STANDING SEAM ROOF SYSTEM
EXCELLENT AESTHETIC APPEARANCE BACKED BY SUPERIOR STRUCTURAL INTEGRITY.
A proven, patented seam – utilizing the VS-216 panel system technology – 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 TripleLok™ seam is accomplished by seaming the entire seam with an electrical seamer. This seam will provide an allowable wind uplift loading of 48 psf.*
- 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. - isolates the seam sealant from dislodgment or separation during
severe wind loading, thereby assuring a water resistant seam throughout the life of the roof.
- structurally isolates the seam from the effects of severe wind loading
- Easy installation: all that is required is the placement of the 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 1592 tests
