Marshalls Street Furniture 65P Series Tree Grille is traditional in design and is constructed from polyurethane, which is an ideal material for tree grilles. A Ferrocast Tree Grille is not only resistant to corrosion but also the degradation that can be caused by street cleaning equipment. Grilles are also abrasion resistant and, because of their through colour, always present an optimal appearance. Ferrocast Tree Grilles are much lighter than cast iron and will reduce the risk of manual handling injuries (Manual Handling Operations 1992). Discounts of up to 15% are available for bulk orders on certain products. Call, live chat or email us for details.
