Dutch Seam Difference

standing-seam-metal-roof-advantages-th-(1).jpgDid you know what makes the ATAS Dutch Seam panel different? It starts with the Dutch Seam roll former and in-line leveler. This is a stationary machine allowing for a factory controlled leveler with 18 forming stations and in-line applied masking.

The next differences are the premium options. To reduce the potential of visible oil canning, you can choose to have stiffening ribs, striations, and/or embossing.

ATAS’ modified Wind-Lok interlock design is another difference.  The clip at the low point allows loads to be imposed on the anchor clip, preventing rotation of the seam and providing stronger interlock during an uplift event.  Factory-cut edges are concealed within the panel interlock, eliminating edge creep.  After completing the panel interlock, panels can be easily moved into cleats at valley and eave conditions with the ATAS Dutch Seam panel.  With many other standing seam panels, the connection is friction fit and once it is “snapped” in place, it prohibits movement and adjusting.

ATAS offers a flat clip or a raised clip for installation.  The raised clip provides space for a hex head screw and Above Sheathing Ventilation (ASV). ASV spacer shims can be used along with the clips for additional ventilation.
