Electric seaming machine ESM-1 is used for closing double standing seam lock while roofing installation process. Electric seaming machine closes roofing lock much more faster comparing manual hand seamers.  Seaming machine has four pairs of rolls to close double standing seam lock step by step at first 90 degrees and after to 180 degrees. So you can really save your working time using our electric seaming machine ESM-1. Because if you close lock with hand seamers you have to close all the roof with first number of hand seamer and after to make second operation closing lock to 180 degrees with second number of hand seamer. Electric seaming machine makes it by one operation. There is a reason to use ESM-1 machine when you have big length panels and big roofing distances. Electric seaming machine helps to save your time on doing closing operations. Rolls of electric seaming machine ESM-1 are covered with special anti-slip material so it doesn’t slip while working.   The weight of electric seamer is not more than 30 kg, so it’s possible to work one person with the machine.   Before using our machine for closing double standing seam lock the beginning of panel has to be prepared: it has to be closed with first number of hand seamers. The length of prepared part of panel has to be enough to install the machine. After installing ESM-1 machine on the roofing panel you have to fix it with special fixation handle and after you can turn. The machine works from 220V electric lines. Very often our customers purchase electric seaming machine with roll former standing seam machine, floor decoiler. To get more information about our machines please contact us

Lock seam closing machine LSCM 1300x1.2mm is used for closing single lock on pipes with inside diameter from 80mm, maximum length 1300mm and maximum metal thickness 1.2mm. There is special moving closing mechanism on the machine which contacts with roll and makes possible to close single seam lock. Rotating handle operator of the machine transmits rotating moment through chain to sprocket and roll on closing mechanism. The roll of the machine can be from 76 to 90mm diameter depends on customer preferences. Roll of the closing mechanism has rough surface so it’s better contact with pipe’s lock and close it. During the work pipe doesn’t move but closing mechanism moves and close the pipe. Closing the pipe process with lock seam closing machine LSCM is the last operation during pipe production. You have to make pipe lock on the metal sheet before it and to make pipe from the flat metal sheet. You can use lock forming machine and plate roll forming machines for those operations. Only after you can close pipe lock with lock seam closing machine. And using swaging machine you can work with pipe’s ends to make it the way you want. The machine is manual so it doesn’t need any air or electricity to work. Our machine has more rigid base so it’s possible to work with thicker metal up to 1.2mm. It’s make our machine interesting for ventilation systems companies and chimneys production companies. As manufacturer of machine we provide 1-year warranty and after warranty service.

Round duct seaming machine RDSM 1300x1.2 is used for closing operation of round pipe standing seam lock in round duct systems, drainage, ventilation and air conditioning systems production. The machine finds its application in workshops of thin metal products production, manufacturing companies of ventilation and air conditioning systems, construction companies whose work is related to sheet metal and manufacturing of different diameter pipes.   To work with round duct seaming machine RDSM 1300x1.2 sheet metal pipe has to be pre-fabricated. To get blanks for pipe production you need at first to cut metal sheet in necessary dimensions using guillotine, plasma cutter, cut-to-length slitting machine or cross cutting knife from bending machine. After you have to make standing seam pipe lock on two parallels sides of blank. You can use bending machine, folding machine or ventilation lock forming HVAC machine to make this operation. Next step, using three or four rolls plate forming machine you can get round pipe with necessary diameter from flat metal sheet. And as final step to close lock of pipe with round duct seaming machine RDSM 1300x1.2 of our fabrication.  Round duct seaming machine RDSM 1300x1.2 has rotating roll which is driven by special rotating handle. With closed pressing mechanism of machine pipe is going between mechanism and roll so step per step pipe lock is closing. If thickness of metal is too high so closing operation can be done in two times.  Round duct seeming machine with such design lets to work with 1300mm pipes in one step and 2600 mm in two closing steps. As per request we can make machine with 1500-1600mm working length.   Machine can work with maximum metal thickness 1.2mm. In standard design we make machine with 90mm shaft diameter so minimum pipes diameter you can work with is more than 90 mm.  As per request we can make machine with shaft diameter less than 90mm but in this case maximum metal thickness would be less than 1.2mm Round duct seaming machine RDSM 1300x1.2 is equipped with special clamping eccentric mechanism which makes possible to adjust clamping force one time for necessary metal thickness and simply use clamping handle to close and open it without setting it up each time. It saves time while working with machine.   The machine is manual so it doesn’t need any air or electricity to work.

Standing seam hand seamers for double standing seam are used for closing locks on a double standing seam roofing panels. It consists from two tools:  First step hand seamer for bending 90-degree lock. Second step hand seamer for bending 180-degree lock. Before closing, the roofing panels have to be profiled with roofing seam machine and install on the roof. When panels contact each other, the side shelves of panels cover each other so there is one big construction with non-closed seams between panels. To close those seams and make them waterproof we recommend to use special closing tools such as hand seamers HS 1 and HS 2. The process of seam bending starts from a first stage hand seaming tool. This tool bends lock to 90 degrees. You have to lay it over the lock. You can start from the bottom of the roof or from the top of the roof and go down. Make sure that tool down is tighten to the seam, push your paddle all the way down, lift it up and sly down on the distance of the length of the tool, and continue down the paddle. It gives you a first bend. So now you can use number two hand seamer. Lay it on the seam. You can choose to start it from the upper or from the down part of the roof. You can make a first bend to 180 degrees.  So sly the tool down and finish the second stage of bending the lock all the way down to the bottom of the seam. Get it to the end.  You may kind of let it be free but we recommend to bend it a couple of times to hit that last edge of the seam real tight. So there is double locked seam closed.  The difference that makes our hand seamer much more better than other seamers is the ability to keep tight the material, not to let it slide while working.   You can use our hand seamers to close double standing seam locks on the straight roofs and on the roofs with radius panels.  We can also propose you to use our electric seaming machine, so you will be able to close double standing seam lock faster in one step operation.
