Metal tape is made of galvanized steel with a colored polymer coating that imitates natural tiles, a universal nature of use. Such a roof is easily mounted on any surfaces with a single restriction – the angle of slope of the slope of the roof surface – should be at least 14 degrees. Thanks to the use of new chemical technologies, corrosion resistance is 2-6 times higher than a similar indicator of the usual galvanized sheet.
Another important advantage of the metal tile is the slight weight of the material, so not only the load on the rafter system is significantly reduced, but also on the design of the building as a whole. In addition, all fasteners are sold together with metal tiles, and directly the roof installation does not require high qualifications of masters. Therefore, in many cases, laying is carried out by owners of structures on their own. Which significantly affects the reduction of material costs on the device of the roof.
Another important factor affecting the quality of the material is the type of coating of a steel sheet. Today, several types of coatings are distinguished: – PVF2 (PURAL) is used to facing roof facades; – PVC 200 (plastisol) is a mild and resistant to damage to the coating of metal tiles; – PVC 100/100 (polyester) – basic material for the production of drains and high -quality metal tiles.
Depending on the purpose and type of coating of metal tiles, various roofing works of the rates are required for which may vary somewhat. Therefore, having decided to entrust the installation of metal tiles with a construction team, it is necessary to determine in advance the goals and category of the coating in order to correctly compose an estimate and know the upcoming expenses. When cutting sheets, it is strictly forbidden to use an angular grinding machine.
The more pronounced the relief of the roof, the less often there should be the step of the crate. If you decide to lay new material, then the profile sheets are attached to the old trim of the roof with a slight modification. In this case, the sheets are attached with screws of 4, 8×35 mm of stainless steel. They should be screwed to the rise from the pressure of the rubber sealing ring by 1 mm above the puck itself. Do not forget that the roof set also includes accessories necessary to create a durable and beautiful roof, requiring additional attention during installation.
