The Oval Barbed Plate is for use with all VersiFlex™ PVC and KEE HP polyester-reinforced membranes. These plates are designed for use in mechanically attached PVC and KEE HP roofing systems, offering greater wind uplift resistance allowing higher wind speed approvals. In-house testing showed that the elongated edge of the oval plate better distributes the stress along the seam and improves splice delamination strength, resulting in higher wind uplift ratings.
