The roof is made of corrugated board
Types of coatings
Profiled sheet after rolling mill enters the shop, where it is produced galvanically protective treatment. Protection is of two types:
- zinc coating involves the use as the working medium zinc salts. As a result of electrolysis the zinc is deposited on the metallic sheet, covering it with a continuous layer. This metal reacts poorly with oxygen, which ensures excellent protection of steel from corrosion. The more zinc has been spent, the more protection;
- aluminum-zinc coating is made of the same technology, but zinc salts are added to an aluminum salt. They are cheaper, so this cover over budget. In this case the degree of protection is reduced, which makes it necessary to do one more decorative coating of polymeric material and colorants.
The composition of the sheeting
The top color coating has more decorative function, since it is not very strong. However, it is able to amplify some basic protection.
Useful advice!One must be careful when installing a roof of corrugated board, as this may scratch the coating. Scratches are clearly visible on the surface, which will reduce presentable object.
corrugated sheets manufactured in different color variants
These coatings are applied to the paint layer, which may be of different colors. color name may be different from different manufacturers, but the most common are shades of red, brown, blue and green colors. You can find a bright orange, yellow and magenta versions of corrugated board. What is profiled to choose for the roof of his house, each host addresses according to their color preferences.
The dimensions of the sheet of corrugated roofing PC-20
Types of corrugated board for its intended purpose
Based on the application of the material, the following types of profiled sheet:
- Roofing (PC) is used only for the roof construction. It has a height profile of more than 20 mm and the wave height greater than 44 mm.
- The carrier (N) used in the construction of scaffolds, and various sales stalls pavilions, sandwich panels and ceilings. It has a wave height of 35 mm.
- Wall and bearing (HC) has a universal destination. Because it makes the supporting structures, veneer walls. Wave has a greater height (35-44 mm.).
- Wall (C) is used only as a covering material for walls. His profile from 6 to 35 mm in height.
The roof is covered with corrugated sheets
All kinds of corrugated board sheets are cut to standard lengths from 1.5 to 12 m. In this optional manufacturers can cut sheets of any desired length.
Useful advice!To avoid mistakes in the amount of material needed to close the complex roof, you need to buy 10-15% more. If the sheets in standard lengths, the excess can be returned to the store always.
Mounting metal roof
How to read the marking sheeting
As an example we can take the marking: NS35-0,5-750-12000. Decrypt it simply: NS35- means that the carrier sheet is a wall thickness of 35 mm. The second number is the sheet thickness - 0.5 mm, the third - width 750 mm, and the fourth - the length of 12000 mm. From these characteristics depend on the permissible load on the profiled sheet. There is a special load table for different types of corrugated board. The load capacity depends on the sheet thickness, the distance between the ridges, their height varies from 50 to 960 kg / m².
Taking into account that for the construction of roofs are used the sheets labeled PC, you need to decide what to choose for the roof decking.
corrugated sheets can be hidden and more complex forms of roofs
What to choose for the roof decking
Before you proceed to the choice of roofing material, you must understand the following important things which you should look for when buying:
- product labeled - "National Standard" (GOST) to buy rather than - "Specifications" (TU), as state requirements are always higher than the standards of the the manufacturer;
- when calculating the roof area must take into account the 200-millimeter tolerances;
- you can not buy too cheap not galvanized sheets that quickly rust and disintegrate under the influence of adverse environmental conditions.
Profiled roof
Useful advice!For roofing roof plate will fit only with a wave height of not less than 20 mm, with the more precipitation occurs in a particular area in winter, the higher should be the crest.
So what to choose for the roof decking of these options? Experts advise to make a choice based on region of residence, as the climatic conditions are decisive in the choice.

Among the main options of corrugated board, which can be covered by a roof, is isolated:
- PK20 - used in roofing in the region of moderate rainfall. It is necessary to batten device in increments of no more than 80 cm. The sheet has a working width of 110 cm.
- C21 - although this wall profile, but it can be used for roofing in the temperate zone. Step crates also no more than 80 cm.
- NS-35, 44 used in more severe environments, as they are more permissible bearing load.
Everything for the roof decking roofing used at home
Also used in roofing H-57, 750 (900) H-60, 75 depending on the required bearing load.
If the question arises, how the roof decking to choose is not necessary to remove from the accounts and such a parameter as the colors and decorative properties. After all, roofing, in harmony in color and texture with the other buildings on the site, looks much more attractive and creates the impression of integrity of the architectural environment.
The roof of corrugated easily equip dormers
For different types of roofs rules are slightly different. For instance, flat roofs are beginning to close the right edge. Mounting type tent roofs are performed simultaneously on both sides, and start from the highest places of the ramp.
Useful advice!Close the complex roof Decking better than metal. It does not require alignment of the length, which greatly saves material.
If properly decide which profiled roof to choose and put him in accordance with the requirements, you get a beautiful and reliable roofing.
