HSRM Spanlok® Roofing

A true performer in profiled roofs sheet with a touch of elegance and rigidity blended harmoniously. It remains one of the prefered and frequently specified roof types by architects and engineers in building projects. Product rigidity owning to interlocking ribs and a unique concealed clips fixing gives it a perpetual appeal.
The dense profile with its high rib forms has excellent spanning capability reaching purline over greater distance exceeding 1800mm, hence allowing for more economical designs. The deep trough between ribs allows it to be laid at extremely level pitch without the risk of a leak or water spilling over side laps.
Concealed clips fixing allows the profilesto be fixed easily by just pressing the sides onto clips until the roof catches on the bracket. It fits nicely with roof profiles and this ingenuity design has been tested to perform even under rigorous wind conditions generated in wind tunnels laboratories. Hence a safe load determined form the necessary conditions to sustain against roof pull outs due to wind uplift and suctions.
This roof profile is appropriate for buildong with large overall roof are such a warehouses, factories, office building or multipurpose halls.
