STANDING SEAM

Standing seams are among the most common seam found in roofing and facades, and occur when the edges are folded away at right angles from the surface and then crimped (closed).

 

A single standing seam employing one single fold is seldom seen, as it’s susceptible to water ingress. The two most common types of standing seam are:

  • Double Standing Seam: Where the outer skin is folded over the inner skin, and then the entire seam is folded again, and
  • Angle Seam: Where the edges are folded and then the entire seam receives a 90 degree fold. This adds rigidity to the seam, preserving it’s lines. It also creates a thicker more eye-catching seam.
