Z & C Purlins

Z & C Purlins are light gauge steel sections/rails/mezzanine floor components for agricultural, industrial and commercial projects. The Z & C Purlins are designed as secondary beam supports for roofing and cladding sheets, insulated panels and liner trays, for spans up to 10.0m. These purlins can be joined employing the overlap or sleeved system.

UPS supply Z & C Purlins in various thickness (from 1.50mm to 3mm) galvanised steel, designed for supporting either roof sheets or vertical wall cladding, they can also be used in conjunction with our built up system. Our state of the art supply equipment allows us to comfortably supply lengths up-to 12m. 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.

At UPS we 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.
