Purlins

Staalbeer manufactures a unique 30mm top hat section that can be used for Purlins and or Brandering on Light Steel Trusses or any Timber Truss System. Purlins are manufactured from 0.58mm or 0.50mm 550MPA Galvanised steel.

Why use Staalbeer Purlins on your roof construction:
• The web features a textured finish to aid with the location of roofing screws.
• Purlins have a folded lip to prevent cutting of your hands with sharp edges during installation.
• Purlins have a guiding line in the lip for easy location of a TEK screw
• Purlins are supplied cut to the correct length to avoid wastage on site.

Purlins must be secured to the top chord of each truss using two fasteners at each point. Either of the following fasteners can be used:
• TEK SCREW #10x16MM HEX CLASS 2 – typically used in low cost applications
• #14X22MM STITCHING SCREW – A superior fastener

For Concrete Tiled roofs purlins should be spaced at 320mm c@c. At the eave a Staalbeer a Tilting spacer should be installed to lift the bottom row of the purlins by 20mm in order to ensure a level tile.

For steel roofs the following purlin spacing should not be exceeded:
IBR 0.50 mm – 1.50m
Widespan 0.50mm – 1.20m
Corrugated 0.50mm – 0.90m

If a customer requires a purlin gable overhang of >300mm it is recommended that purlins are braced using a second purlin that is fitted on the underside of the overhang and protrudes through the gable wall to support the existing purlin.

If it is necessary to join purlins it should be joined on a truss with a minimum overlap of 150mm

Brandering

Staalbeer produces a unique 15mm top hat section that can be used for brandering.

Brandering is manufactured from 0.50mm 550MPA Galvanised material.

Typicaly brandering is spaced @450mm centres.

Brandering must be fixed to the bottom chord of the truss using the following fasteners:

  • TEK SCREW #10x16MM HEX CLASS 2 – typically used in low cost applications
  • #14X22MM STITCHING SCREW – A superior fastener

If it is necessary to join brandering it should be joined on a truss with a minimum overlap of 150mm
