The system may be used with all types of claddingsand roof pitches, within the limitations given in this number of spans is 2 and the maximum span DETAILS ON PAGE 45 LOAD TABLES ON PAGE 33 SLEEVED DOUBLE-SPAN SYSTEMS leeves are provided at all penultimate supports and arestaggered at internal bays. The advantage is a reduced numberof erection components when compared with the SleevedSystem. Note that maximum section length is restricted to 15mfor transport and handling reasons.

6 Consideration should begiven to handling and erection sequence when utilising thedouble-span sections. Minimum number of spans is 4 andthe maximum span is DETAILS ON PAGE 45 LOAD TABLES ON PAGE 33 HEAVY END-BAY SINGLE-SPAN SYSTEMThis is a highly efficient sleeved-system, with sleeves at allsupports thus allowing a form of continuous beam bay sections and sleeves are thinner than at the end baythus allowing an economic solution for long buildings. Sleevesat penultimate supports are of the same thickness as the outerbay purlin section. Minimum number of spans is 4 andmaximum span is DETAILS ON PAGE 45 LOAD TABLES ON PAGE 37 HEAVY END-BAY DOUBLE-SPAN SYSTEMS leeves are provided at all penultimate supports and arestaggered at internal bays.

7 The advantage is a reduced numberof erection components. Inner bay sections and sleeves arethinner than at the end bay thus allowing an economic solutionfor long buildings. Sleeves at penultimate supports are of thesame thickness as the outer bay purlin section. Minimumnumber of spans is 4 and maximum span is DETAILS ON PAGE 45 LOAD TABLES ON PAGE 37 Four structural systems are available, the Sleeved System, Double-Span Sleeved System, Heavy End-BaySystem and the Butted System. These systems allow for a flexible and efficient range of solutions to roofingsupports for a wide variety of cladding types, the major features of which are outlined Purlin SystemsVisit us at our website Depot Tel 028 406 31242 Fax 028 406 38753 BUTTED SINGLE-SPAN SYSTEMThe system is required for buildings of a single span length andis efficient for short spans or light loadings.

8 Butted purlins arealso useful for frames which have large clear spans and wherelarge frame deflections may be harmful to continuous purlinsystems. Butted purlins can be used over supports or within thedepth of the supporting section.

Differentcladdings provide varying restraint to the purlin and it isextremely important that the roof designer should be clear onthe type of roof cladding prior to selecting a suitable sagsystem.

10 For purlin design purposes within the scope of thismanual the following list outlines the main cladding types to beconsidered:1) Restraining type metal ) Non-restraining type metal ) Hook bolt fixed ) Tiled restraint is usually provided to the purlin where normaltrapezoidal, or composite cladding is through-fixed to thepurlins and where the sheets are fixed together by side lapstitching. Standing seam roofs and some forms of secret fixpanels have fixings which allow relative movement between thepurlin and the cladding and these panels should be regarded asnon-restraining unless used in conjunction with a suitable linerpanel. A suitable liner panel should be sufficiently robust tocarry compressive restraint forces and should be positively fixedto the purlin and it is also recommended that side lap stitchingis adopted to form a roof plane diaphragm.
