ULTRA SEAM
Standing Seam Panel

UL 90 Rated
ASTM E-1592

Ultra Seam US-175LS (Lok Seam)
As ribs of adjacent Lok Seam panels slide together, enclosing the concealed clips, indents in the Lok Seam panel ribs slip into place with a positive metal to metal lock. In turn, the enclosed clips positively secure the adjacent panels to the roof structure. Seams require no machine closing, yet are continuously and securely locked in place. By eliminating the need for mechanical seaming, installation time and cost can be greatly reduced. Also available in 1-1/2" rib height (US-150LS)
The US-175 Has a rib heights of 1.75".
