Corrugated Roofing Cyclone Assembly

The result of two years of design, development and testing, Corri-Lok® from Buildex® is the cyclone assembly for corrugated roofing profiles.


· The special patent protected feature of Corri-Lok® overcomes the problems associated with conventional cyclone plates.
· CORRI-LOK®’s unique design allows it to outperform current plates under cyclonic conditions because it:
· Self aligns to the roof profile, even when the screw is installed off-centre.
· Spreads the up-force load evenly across the surface of the cyclone plate.
· Eliminates the problems of chafing and single point contact with old cyclone plates.

Benefits & Advantages

· Significantly improves the roofs holding capability.
· Quicker and easier to install.
· Easier to store and handle.
· Self-aligns to the surface of the roof sheet when under uplift load.
· Tested and passed by the James Cook University Cyclone Testing Station .
· Lo-Hi-Lo approved.
· Provides a neater, more aesthetic roof appearance.
· Upper EPDM Seal ensures no entry of water between the top of the CORRI-LOK® plate and the underside of the screw head.
· Lower EPDM Seal ensures no water entry between the underside of the CORRI-LOK® plate and the corrugated roofing profile.
· ColorMatch® painted to match the colour of the roofing profile.
· Less likely to trap swarf and dirt beneath the plate, reducing the threat of corrosion.
