Suitable for Septic Tanks and Water Tanks
The Nobis lightweight access cover and frame can be cast into any concrete tank lid or screwed/ bolted to any plastic, steel or fibreglass tank. 600mm and 450mm diameter clear opening covers are available, each able to withstand a load of 1.5 tonnes or a force of 15kN. They are suitable for light traffic areas.
The covers and frames are made of a composite material of fibreglass and special resin that is moulded at high temperature and high pressure. The manufacturing process changes the molecular structure of the material to produce a very high strength light weight product.
