The Seam Makes The Roof
A new approach to roof performance was necessary due to new requirements in wind uplift resistance and testing methods. Other manufacturers came up with "band-aid" solutions by refitting their existing roof systems. But we invested in a totally new patented technology and method designed to meet and exceed the new requirements.
This new system allows an attractive appearance without compromising superior wind and water resistance. This technology is the reason why our metal roofs are the best in the industry for performance, reliability and cost efficiency.
Our proven, patented seam provides superior wind and weather protection under all roof loading conditions. The seam geometry and seaming methods virtually assure that your installed roof will perform as it was designed at minimum cost.
The TripLok™ seam is accomplished by seaming the entire seam with an electrical seamer. This seam will provide an allowable wind uplift loading of 48psf*.
- It's the only seam on the market to use the 360° + 90° seam, which:
- structurally isolates 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 dislodgment or 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.
While only required in extreme high wind regions, such as coastal regions, the QuadLok⢠seam is accomplished by seaming special roof zones with an electrical seamer. This seam allows uplift loads of 63 psf*, (or 97 psf over 2'6" purlin spacing).
Using the QuadLock seam, coastal regions with high winds won't need exterior clamps and brackets 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.
