** NOTE TO SPECIFIER ** Neenah Foundry manufactures beautiful cast iron tree grates and guards in a variety of sizes and shapes. Protect your trees and add a touch of class and sophistication to your landscaping project many of our designs even allow for the inclusion of your city, neighborhood, or company logo. Whether for a downtown street, a quaint suburban neighborhood, or a new stadium or amusement park, Neenah Foundry is certain to manufacture a line of tree grates or guards that meet your exacting specifications.
Neenah is well known in the industry as a manufacturer of two-piece tree grates. We recommend using two-piece (180 degree section) tree grates for the best stability and longevity.
Why Cast Iron? Unlike steel, cast iron is inherently resistant to continued corrosion. When left unpainted, cast iron tree grates and frames will remain unchanged for decades. Cast iron tree grates from Neenah Foundry are strong and will stand up to urban abuse. (Note: not recommended for vehicular traffic) Cast iron tree grates are heavy enough to deter unauthorized removal without the need for lock down devices.

TREE GUARDS
 
** NOTE TO SPECIFIER ** Neenah Tree Guards are manufactured from hot rolled, pickled and oiled mild steel in the five standard illustrated styles. Guards are designed to be attached in four places to bolting lugs which are integrally cast to the underside of the tree grate.
Neenah Tree Guards are manufactured using .5" flat and .625" square steel stock. Our use of these heavier materials sets Neenah's Tree Guards apart from the others, making for a stronger and more durable product.
Neenah furnishes guards completely assembled in two half sections. Guards are supplied with the vertical bars bolted to the rings. No tree guards are available for octagonal openings.
