The patented, precision-engineered truss-to-truss connection ensures each roof truss comes together with pinpoint accuracy. Once connected, the trusses remain locked in position and cannot shift or rotate. By eliminating this movement you also eliminate significant movement in your ceiling plasterboard which often leads to wavy roof lines and cracks. In addition to perfectly flat ceilings, Supaloc Steel trusses are engineered for silence. The unique factory fitted bracket connections feature ensure minimal movement and no annoying creaks or groans.
