gt Dentdale Tree Grille

The gt Dales Collection Tree Grilles are manufactured entirely in the UK from 100% recycled materials. Our Tree Protection is made from engineering grade 250 Cast Iron they are expected to last up to 100 years in normal use - even with minimal or no maintenance and painting. This is because 250 grade cast iron is not only incredibly durable, it also does not rust in the traditional sense - in fact over a 100 year timescale, even if left unpainted, Green-tech tree grilles will lose only a few microns to oxidisation. Green-tech can offer a standard range of tree protection as well as bespoke and one off products if required. gt Tree Grilles can be supplied with both irrigation and/or uplighter holes. We recommend that all grilles are fitted using a support frame and security clamps.
