Achieve maximum structural efficiency with our high-strength galvanised purlin sleeves. Manufactured to nest perfectly over our Z–purling profiles, these joiners are the essential component for creating a continuous, multi-span roofing system that offers superior load-bearing capacity and rigidity
Continuous Span Performance: Our sleeves allow Z-purlins to be joined over rafters, creating a continuous run. This system is significantly stiffer and stronger than traditional butted joints, making it the industry standard for large-scale buildings.
Precision Nesting Fit: Specifically engineered to fit the exact geometry of our 140mm, 175mm, and 200mm Z-purlins, ensuring a snug, flush connection that eliminates structural play.
Matching Gauge Options: Available in both 6mm and 2mm high-tensile galvanised steel to match the thickness of your purlins, ensuring uniform strength across every joint.
Galvanised Protection: Fabricated from prime galvanised British steel to prevent rust and maintain structural integrity at the most critical points of your roof frame.
Rapid On-Site Assembly: Designed for a straightforward bolted connection, our sleeves help contractors maintain high installation speeds while ensuring the roof remains perfectly level.
What is Anti-Con? | Dripstop™ Anti-Condensation Technology
Anti-Con is an effective solution to combat the effects of water condensation on the underside of your roof cladding which if left unchecked can damage machinery, spoil livestock bedding and ruin stored goods.
We apply the Anti-Con Dripstop™ lining during the manufacturing process, rolling it along with the steel through our profiling mill, applying it to the reverse of the roof sheet. We leave the overlaps free of Anti-Con, so water doesn’t get drawn into the laps.
It’s recommended to use Anti-Con wherever condensation should be kept under control, or in areas of high humidity such as:
Chill Rooms
Food Storage
Workshops
Equestrian & Agricultural Buildings
Garden Sheds & Summer Houses
Garages
Grain Stores
How it works
As a condensation control membrane fleece, Anti-Con Dripstop™ absorbs the condensation and prevents it from dripping down. For it to work effectively, we recommend the ridge and eaves be left open without the use of foam fillers for ventilation, allowing the membrane to dry between cycles.
We recommend a minimum roof pitch of 10° when using Anti-Con, so if you have a roof pitch below this, please get in touch with our team on 01278 557 002 or email info@colourcladprofiles.com.
When used in livestock buildings, the humidity generated is much higher than normal which is why we recommend the use of Anti-Con in these situations. The table below shows area requirement per animal to keep the humidity levels under 80gm/m²/ hour.
