Three Seaming Systems For Standing Seam Metal Building Roofs

The Zeus-Shield™ Standing Seam Roof System for Steel Buildings Uses Three Roof Seaming Methods:

1. The “RollLok” seam does not require an electrical seamer to complete the roof. All that is required to seam the “RollLok” seam is a hand seamer, used to crimp the seam at clip locations.  The “RollLok” seam provides greater uplift loads than any of the existing no-seamed metal roof systems.
2. The “TripleLok” seam is formed using an electrically powered seamer that forms a seam that will resist higher uplift loads than any seamed metal roof system on the market.
3. The “QuadLok” seam is used in very high wind load portions of seamed roofs for pre-engineered steel buildings or metal buildings systems where other roof systems would require narrower 2'-6" purlin spacing, narrower 18" wide panels, thicker 22 gauge panels or a combination of all of these options.

The “QuadLok” seam is formed by seaming over the “TripleLok” seam to further tighten and form an additional strengthening bend in the seam. The “QuadLok “ seam is typically used in areas of the roof that require extreme uplift resistance such as the corner and edge zones of roofs in high wind areas.
