Due to the well-engineered, compact and weight-optimised design of the HYDROTEC tree grates, a simple, fast and therefore cost-efficient assembly is ensured.

By focussing on functionality and a few common standard dimensions and designs, we are able to provide a tree protection solution that offers an excellent price-performance ratio.
