A Standing seam is a single folded or double folded seam. VMZINC uses profiling and seaming machines for the closure of longitudinal seam joints, which significantly reduces installation time.
The low height of the seams (25 or 32 mm) contributes to the modernity, lightness, and regularity of the roof and facade while highlighting its architectural purpose. When dealing with more complex designs this system presents a more technologically advanced appearance.

Transversal Junctions
When the length of the roof slope exceeds the maximum recommended length, it is necessary to join the sheets using transversal junctions. Several techniques exist depending on the pitch of the roof.
Step (or drip) - For pitches of 3° (5%) or more:
The step height will be a minimum of 8 cm for Standing Seam.
Double Welt - For pitches of 8° (15%) or more:
The double welt can be used in the standing seam technique for pitches of 15% and above. The minimum length of the overlap is 200 mm with a securing clip at the top. The overlap should be increased according to climatic conditions such as wind and rain.
Single Welt - For pitches > 25° (47%) or more:
The single welt or single lock cross-welt with an overlap of 50 mm can be adopted for pitches greater than 47% (25°) in the standing seam technique.
VMZINC recommends using the double welt over the single welt for standing seam techniques as it provides greater water resistance.
