The Seam Makes The Roof
Recent advances in wind uplift resistance conditions and testing methods have called for a new approach to roof performance.
While other manufacturers still react to these advances by modifying their existing roof systems with little change in their solutions, we have entrusted a totally new patented method and technology that is designed to meet and exceed these new requirements.
Now you can have a beautiful appearance in a standing seam roof without risking superior wind and water resistance.
The advanced technology behind our seaming system is the reason why our metal roof is the best in its class for performance, reliability and affordability.
Our proven, patented seam provides wind and weather protection under all roof loading conditions. The seam geometry and seaming techniques assure that your installed roof will perform as it was designed.
The TripLok™ seam is achieved by seaming all of the seam with an electrical seamer. This seam will provide an allowable wind uplift loading of 48psf*.
- The only seam on the market to use the 360° + 90° seam, which:
- structurally confines the seam from the effects of severe wind loading by placing load resisting bends between the seam and the stresses of panel deflection.
- eliminates the possibility of seam sealant separation during severe wind loading, thereby assuring a water resistant seam throughout the life of the roof.
- For fool-proof installation all that is required is the placement of an electrical seaming machine on the seam to begin the seaming process. It's virtually impossible for the seamer to run off the seam until it comes to the end of the panel or is removed by the operator.
The QuadLok™ seam is only required in extremely high wind areas such as coastal regions. This seam is accomplished by seaming special roof zones with an electrical seamer, when required. This seam will provide an allowable uplift load of 63 psf*, (or 97 psf over 2'6" purlin spacing).
By using the QuadLok seam, the perimeter conditions of roofs in high wind coastal locations can resist wind loads without exterior clamps and brackets that most other roof systems require to meet the Zone III uplift loads.
The QuadLok seam is the only seam on the market that provides higher uplift resistance with 24 gauge panel than all other roof systems using 22 gauge panels.

All of the above seams and load tolerances are calculated using ASTM E 1952 tests.
