Square-Rib Roofing Cyclone Assembly

Buildex are pleased to announce the arrival of SQUARE-LOK® the all new cyclone assembly for square-rib roofing profiles.

SQUARE-LOK® has a large contact area with the roofing profile and self-aligns with the roofing profile, even when installed off centre. This spreads the up-force load from heavy winds evenly across the surface of the cyclone plate. It eliminates the problems of chafing and small contact area of conventional bonded washers systems.

Advantages & Benefits

• Significantly improves the roof-holding capability.
• Quicker and easier to install.
• Self-aligns to the surface of the roof sheeting
• Tested and passed by the James Cook University Cyclone Testing Station.
• Includes a double washer system, an upper and lower EPDM Seal preventing water entry between the screw head, cyclone plate and roofing profile.
• Provides a neater, more aesthetic roof appearance.
• ColorMatch® painted to match the colour of the roofing profile.

Testing

SQUARE-LOK® has been tested by the James Cook University, Cycle Structural Testing Station in report TS570. Cyclic fatigue load trials were performed at 10,000 cycles as described in clause 3b of the Northern Territory BCA appendix. Lysaght 0.42mm BMT Trimdek cladding was attached to 1.6mm cold formed steel sections, over 1200mm spans, for a permissible stress design load of 4.2kPa.

SQUARE-LOK® successfully completed the required 10,000 load cycles. The roofing resisted the proof load, with some evidence of cracking observed from the fixing locations.

SQUARE-LOK® Square Rib roofing cyclone assembly is available as:

• 14-10 x 65mm HWH Type 17
• 14-10 x 75mm HWH Type 17
• 14-10 x 50mm HWH Metal Teks®
• 15-15 x 55mm HWH Metal Batten Teks®

In a choice of a Class 3 or Class 4 corrosion resistant finish.
