Mezzanine Secondary Beams and accessories
Mezzanine Secondary Beams and accessories are lipped Cee section profiles, manufactured from pre-galvanised S450 grade steel, with a minimum yield strength of 450N/mm². The decking above the Cee sections helps spread the loads of the floor evenly and varies in thickness depending on the loads.
