Corrugated roofing sheeting - metal, not afraid of corrosion
Stiffeners play a significant role in construction, they provide reliability to many structures in areas with a high degree of load. One such section is the roof. She constantly checks for strength of the stormy wind, tries to break through the hail, deflect snow drifts. It is clear that the profiled roofing, which consists entirely of ribs of rigidity, is one of the most reliable materials.
For laying on the roof, you should choose a slate sheet with a corrugation above 20 millimeters.
This material is a sheet metal of a complex corrugated profile( there are other sinusoidal forms, for example, a wave), due to which it has an excellent resistance to bending along the longitudinal axis.
Corrugated corrugated board is coated with galvanizing, it is not uncommon to cover the sheet over a zinc layer with a polymer film, most often a colored .Actually, the protective functions of the polymer coating are small, it is done only as a coloring material, but the service life of the roof is markedly increased.
What are the criteria for choosing a roof from corrugated board?
Anticorrosive coating is wonderful, what is needed to ensure the durability of the roof, but in fact it is not one of the decisive factors for the choice of corrugated board. What else attracts people in this material? Firstly( or, given the characteristics described above, perhaps, in the third place) - the ease of the material.
Like many other modern roofing materials, corrugated board with a reliable support can easily be laid by one person. And when transporting the material, this is a very advantageous quality, which saves a lot of money on transportation costs. Undeniable is the characteristic, like the ease of processing - corrugated board is easily drilled, sawed and assembled into finished structures with the help of standard fasteners.
By the way, about the assembly. Work with profiled sheeting does not require any special training, and the roof of the profiled sheeting, which is one of the most popular educational materials, is collected even with complete lack of experience, with bare enthusiasm.
And even if an error is made, it is even easier to dismantle than to assemble the desired structure, whether it's a roof or a fence made of corrugated board. The latter, of course, does not interest us, it is mentioned only as a fact that the slate sheet is used in various spheres.
Profiled sheeting zinc-coated roofing - laying calculations
As with any other material, galvanized roofing profiled sheeting requires accurate calculations of the area to be covered so that the roof is perfectly fitted. It is best if the sheet of galvanized iron is unbroken, then the roof will be more durable, without unnecessary seams.
However, it should be taken into account that the corrugated board is sold by sheets, the maximum length of which does not exceed 6 meters, large dimensions are inconvenient for the transport of .However, you can order a sheet directly at the place of manufacture, then its length will be exactly what you need - from the ridge to the overhang, to which you need to take away 4 centimeters.
Having dealt with the width of the roof, we turn to the calculation of its length, for which we need to know the number of sheets that will be required for styling. The dimensions of the corrugated board are most likely known to you, therefore, you know the width of the sheet. How many will go on overlaps, you can not count. So, we measure the length of the cornice, in this there is nothing complicated. Why focus on the cornice? Roofs are of complex shape, for example, trapezoidal, so we need the longest part of the roof.
So, the resulting length of the cornice is divided by the useful width of the profile, and the result is rounded to the nearest whole number. For each type of roof, especially for complex shapes, the calculations are purely geometric, in accordance with the similarity with one or another of the figures according to the previously made scan of the roof.
