Never rusts

Made of HDPE recycled plastic, PolyGrateTM never rusts, corrodes, or leaves unsightly streaks.


The lightweight PolyGrateTM can easily be a one-person installment without special equipment.


PolyGrateTM will not fade or become brittle even in the harsh conditions of salt, humidity, cold and heat.

A. D. A. Compliant

The radial design pattern of the PolyGrateTM meets the American Disability Act requirements.

Why PolyGrateTM is Different

Made from 100% post-consumer recycled plastic, PolyGrate™ tree grates are a great value and smart Green solution. They are lightweight, ship via UPS, are extremely durable, easy to install, expand and maintain, and are a third of the cost of comparable iron tree grates.

How PolyGrateTM Works

PolyGrate™ tree grates are designed to protect trees and keep pedestrians safe in streetscape environments.   The radial design pattern is functional and beautiful.   The radial openings are less than ½”W x 2 ¼”L, which make PolyGrate™ ADA compliant and easily expandable for larger trees and future tree growth.
