Z Purlins are light gauge steel sections/rails/mezzanine floor components for agricultural, industrial and commercial projects. Purlins are integral to the stability of the structure connecting rafters/beams from 800mm to 10M bays.
Davies Bros Panels and Profiles steel purlins are made from dipped galvanised steel; coated to G275 239 with a minimum yield of 390N/M2
Z Purlins (roof) or side rails (walls) can be connected using a sleeved or butted system
Sleeved. This system is used on a building with 3 or more bays. The sleeve sits on the cleat and connects two Z Purlins on one plate.
This adds to the strength and rigidity of the structure.
Butted This system is used when the structure has small spans or light loadings. It is also used when the application does not allow the use of a sleeve, eg within the web of the rafter.
Davies Bros Panels and Profiles steel sections have all been tested and designed to meet the BS & European Standards. Davies Bros have a full range of standard sections for all of your new build projects. We also have the ability to match existing designs for refurbishments or extensions.
