Builders Beam is a unique rectangle hollow steel section, designed to replace the heavier steel  and timber sections used in building and construction industries. 

​

Made to the Australian Standard AS1163 it is Grade C350 and can be produced in either pre-galvanised (Z120) or black finish.

​

It is light weight and cost - effective, which allows for greater spans between support stumps and beams, in roofing and flooring.
