Glass-reinforced plastic (GRP), is a composite material, fibre-reinforced polymer made of a plastic reinforced by fine fibres made of glass. GRP has a high strength to weight ratio, high temperature range, high mechanical properties and is fire retardant. Additionally, GRP is also chemically inert and isn’t susceptible to creep.
STAKKAbox™ ULTIMA Hybrid is suitable for installation in environments rated to Class D load rating (ultimate limit state design of 240kN) under the Australian Standard AS/NZ 3996.
The ULTIMA Hybrid utilises the ULTIMA Connect system with the added feature of ULTIMA beams specifically developed for large scale access pits of 2 metres in length and above. Manufactured to a variety of sizes, the ULTIMA beams provide enhanced lateral s
