FRP Tree Grate & Tree Guard Grating
FRP tree grate panels protect tree roots and soil while letting water and air through. Lightweight, corrosion-proof fiberglass guards for sidewalks, plazas and urban landscaping.
FRP (fiberglass reinforced plastic) tree grates sit flush around the base of street and plaza trees, covering the soil without sealing it. The open mesh allows rainwater, air and nutrients to reach the root zone while supporting pedestrian traffic and preventing soil compaction.
Compared with cast iron or steel tree guards, fiberglass tree grates are a fraction of the weight, will not rust or corrode, are non-conductive and stay comfortable underfoot in direct sun. They are easy for crews to lift for maintenance and can be cut on site to fit the trunk opening.
We supply molded tree grate panels in standard mesh sizes with optional resin grades, colors and edge details, fabricated to the dimensions your landscape design requires.
