Benefits of Brett Martin Rectangular Plastic Downpipe.

Brett Martin’s Cascade range is the original cast iron alternative. The collection features an array of drainage solutions that mimic the authentic appearance of cast iron while harnessing the advantages of modern plastic materials. These qualities make it an excellent choice for period properties and heritage refurbishments, ensuring an authentic look with enhanced performance, cost savings, and improved safety.

When working on an industrial project that demands high-capacity drainage, such as structures with large roofs or buildings subject to severe weather conditions, you will likely require the Deepstyle 170mm guttering. Pair it with the compatible 100mm x 75mm rectangular downpipe for efficient and seamless installation.
