All CORE Tree Rings apart from the weathered steel Cor-Ten effect have a 20 micron galvanised zinc coating.
The black and brown colours also have a further 110 micron UV resistant polyester powder coating, forming a durable scratch resistant barrier.
The Cor-Ten high grade weathering steel has a contemporary look with its naturally oxidised finish. After 5-6 weeks the stable rust-like look develops, forming a protective layer that prevents any further oxidation of the metal.
For softer ground, the CORE EDGE Pins and Clips Pack can be used to further secure the ring with 300mm rebar extension pins.
