Manufactured in the brands highly recommended 0.7mm zinc, installers are tapping into a design that is built to last and can overcome even the worst weather conditions. Maintaining a continuous flow of water and drainage around the corners of your property will significantly improve the quality of your guttering system. That is why the Zinc Gutta 90-degree internal corner is a must-have item for anyone looking to install a drainage network that's built to stand the test of time. It's recommended that installers fit their corners alongside a fascia bracket, positioned around 150mm from the fitting to ensure there is no risk of sagging.
