Condition: new, Year of construction: 2025, The segment folding machine SM 2020x1.2mm is a machine for bending different elements from the metal sheets with maximum length 2020 mm and maximum thickness 1.2 mm. Can be equipped with third bar segmented. Usually folding machines are used for producing roofing elements, ventilation elements, drainage system elements etc. But segment folding machine SM thanks to special segmented bars gives the opportunity to bend boxes and façade cassettes in addition to standard bending elements. Segmented bar is a bar consisting of parts with different lengths. So you can adjust it to the length you want and bend boxes around this segmented part. We produce three models of segment folding machine SM: Segment folding machine SM-1270 x 2mm Segment folding machine SM-1550 x 1.8mm Segment folding machine SM -2020 x 1.2mm Those segment machines have two bars segmented: The upper bar and rotation bar. The upper bar has a 135 degrees’ angle, so it’s possible to bend elements with maximum bending angle 135 degrees The standard set of segment folding machine SM includes: The folding machine SM, tempered segments, angle measuring device, the four position angle limiter, two segments with side cuts, multifunctional acceptance table. As an additional option you can get cross cutting knife for the segment sheet metal bending machine. The maximum thickness of metal the knife can cut is 0.8mm steel. The segments of the folding machine are tempered and the rigidity of them is about 30 HRC. So it lets the opportunity to bend thick metal in any part of bending machine without any damage. We have started producing of segment folding machine SM since 2003 y. So we have a great experience in segment machines producing and can propose you a perfect solution for you business.

Condition: new, Year of construction: 2025, Double standing seam roofing machine F3 is used for making double standing seam lock for the roofing panels that are used for installation of the double standing seam roofing. The double standing seam roofing is widely used because it’s impossible for the water to get under the closed double standing roofing panels in the places of their contact with each other, thanks to lock’s special shape. The special shape means that double standing seam panels cover each other in the places of their contact, and after their installation on the roof it will be closed using special double standing seam closing tools (manual tool for closing double standing seam lock and electric machine for closing double standing seam lock). The advantage of this Standing seam machine is possibility to change the width of the standing seam roofing panels in very simple way. There’s a special screw at the one side of this standing seam machine and turning it around the operator can change the width of the panels. So the adjustment of the standing seam roofing machine doesn’t take a lot of time for the operator and let him use his working time more effectively. This double standing seam roofing machine is good for making double standing seam panels from different kinds of metals (galvanized steel, steel coated with copper, zinc, titanium, etc.) This standing seam roofing machine has six pairs of rolls which form the shape of the double standing seam roofing panels. This machine could be produced for using with 220V or 380V electric lines. You can also purchase with roofing seam machine: additional pair of rolls for making ribs on the roofing panels; additional pair of rolls for making bended panels with a big radius of bending; Ppjdpfx Akjhz Twwerjr cutting knife; metal decoiler; manual tool for closing seam lock; electric machine for closing seam lock; sheet metal cut to length machine; It’s easy to work with our double standing seam roofing machine right on the place of the double standing seam roof installation, thanks to the small weight and not huge sizes of this standing seam machine. It’s let the owner of this roofing machine to save money not spending them on renting additional places for making double standing seam roofing panels, storage them and transport to the place of their installation. Our enterprise has started producing of this double standing seam roofing machine since 2005 so we have great experience in doing our job and can propose you a great solution for your business. To get more information about the price of this double standing seam roofing machine and the way it could be delivered to your location just contact us. We will give you all the information you need.
