Galvanised Steel Z Purlins Sections
Cardinal Steels offers a comprehensive selection of steel purlins, including Z purlins and C sections, designed for a wide range of building applications. Our Z purlins serve as essential horizontal beams in constructing the roof and wall joists of building shells. They are strategically positioned between the roofing sheets and the building structure, ensuring the sheets are securely supported and firmly attached.
Our Z purlins are manufactured in-house at our Bromsgrove facility. This allows us to maintain stringent quality control, offer competitive pricing, and ensure rapid turnaround times. Steel Z purlins are highly versatile and lightweight, making them particularly suitable for agricultural and industrial buildings of various sizes.
We offer steel Z purlins in a variety of thicknesses and depths, tailored to meet specific load-bearing requirements. The choice of thickness and depth is determined by the span the purlin covers and the required weight capacity. We also manufacture and supply high-quality galvanised Z purlins designed to complement our steel roofing sheets. Our purlins are easy to install and are suitable for use with both insulated and uninsulated roofs and wall spaces.

What Are Z Purlins?
Z Purlins are structural members that are used as a framing element in metal structures, typically in the form of a ‘Z’ shape. They are designed to join the roof and wall joists of the building structure.
-
How Far Can Z Purlins Span?
Z Purlins can span a variety of lengths depending on the load they are carrying. As standard Cardinal Steels offers up to 6.100 m lengths and in 177 mm and 200 mm, ideal for use with our corrugated panels or box profile sheets.
-
What Is The Difference Between C Purlin And Z Purlin?
C purlins take their name from their shape, and are generally used to support roofing, cladding or insulation material. Z purlins are ‘Z’ shaped and are typically used for structural bracing to support both roof and wall elements. Z purlins have an angle less than 90 degrees making them flexible to be used across a variety of purposes.
-
Why Are Z Purlins Used?
Z Purlins are used in many lightweight metal structures such as warehouses, garages, and agricultural buildings as they provide strong, rigid, and supportive framework for the structure.
-
How Thick Should Purlins Be?
Purlins should always be chosen with the correct thickness according to the load requirements of the structure. Typically, purlins of between 1.2 and 3.0mm thickness are appropriate for most structures. Cardinal Steels offer eaves beams as standard 190 mm deep with a 2.0 mm thickness.
-
What Is The Difference Between A Girt And A Purlin?
Girts are horizontal structural members that are used to support wall panels, while purlins are vertical members used to support roof panels.
-
What Materials Are Used To Make Purlins?
Purlins are typically made of galvanised steel, but other materials like aluminium, stainless steel, and reinforced steel can also be used. Cardinal Steels’ manufacture in-house at their facility in Bromsgrove. This ensures our they are of the highest quality, optimum price, and with a fast turnaround.
