General information

Standing seam is a single folded or double folded seam.

The use of profiling and seaming machines for the closure of longitudinal seam joints 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.

The Standing seam technique is particularly suitable for very large roof and facade surfaces and for structures located in regions of harsh climate, which are often subject to strong winds, heavy rain and snowfall (mountain or continental climate). 

Areas of application

Suitable for both renovation projects and new buildings - Can be installed horizontally and vertically.

    The support must be :

    • Rigid and continuous.
    • Meet loading requirements in conformity with a minimum pull out strength of 50 daN for each clip.
    • Rest on at least 3 bearing structure elements.
    • Have no protruding elements on the support.
    • Transversal junctions

    Fixing System

    The L profile of the preceding Standing seam panel and the clips that have been fastened to the panel and fixed to the structure are covered by the U of the next panel, avoiding stresses and lateral traction.

    Clips have a dual function: 

    • Allowing free expansion of the metal.
    • Ensuring the mechanical resistance of the entire roof.

    The clips from VMZINC are made of 304 stainless steel. The thickness of the fixing clip is 0.5 mm.

    The sliding clips have a moving component, which is 0.4 mm thick, and a 70-mm long slot to allow free movement of the panel from VMZINC under expansion and contraction.

    The sliding component of these clips must be carefully positioned within the slot at the time of installation. In general, the sliding component is positioned in the middle of the slot.

    The clips resistance to tearing is 50 daN.

    It is recommended that screws be used to secure the clips.

    Three screws per sliding clip is recommended. The use of nails offers significantly less resistance, but in the event of using nails contractors are advised to use ring shank nails.
