DHS or Dimond Hi-Span purlins are a galvanised steel modified cee section shape, offering a stronger shape with less deflection than the cee shape.
Available in sizes from 150mm high to 400 mm high, in material thickness up to 1.95mm thick to suit portal spacings up to 16m.
They require design calculations by a Structural Engineer.
Speed of installation is assured as DHS purlins and girts are supplied complete with punched bolt holes and brace channels ready for site assembly.
