The OMG Purlin Fastener is designed for attaching single-ply membrane systems to structural steel purlins (12-18 gauge) in standing seam metal roof retrofit applications. The OMG Purlin Fastener is available in 3.75-in. to 8-in. lengths.
The OMG Purlin Fastener must penetrate the purlin a minimum of 1-in. This ensures a minimum of 1/4-in. thread penetration into the structural member. Using a screw gun with a maximum of 1800 RPM, drive the fastener through the purlin until a slight depression is seen around the plate.Prior to job start, contact OMG to perform a pull out test to determine deck suitability and pullout values.
Note: Caution should be taken not to overdrive the fastener causing stress plate surface to deflect more than 1/16-in. Prior to job bid, contact OMG to visit the job site and inspect the deck.
OMG CR-10 corrosion resistant coating passes the corrosion requirements of FM Approval Standard 4470 and ETAG 006.
Superior productivity. Superior performance.
