Green-tech cast iron grilles add a long-lasting finishing touch at London's Queen Mary University campus.

Green-tech was asked to supply 14 heavy-duty Coverdale cast iron grilles to offer protection from both pedestrian and vehicular traffic. Made in the UK from 100% recycled material., should the need arise, they are also 100% recyclable.

To ensure a long life, our Coverdale grilles are manufactured using Engineering grade 250 cast iron, with an expected lifespan in excess of 100 years, even with minimal maintenance or repainting. This impressive durability is down to the fact that 250 Grade cast iron does not rust in the traditional sense. Even if left unpainted, over 100 years, Green-tech cast iron grilles will only lose a few microns to oxidisation.

The standard finish is one coat metal primer followed by a Weathershield rust resistant paint system available in most RAL or BS colours. The grilles are all made to order in a variety of styles and can be supplied with irrigation or uplighter holes.
