The Australian Standard (AS/NZ 3996) specifies requirements for access covers and grates for use in vehicular and pedestrian areas. It applies to access covers and grates having clear openings up to 1300 mm, particularly to components manufactured from grey and ductile irons, cast and manufactured steels, aluminium and concrete.
Cubis Systems’ standard precast concrete pits and access covers can be manufactured up to a Class G load rating (extra heavy duty use with a serviceability design load of 900 kN) which can be used for docks and aircraft pavements subject to very high wheel loads. We have also gone further to match the load rating of the pit to its cover, which is why our pits offer the most superior solutions on the market. This design element provides long term confidence in the quality and endurance of the product.
