RollLok Seam
Our SL-324 standing seam features the RollLok seam, which is crimped at the panel clips, offering superior weather tightness and wind uplift ratings compared to existing snap-together panels. Achievable with a manual crimping tool. No electric seamer is required.
TripleLok Seam
The TripleLok seam, achievable with an electric seamer making a single pass, provides enhanced security by seaming in both directions (upslope then downslope). Essentially, it is a double lock seam rotated 90 degrees.
QuadLok Seam
For ultimate performance, the QuadLok seam is created with an electric seamer making two passes along the seam—up the slope, down the slope, and over the same seam. This QL seam is a TripleLok seam rotated down 90 degrees for maximum integrity and security.
