Sleeper Information: Outback Sleepers can be built from 200mm high to 4m high. Sleeper thickness will depend on the height of the wall and the engineering requests, and the steel that would be required is 125×65 Channel and 120UB65 I beam for walls up to 1m, unless stated otherwise by an engineer. Anything over 1m must have council approval and this will then require engineering. We have engineering for our sleepers that is available to your engineer if requested, they are AS3600/2009 compliant and certified. Outback Sleepers have recently updated their sleeper to be in accordance with the revised Australian Standard AS3600- Concrete structures (2009).
