Name, perhaps you would not say anything separately. Well met somewhere somehow sometime by mistake. And actually, you can not even imagine what the roofing sheet, folded roof! It's simple: it is the most convenient and most efficient in the use of roofs. Called the folded roof of sheet and rolled galvanized steel (as-coated, and without it), and a roof made of nonferrous metals. Seamed roof - it's metal roof, in which the compounds of individual elements of coating (painting) made with folds. Painting - the element of roofing, whose edges were prepared for the seam compound. Seam (seam connection) - view the joint formed when the compound sheet metal roofing. Distinguish seamed connection recumbent and upright, single and double. Long side edge bands were going along a slope, band standing seam, and the horizontal - bumps. Folds are satisfied (rolled), or manually by special tool or a modern way - with special electromechanical devices seamers. Today there is another kind of rebate - samozaschelkivayuschiesya. Connect them with each other, without using tools. The most leak-proof and waterproof is a double standing seam - a longitudinal joint, protruding above the plane of the roof between two adjacent roof paintings, the edges of which have a double bend. To date, folded roof in Western countries is mainly performed using the double standing seam. In Russia, the leading firms that use Western equipment, also switched to this type of compound roof paintings. And today's construction market, a large number of companies offering the device on the roof with modern technology. Unfortunately, to check whether they are really modern, in advertisements is not easy. The complexity of the roof structure is in a high percentage of the hidden works, errors that occur only in the operation of the roof. Known examples where the construction of roofs unprofessional singers led to the need for complete replacement of the roof covering. When the device roofs on modern (rolls) of technology is very important to competent performance of adjacency. Unfortunately, to date, developed types of sites is clearly insufficient, especially for the reconstruction of buildings in the historic building. Therefore, the invaluable experience of specialized construction companies, which have long been working on the roll technology, and have their own technical development, literacy specialists, which gives them the opportunity to perform roofing work with high quality. Often such companies, having a data bank of various design decisions, can provide expertise as their partners and designers. There are a number of indicators by which we can determine how this company can be trusted not an easy task on the device of the roof. First of all, it's the license, registered trademarks, patents, letters of reference customers and photos of completed projects. The key to the reliability of the company are as guarantees for work, and penalties for marriage and for the failure to date the work is completed. Customer must advance to ensure availability of certificates for materials to be used in the work, their absence could lead to large losses. If all the above listed documents are available, then it is a good base to start cooperation. Device seam roof One of them is a staircase consisting of simple wedge-shaped steps, which rely for its wide end of the surrounding walls, and narrow - on average supporting pillars. Another option - single stage konsoleobrazno protrude from the middle of the reference monolithic column. Such a ladder can be far away from the walls (even in the middle of the room). The third type differs from the previous lack of internal reference column. Stage simply be incorporated into a curved (concave) wall. Recommended roof pitch when using Folding technology - more than 140. At lower slopes of the roof (from 70 to 140) is mandatory unit solid foundation, and the application of double folds, packed with silicone sealant. space. Violation of the required parameters leads to the formation of condensation on the inner side of the paper, which also can cause premature corrosion. Used fasteners such as nails, screws, wire, klyammery, must necessarily be made of galvanized steel. This is to ensure that they have the same lifetime as the coverslip surface. To date, traditional technology devices seamed roofs of sheet metal (using a special hammer) superseded by a new, modern technology, the device of the roof of rolled metal (with power tools), which improves the quality of welds and significantly increases the productivity of roofers. Consider these two technologies in more detail. Traditional technology unit of the roof of sheet steel, requires highly skilled roofers. Work is done in several stages. First step: making pictures for the average coating roof slopes, eaves, wall troughs, razzhelobov. For the first blank paintings done directly on site preparation of necessary forms and sizes (from drawings of the future of the roof). Steel sheets to mark out the details with instruments and tools are applied to a metal marker. Then the steel sheet, depending on the thickness and cut various kinds of scissors and join bed-fold in the picture, the length of slope, the lateral edge bent, ie, make the workpiece to perform the standing seam. Second stage: the picture up on the roof and connect their sides of each other standing seam (often single). Then the pattern is fixed to furring narrow strips of steel - klyammerami that one end of the lead up to a standing seam when they bend, and the other fastened to the timber battens. Thus, a high-quality roofing, without any technological holes. Openings in smoke and gas pipes, including ventilation, covered with aprons made of galvanized steel. Galvanized roofing can not be painted with conventional enamels, nitro - and oil paints. For this purpose there are special paints, although they are quite expensive (about 1 $ / m2). Roll the technology is so called because roofing painting made directly on the construction sites of metal, delivered in rolls and can be virtually any length. It is this avoids the transverse (lying) folds and, consequently, the main places of leaks. Connection of roof painting, as a rule, in a double standing seam. To ensure complete impermeability of the compounds, as mentioned above, the seam can be sealed with silicone sealant. To use the roll technology requires modern equipment including machine tools for metal cutting, bending and special sealing machines and other roll technology is the most progressive and allows you to organize the modern seamed roof as from a simple galvanized steel coils and galvanized with a polymer coating. The advantage of roll technology is: the possibility of using not only galvanized steel, and polymer-coated steel, which is compared with the first more corrosion - and wear-resistant, and therefore more durable, ensuring a high degree of sealing cover the expense of seamer in the stand-up double seam of longitudinal joints adjacent roofing sheets (usually in the complete absence of horizontal lying rebate), the method of the device of the roof is almost silent, which is extremely important when working in congested areas, the ability to use technology for the roofs of any slope, any irregular shape and any size, mobility of some types of equipment , which allows you to perform all work not only directly on site, but even directly in the attic, water drainage system (gutters, rectangular and half round gutters, elbows drainage system) is made from the same materials as the roof covering.
