Z Purlins
Z Purlins are perfectly suited to building projects of all shapes and sizes but are extremely effective in larger building projects. With over 25 years of manufacturing high quality roofing materials, we pride ourselves on delivering high quality at a low cost with minimal delays. At Mighty Structural, we aim to provide all of our loyal customers with a complete roofing system at a modest price. To help achieve this, Z Purlins can be a vital asset to keep up with customer demands and provide adequate protection.
What are Z purlins?
Z Purlins are galvanised steel beams, which can be safely and conveniently attached to the roof and wall cladding sheets of any building, representing tremendous versatility and adaptability. Z Purlins help to provide a strong and sturdy complete structural solution, which is ready for the heavy demands of roofing and side cladding. Supporting roof sheets or vertical wall cladding, Z Purlins represent tremendous value for money and versatility for an extensive range of purposes.
The ‘Z-shape’ of the purlins helps to overlap joints and represents greater strength and sturdiness than ‘C-Purlins’. Z Purlins save up to 40% of the steel used and are 25% of the cost, resulting in significant time and space savings to increase efficiency.
Strong and lightweight, our Z Purlins can span upwards of 25 feet depending on the roof load and the spacing of the Z Purlins. Additionally, Z Purlins can be nested together as a splice in roof construction, so the final roof support system appears to be one unbroken purlin, providing efficiency and durability. Offering robustness and flexibility, Z Purlins are a traditional yet effective system of sheet support that are easier to install and handle than traditional timber.
