  Other details as Sigma 200          
   
       
    Complete package auxilaries like sleeves, supports, couplng rods etc.  
  Fast and reliable supply from our  own factory  
  Optimal profile shape, about 20% (strong side) to 75% (weak side) stronger than comparable profiles from local suppliers  
  Because of the high steel grade, on average 20% bigger span possible compared to similar purlins  
  Extra secondary stiffener, so no cutting edges for workers and quicker and safer assembly  
  Eaves beams with distinct angle at no extra charge  
  Standard profile dimensions, supports and auxilaries are always the same, independent on spans, truss distances etc.  
    Easy standardized details   
  Available for roof, wall and floors  
  Purlins can be packaged per wall, roof and axis with no extra charge

  Roof purlins:          
 
   
   
   
 
       
  Roof purlins are produced at our own factory by measure and with holes for assembly  
  3-span purlins provides the greatest strength  
Use sleeves to shorter purlins or assemble 2-span purlins staggered
Keep a space of approx. 15 mm between the truss and the purlin  
  Eaves beams are supplied with an angled top flange, so only 1 profile is needed where roof and wall meet instead of 2. See fig. A
