" Aratalan " Company uses junctions only by means of double folds. The given design is the most reliable in today's technologies. Seaming  roof is a metal roof in which joints of separate elements of covering (pictures) are executed by means of folds. A picture is an element of a roofing covering the  edges of  which are prepared for folding  junctions. The fold (folding  juncture) is a special kind of the seam formed when joining  metal roof with sheets .

Junction of  roofing folded pictures is carried out, as a rule, in a double standing lock welt . For maintenance of full tightness of junctions at installation of a seaming  roof, the fold can be condensed by silicon hermetic. The  attention is given to  quality of fastening sheets to lathing, which allows to avoid leakings and noise completely during  rain and  wind. Lateral long edges of steel strips , going along a slope, connect standing folds.
Seaming   roof  is carried out by modern way by means of   special electromechanical blocking  devices. At the installation of seaming  roof, the double standing lock welt  unlike a single lock welt, is by all means  reliable and safe . Use of a double standing lock welt and the  absence of through apertures on a surface of seaming roof, provides protection against leakings and  snow blowout  in the winter.
