Seam roofing is made from rolls or sheets of galvanized steel; non-ferrous metals can also be used in its production.
If you want to know how a seam roof is made, the video will clearly tell you about its features, advantages and laying technology.
Roofing received its specific definition due to the special connection of roofing seams, called "fold". There are folds
- self-latching,
- rolled by hand.
Advice. To improve the anti-corrosion properties of the roofing sheet, a layer of a special polymer coating is applied to it: pural, plastisol, polyester.
Today, almost all roofers use more reliable advanced roll decking technology, which provides the greatest tightness and durability of the roof.

When joining roofing rolls by means of manual seaming, a special tool for seam roofing is used.
Seam roll advantages:
- It is possible to use not only zinc-coated steel, but also coated with polymers of any color, which are more resistant to corrosion and have increased wear resistance.
- The high quality of a seam provided by the special technological equipment.
- They are produced in any length, which allows docking without cross connections, which ensures the absence of leaks.
- The entire installation process is fully automated, which makes it possible to carry out roofing work in the shortest possible time, without loss of quality.
- It is possible to use this technology on roofs of any configuration and complexity, even those with a large slope.
- Does not require special care.
Manufacturing machines
Seam roofing is produced on seam-rolling machines. They are mobile and able to work not only in the workshop, but also on the construction site.
The so-called folding machine is the most important equipment used in the production of roofing material.
This organization of work is the most profitable and justified, due to the fact that during installation there is no need to attract additional transport to deliver large-sized panels and a specialized room for their storage.

The maximum economic efficiency of mobile seam-rolling machines is achieved when they are used at facilities with a huge pitched area: pavilions, sports facilities, hangars and production workshops, which is due to the technological feature of manufacturing panels using roofing machines in the shortest possible time and the possibility of their direct joining using a semi-automatic seam-rolling machine .
The modern Russian market in a wide range represents the necessary equipment for seam roofing, both domestic and foreign, which in turn differs in cost, and also has various configuration options and its own technical characteristics.
High-quality equipment used in the production of roofing material is becoming more and more widespread on construction sites, thanks to its convenience, top performance and, of course, mobility.
In the manufacturing process, rolled metals are used, which, as a result of technological processing, are converted into roofing cards.
Copper Roof Coating Technology
The operation of connecting copper roofing sheets is carried out using double standing seams. You can learn more about this process from the video "Instructions for installing a seam roof."
The bending of sheets when installing a standing fold is taken equal to -20 mm for the first sheet, and -35 mm for the other. The height of the finished fold must be more than 23 mm high.
To ensure the reliability of the seam with possible temperature deformations of the copper roof, one of the edges of the sheet joined in the seam must be made with an inclination and providing a 3 mm gap.
When fixing roofing "pictures" on the base, clamps are used, which can be fixed and sliding.
Of course, it is better to see how the seam roof is installed - the video shows details about the features of such work.
