Resintuff Triangular Manhole Cover
The Resintuff 25 Ton Manhole cover provides a high-strength access solution for subsurface drainage and utility networks. This composite unit utilizes fiber-reinforced materials to achieve a C250 load rating. It fits standard 700mm x 700mm openings in residential and commercial environments.
Built for the Job
Civil contractors and plumbers specify this access unit for areas requiring medium-duty load bearing. The triangular configuration is a safety feature that prevents the lid from accidentally falling through the frame into the shaft during maintenance. Unlike traditional cast iron, the composite material offers no scrap value. This significantly reduces the risk of theft on public sites. The lightweight nature of the resin-based material allows for safer handling by site crews without specialized lifting machinery. It resists corrosive sewer gases and chemicals found in industrial runoff.
