Zinc Gutta manufactures their guttering systems in 0.7mm zinc as this is one of the most adaptable and cost-effective guttering materials on the market, plus it ensures easy installation and a 100% recyclable product. The Zinc Gutta 90-degree external corner lengths are designed to sit within close proximity of the corners of your home. These allow the rainwater to be effectively diverted around difficult angles with complete ease, protecting the integrity and appearance of any building. Similarly to the rest of your guttering, we recommend that fascia brackets are placed in intermediate 150mm centres for maximum strength throughout the system. Please note: One joint must be ordered for each length of gutter, gutter section and corner.
