Tree Grates
Including E
xclusive Patented Paver-Grate

Tree grates have been used for many years to help integrate trees into the urban hardscape. Tree grates provide space for the tree while allowing pedestrian traffic over the tree planting area. They help to suppress weeds and trash accumulation in the tree planting area. Ironsmith offers a large array of sizes, shapes, and styles to choose from.
Paver-grates serve the function of a tree grate while allowing unit pavers to completely cover the tree planting area.

Safety Standards
All of our castings meet the standards for class 35B gray iron per ASTM A48. Tests of specific loads on specific grates can be performed if contractually required. The coefficient of friction of ironsmith cast iron grates is well within the safety standards established by the Ceramic Tile Institute, and ADA. Pedestrian proof grates are offered to meet every requirement.
Many of our designs allow the tree opening to be enlarged in increments to accommodate tree growth, protecting the tree from injury. Grates that are expandable will have the expansion sizes listed under "TREE OPENING" in their data base listing. Exceptionally large openings are available on some or can be custom ordered to accommodate large trees such as palms. If you have a particular opening requirement you can use our SEARCH feature to search for a grate by tree opening size.
