Profiled metal sheet is a versatile building material used for roofing, wall finishing, construction of fences and other purposes. The material is classified according to such a parameter as a profile for corrugated board, its size and shape, as well as the thickness of the sheet and the composition of the coating.
The use of corrugated board
Profiled steel sheet with a protective coating is called corrugated board in construction.
This material is very widely used in construction:
- For roof covering roofing works;
- For wall cladding (more often such a finish is used for household facilities);
- For the construction of canopies, hinged structures, fences;
- For the construction of fixed formwork in the construction of large construction projects.
Dimensions and marking of corrugated board
The raw material for the production of corrugated board is rolled steel, so the length of the sheets can be different and is determined, as a rule, by the requirements of the customer.
Advice! When ordering corrugated board for roofing, it is necessary to take into account not only the length of the roof slopes, but also the dimensions of the overhangs, since the roofing material must protrude beyond the slope eaves by at least 400 mm.
The width of the produced corrugated board for roof installation varies from 980 to 1850 mm. At the same time, it must be remembered that the useful width of the sheet is at least 40 mm less than the actual width, since the sheets are overlapped.
The thickness of the material depends on the thickness of the steel sheet used for its manufacture, it varies from 0.5 to 1.00 mm. The choice of thickness depends on the purpose of its use. So, in private construction, material with a sheet thickness of 0.5 or 0.7 mm is more often used.
It is customary to call the height of the corrugated board the distance between the extreme points of the wave. The larger this value, the more voluminous the roofing will look after do-it-yourself roofing work.
There are three main types of corrugated board:
- Bearing, marked with the letter H. This is a material that can withstand severe loads, it has stiffeners, and the profile height is usually more than 50 mm.
- Wall, marked with the letter C, this material is designed to perform decorative functions.
- Roofing, marked NS.This is an almost universal material that is used both for the construction of load-bearing structures and for decoration. But, most often, this type of corrugated board is used for roofing.
"Metal Profile" is one of the leading manufacturers of corrugated board
The production group "Metal Profile" specializes in the production of metal products. The assortment of the metal profile company includes corrugated board of various sizes and brands, sandwich panels, facade elements and related products.
The company offers the widest range of products with various technical characteristics and rich colors.
- Light weight. This facilitates the installation of the material, eliminating the need for heavy equipment.
- High degree of reliability. Due to the fact that the steel sheet has a double degree of protection (galvanization and polymer coating), this material has a long service life.
- Wide range of colors. This circumstance allows you to solve various design problems, choosing a material that matches the color. The polymer coating is resistant to fading in the sun, so the roof will retain its attractive appearance for the entire service life.
- Using corrugated metal profiles, you can create sealed roofing.
- Economic benefits of using corrugated board. The affordable cost of the material itself, ease of installation and long service life make this material cost-effective.
Components and accessories for corrugated roofing
When purchasing corrugated metal profile, you must immediately purchase additional components that will be required for the installation of the roof.
Naturally, you need to purchase them from one manufacturer, in which case they will exactly match the color of the base material, which will give the roof a neater and more holistic look.
The set of component parts is determined by the shape and design of the roof, so their list for individual projects may differ.
The list may include the following details:
- Ridge bar - a part installed on the upper intersection of the slopes (roof ridge).
- End strip - an element mounted on the ends of the roof.
- Valleys - a roof detail that is installed at the internal joints of the roof slopes. This element is complemented by planks of internal or external corners.
In addition, installation will require fasteners and materials for the installation of hydro, heat and vapor barriers.
Installation instructions for corrugated board
Installation work is carried out in several stages:
- Preliminary preparation. At this stage, the necessary measurements are taken, the material produced by the company metal profile is ordered - corrugated board and other necessary components. As a rule, the length of the slab is equal to the length of the slope, to which the length of the cornice is added plus another 40 mm. The required number of sheets is determined by dividing the length of the roof crest by the useful (not real!) Sheet width. When a fractional value is obtained, rounding is done upwards.
- It is recommended to cover roofs with a slope of at least 8 degrees with corrugated board.
- A prerequisite for proper installation is a waterproofing device.The purpose of these works is to prevent the penetration of moisture into the thermal insulation layer.
- Ventilation device. To remove condensate, it is necessary to arrange ventilation of the roof. The air flow must freely penetrate from the eaves to the ridge. To do this, ventilation holes are arranged at the highest point of the roof, and grilles at the ends of the roof.
- Insulation lining. Various materials are used as roofing insulation. Before laying one or another type, you must familiarize yourself with the manufacturer's instructions. So, for example, some rolled materials must be allowed to rest unfolded before laying. It is necessary to lay the insulation so that there are no gaps, for example, near the rafters.
- Sheathing device. In order to correctly choose the thickness of the purlin, it is necessary to take into account such a parameter as the wave height that the metal profile decking has. The minimum section of the boards that are used for the construction of the crate is 32 by 100 mm, while it is important that the cornice boards of the crate have a larger section.
- During the construction of the crate, it is necessary to install support boards in places of through holes. For example, at the site of the chimney, fire hatch and other through structures.
- The laying of corrugated board starts from the end of the house, while making sure that the anti-capillary groove of each sheet is covered by the next sheet.
- The sheets are laid along the line of the cornices, not forgetting the cornice protrusion (40-50 mm).
- The first sheet is strengthened with one self-tapping screw, placing it in the middle of the sheet in the profile deflection. Then the second sheet is laid, fastening the overlap near the eaves, screwing the self-tapping screw into the profile wave.
- Then both sheets are aligned (the cornice line is used as a guide) and reinforced with self-tapping screws with each other.
- 3 or 4 sheets are fastened in the same way.Then, after the final alignment, the sheets are strengthened to the crate.
- In the future, installation is carried out by strengthening the next sheet to the previous one, leveling and, only after that, attaching it to the crate.
Tips for handling corrugated sheets
- When storing sheets of roofing corrugated board, it is necessary to place bars under them with a thickness of 200 mm. The step of laying the bars is half a meter.
- To cut the plates, you can use scissors for metal or a circular electric saw. Abrasive tools are not allowed.
- Chips and sawdust formed during the processing of plates must be immediately swept away from the sheets.
- If scratches appear on the coating, it is recommended to paint them with spray paint to match. Also, you need to process the cut points.
- During installation, you need to walk very carefully along the corrugated board, stepping on the location of the crate. Moving along the sheet, you need to step between the waves, when moving across - to the place of the profile fold.
conclusions
Using the products of the metal profile company - corrugated board and other components, you can quickly and fairly cheaply make the roof of any house. The use of this material is beneficial from all sides: the coating is strong, durable, sealed and attractive in appearance.
In addition, the installation of corrugated board can be carried out on their own, since the work does not require the use of professional tools.
