VMZINC's Double Lock Standing Seam technique can be machine or hand produced. It reflects the individual architect’s concerns for lines and shadows, producing designs that have a historical perspective.
Due to the use of profiling and seaming machines for closing the longitudinal standing seam joints, the installation time is greatly reduced, making this a cost-effective solution, particularly for very large roof surfaces.
USES & APPLICATIONS
- Large roof surfaces
- Structures located in regions of harsh climate, which are often subject to snowfall (mountainous or continental climate), strong winds, and heavy rain.
- High tech appearance
- High lightness
- Quick installation
- Low height of the seams 1” (25 mm) and 1 1/2” (38 mm)
- Available in the following color finishes: natural, QUARTZ-ZINC, ANTHRA-ZINC, PIGMENTO red, blue, green, and brown.
- Theoretical thermal expansion coefficient of 1/64''/ft for 212ºF temperature change (22.mm/mm for 100ºC change).
- High wind resistance in extremely windy areas.
- It is possible to modify the number of fixing clips required according to the prevailing climatic conditions.

- Examine substrates, areas, and conditions for compliance with requirements for installation tolerances, metal wall panel supports, and other conditions affecting performance of work.
- Verify that substrate is plumb, sound, dry, smooth, clean, sloped for drainage, and completely anchored, and that provision has been made for wall drains, flashings, and penetrations through metal wall panels.
- Examine primary and secondary wall framing to verify wherther or not purlins, angles, channels, and other structural panel support members and anchorages have been installed correctly.
- Prepare written report, listing conditions detrimental to performance of work of this section. Submit copy of report to architect.
- Examine roughing-in for components and systems penetrating metal wall panels to verify actual locations of penetrations relative to seam locations of metal wall panels before wall panel installation.
- Install metal wall panels in orientation, sizes, and locations as indicated on the drawings.
- Install metal wall panels plumb, level, square, true to line, and within installation tolerances.
- Install metal wall panels perpendicular to girts and subgirts, unless otherwise indicated.
- Anchor metal wall panels and other components of the work securely in place, with provisions for thermal and structural movement. Do not use a torch to field-cut metal wall panels.
- Fasten metal wall panels in accordance with manufacturer’s instructions. Panels to be installed on vertical lines 28cm on center. Flash and seal metal wall panels with weather closure edges and at the perimeters of openings.
- Install flashing and trim as metal wall panel work proceeds. Fasten flashings and trim around openings and similar elements.
- Maintain metal wall panels in clean condition during installation. Remove protective film within 90 days of installation.
