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

Why PolyGrateTM is Different

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.
