Truss & Ceiling Type
Roof trusses, manufactured from lightweight steel, are assembled and placed across the building at a maximum of 1200mm centres apart. These are secured to building using hurricane clips which are fixed to the truss and wall u channel using 25mm wingtex self drilling screws. Top hat purlins are fixed across the trusses at maximum 1200mm centres apart ensuring there are purlins both on the top and bottom edge. 0.58mm gemsbok roof sheeting ISQ300 (Z200) roofsheets are fixed on top. Rubber polyclosures or steel flute closures are used under roofsheets and ridge capping to ensure weather proofing.
A suspended ceiling system is used to conceal the ceiling void. A ceiling grid is fixed to the bottom chord of the roof truss using steel hangers and ceiling angles to the edge of the wall. 1200x600x9mm foil back gypsum ceiling tiles are then laid into the grid to complete the ceiling.
A Lattice beam, manufactured from lightweight steel, is fixed to the apex of the gable end and spanned the entire length of the building. Ceiling panels, manufactured similar to the wall panels, are spanned from the fascia end wall to the lattice beam, these are fixed with 65mm wingtex screws.0.58mm gemsbok roof sheeting ISQ300 (Z200) roofsheets are fixed on top of the ceiling panels. Rubber polyclosures or steel flute closures are used under roofsheets and ridge capping to ensure weather proofing.
