With long-lasting performance in mind, Kit Building Systems insists on only using top quality construction materials to build our structures. Our vehicle canopies are fabricated with a box section steel covering that is built onto a tough and durable galvanised steel frame. The steel framing is strong, light weight and rust resistant and the roof cladding has been engineered to withstand our tough British conditions. The 100% waterproof roofing has been built to last, with premium construction materials that are fully engineered. All our materials are, of course, fully compliant with British Standards.
