  8. Product description • Steel material • zinc-coated steel S350GD+Z275 • thicknesses: • 1.00, 1.20, 1.50, 2.00, 2.50, 3,00 • maximum and minimum profile height: 100 ÷ 400 mm • minimum profile length: 1000 mm • maximum profile length: 18 000 mm • Zinc coatings • Z275 g/m2 (20 μm)

  9. Light weight purlin LP-Z

  10. Light weight purlin LP-Z • LP-Z100 ÷ LP-Z350 • The Z section is excellently suited as a roof purlin • The major principal inertia axis is in pitched roofs with normal inclination in an approximately vertical position and thereby provides optimum load bearing capacity against the weight of structures and snow

  11. Light weight purlin LP-Z • The second moment of area about the minor axis, on the other hand, is so low that it is usually advisable to tie the sheet section on the slope of the roof to the opposite slope by a ridge moulding • The Z section is installed on the roof with the upper flange pointing toward the ridge • Z sections are applicable also as wall purlins, installed with the outer flange facing down

  12. Light weight purlin LP-C

  13. Light weight purlin LP-C • LP-C100 ÷ LP-C350 • C sections can be used as wall purlins or wall posts • The C section differs from the Z section by its centre of torsion, which in the C section is on the back side • Due to torsion, a vertical load acting on the section causes a transverse force component on the flange of the section, acting from the web up toward the upper flange

  14. Light weight purlin LP-C • If C sections are used as roof purlins, they need to be installed with the upper flange pointing toward the ridge • As wall purlins, on the other hand, they are installed with the flange facing up, whereby wind pressure loads partly counteract the self-weight of the wall structure • With wind suction loads, the transverse force components strengthen one another, and tie rods may be required to counteract their influence

  15. Light weight purlin – LP-S

  16. Light weight purlin LP-S • LP-S150 ÷ LP-S400 • A sigma section exhibits several plane areas separated by folds • This makes the manufacture of sigma sections more complex than the manufacture of Z and C sections, but this is compensated by the higher durability values owing to the better efficiency of the dimensionally smaller plane areas

  17. Light weight purlin LP-S • Thanks to this improved efficiency, the height of sigma profiles can be increased more than the height of Z and C sections • Sigma sections can be used on longer spans, or e.g. in sigma frameworks which are used in large span buildings to achieve moderate spans • A sigma framework is built joining two sigma sections back-to-back with 8-12mm distance pieces, with similar gauge sheet used as gusset pieces

  18. Light weight purlins – LP-H

  19. Light weight purlin LP-H • LP-H100 ÷ LP-H250 • The top hat section is wider than the sections referred to above • This gives it considerably higher lateral stiffness, which makes it suited to applications where the purlin is subjected to transverse loads, as well • Top hat purlins are attached directly from the flanges • They are used as roof purlins, wall purlins or, for example, as truss chords

  20. Light weight purlins Thermo • LP-Thermo Parameters: • Thickness: 1.0, 1.2, 1.5, 2.0 mm • Length: 6 – 8 m • Recommended spacing: 600 mm

  21. Light weight purlins Thermo • Thermal transmittance improvement (thermal bridges elimination up to 90%) • Acoustic parameters improvement -30ºC -30 -25 -3 +17 +19 +20ºC

  22. Application in buildings Back to the Contents page

  23. Application in buildings • Ruukki lightweight purlins can be used as a insulated and uninsulated roofs in following buildings: • production halls, • warehouses, • shopping centers, • offices buildings, • public buildings • sports buildings, • swimming pools,

  24. Technical parameters Back to the Contents page

  25. PurCalc • Ruukki’s PurCalc software is used to dimension the purlins

  26. Structural systems types: Single - span system Two - span system (multi - span system) Sleeve - extension system Overlap - extension system Structural systems

  27. Single-span system Used in walls and roofs, in moderate spans A simple system and the same support reactions of primary rafters in centre bays, small number of joint components Whole roof consists of similar purlins Higher consumption of steel Higher deflections Can be implemented with Z, C, top hat and sigma profiles 6mm 6mm 6mm L L L L Structural systems

  28. Two-span system (multi-span system) Used in walls in 4-6m spans, and in roofs in moderate spans Small deflections and small number of parts requiring installation Amount of installation work limited and different support reactions of principal rafters Long sections, more difficult to handle and can be implemented with Z, C, top hat and sigma sections L L L Structural systems

  29. Used in roof and wall structures System contains a special sleeve section, normally either similar gauge to basic purlin or max. 0.5 mm thicker. Optimal weight, small deflections, sections easy to handle A larger number of component, more installation work, for Z sections the sleeve section is identical to the basic purlin section and for sigma section, a C section is used as sleeve section Sleeve-extension system 6mm 6mm 6mm 0.13L 0.13L 0.13L 0.13L 0.13L 0.13L L L L L Structural systems

  30. Overlap-extension system Used in roof and wall purlins, in spans of 6-10m The purlins are overlapped inside one another, a double purlin or a thicker section in end bay Optimal weight and small deflections Long spans can be achieved, a larger number of joints, more installation work, can be implemented with Z sections 0.8L 0.13L 0.13L 0.13L 0.14L 0.13L 0.13L 0.20L L L L L Structural systems

  31. Certification Back to the Contents page

  32. Certification LP-Z, LP-C, LP-S, LP-H • Quality Certificates ISO 9001:2000 & ISO 14001:2004 • Technical Approval AT-15-5755/2008 • National Declaration of confirmity according to 58/A/2008 • Local Certificates when needed

  33. Benefits Back to the Contents page

  34. Benefits • Low weight of purlins • Material and shape is the key • High strength properties are very efficient • Wide selection of purlins to match requirements • Low transport cost and little space in transport • Longer spans than with alternative applicable solutions • Good corrosion resistance • Applicable also in difficult conditions • Fully recyclable material
