INTRODUCTION
Landscape Designers have found NEENAH's cast iron tree grates and
fabricated tree guards continue to be the strongest, most cost-effective solution for
protecting and complementing trees in urban environments.
With quality castings produced entirely in the U.S.A., you can
specify NEENAH with confidence, and choose from the largest selection of tree grates in
the industry.
WHY CAST IRON?
Unlike steel, cast iron is inherently resistant to continued
corrosion. Even when left unpainted, cast iron tree grates and frames will remain
unchanged for decades.
Cast iron tree grates from NEENAH are strong and will stand up to
urban abuse. Not recommended for vehicular traffic.
Cast iron is heavy enough to deter unauthorized removal without the
need for lock down devices.
