Albion Z section purlins are manufactured by cold roll forming pre-hot dipped galvanised steel S450 having a guaranteed minimum yield strength of 450N/mm2 and a Z275 galvanised coating.

Albion Z section purlins and rail members are designed for use as secondary sheeting supports for spans up to 15m depending on loading criteria.

 

Albion can offer:

  • The largest depths of Z purlins available in the UK today.
  • Equal top and bottom flanges to reduce handing requirements, thus reducing mark numbers.
  • Flat webs providing simplified detailing solutions and a more friendly installation on site when used in conjunction with doors, windows and horizontal cladding.
