PolyGrate (Structural Plastics Corp)
PolyGrate™ tree grates are designed to protect trees and keep pedestrians safe in streetscape environments. PolyGrate™ is made of 100% post-consumer HDPE recycled plastic and is recyclable, non-toxic and will never leach harmful contaminants into surrounding soils. They are lightweight, extremely durable, easy to install, expand and maintain, and are a third of the cost of comparable iron tree grates. 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. PolyGrate™ tree grates have ultraviolet inhibitor additives to ensure they will last for years and won’t fade or become brittle even in the harshest conditions of salt, humidity, cold and heat.
