Double lock standing seam system is a traditional technique applied to roofs. This technique can be machined or hand produced. It reflects the individual architect’s concerns for lines and shadows, producing designs that have a historical perspective.
These systems enable long strips of Zinc standing seam panels to be assembled by forming single or double folds on the up-stands. Due to the use of profiling and seaming machines for closing the joints, the installation time is greatly reduced, making this a cost-effective metal roofing and wall cladding solution. Concealed clips and fasteners provide a seamless appearance.
