Graepel’s tree protection grates protect the root zones of urban and street trees while allowing for safe, flush integration into paved outdoor areas. They prevent soil compaction, are permeable to water and air, protect against drying out, and ensure a durable, load-bearing surface that is safe to walk on in public spaces.
As a system supplier of perforated and formed sheet metal, Graepel develops and manufactures tree protection grates for long-term use in urban infrastructure.

Technical Design and Engineering
Graepel manufactures steel tree protection grates with appropriate surface treatments. Typical versions are available in hot-dip galvanized or Corten steel for long-term outdoor use.
The structure typically consists of several segments that are mounted around the tree trunk. This allows for easy installation as well as later replacement or adjustment to the trunk diameter.
The structural design is tailored to the requirements of public spaces. Load-bearing capacity, material thickness, and surface finish are defined according to the intended use.
With its in-house metal forming and surface treatment capabilities, Graepel offers a seamless process chain—from development through manufacturing to finishing.
