductile grilles and the fabricated steel grilles will be manufactured from larger section material.

The standard finish is matt black polyester powder coated. This high quality finish is extremely durable. Any colour from the RAL range is available as an option. For extra protection on mild steel products zinc galvanising is standard, followed by a high quality coating to any RAL colour.


This range can be manufactured in almost any size to suit your designs.
