MP 20 decking is considered an ideal building material. It is convenient, practical for installation, very strong and durable.
Production of corrugated board
This corrugated board is manufactured, like other brands of galvanized metal sheets. Steel is delivered to the plant in rolls, which are unwound by special automatic machines. The material is then placed on a rolling table that transports the steel to rollers that convert the smooth metal into corrugated surfaces.
After the roller processing is completed, the metal profile is sent for cutting and painting. First, the metal is cut to the required length. Then it is galvanized (when the steel is supplied in a non-galvanized form) and sent to the painting shop, where the galvanized MP 20 corrugated board is processed. Processing can be done in 2 ways:
- coloring using high-frequency electric current (this method is more reliable);
- high-pressure powder coating.
Professional flooring MP 20 roofing - painted material. Manufacturers offer many color options: aluminum, black, red, blue, white, brown, etc. In addition, it has more pronounced resistance to temperaturechanges and corrosion, has a more presentable appearance. However, the cost of a painted profile is much higher than usual, for this reason, if this factor is not very important to you, then you can purchase unpainted material, and then process it yourself.
After such processing, the colored material is covered with a protective film that helps it retain color and protect itself from corrosion. Only after that the product is sent for sale.
Sizes
Professional flooring MP 20 is produced with a width of 1150 mm, taking into account the overlap with adjacent sheets, the useful width is 1100 mm. Wave profile height - 20 mm.
Profiling MP 20: characteristics
Profiled sheeting is a building material that has a coating designed for walls, roofs, partitions and the construction of small buildings. The designation "MP" indicates that the metal sheet is universal, and due to its good rigidity and low weight, it can be mounted on almost any surface. The number 20 is the height of the corrugation.
Features
The sides of the material are polymer or zinc coated and can be laid on either side. Manufacturers recommend placing the narrow top of the wave up, and vice versa in the process of wall cladding. A similar feature is also taken into account during installation on the roof or when used for cladding.
Scope of application
Professional flooring MP 20 is used:
- when erecting structural elements of light metal structures - change houses, garages, pavilions;
- in the process of roofing with lathing steps no more than 40 cm;
- for panel fences;
- for frames of fast-building structures;
- for metal gates and fences;
- for walls of all-metal buildings of small area;
- as a base for thermal insulation sandwich panels;
- as cladding panels for main walls;
- for internal partitions of buildings.
Dignity
- Flexibility. The material is often used for mansard, broken, hipped and other "wrong" roofs.
- Long service life. With normal care over 50 years.
- Accessibility. Decking is inexpensive, unlike other similar coatings.
- Relative ease. Any foundation can easily carry weight up to 8 kg.
Thanks to the listed advantages, MP 20 professional flooring has mostly positive user reviews.
Flaws
However, even such an excellent material as MP 20 corrugated board, according to reviews, has some disadvantages:
1. The profile height is not always convenient, for example, it will not be enough to cover complex roofs, material with a larger corrugation may be required.
2. The material may not tolerate stagnant water, that is, it is not recommended to install the profile on a flat roof or in the absence of a drainage system. Here, eitherimproved vapor and waterproofing system, or 2-sided corrugated board.
3. Roofing decking MP 20 needs to be periodically cleaned from snow, leaves, dirt, otherwise the integrity of the coatings may be damaged.
However, in other aspects, this particular material is the best solution for covering the facade of a house, arranging roofs, covering fences, lining utility buildings and other construction work.
Despite the shortcomings, MP 20 corrugated board reviews are generally good.
Installation of corrugated board
The procedure for fixing this material to the roof does not imply anything special, it is installed on the crate in a similar way as other materials. You should read the recommendations of professional builders about installing a profiled sheet:
1. Mounting should always be done with an overlap, due to which the connection will be more rigid.
2. Fastening should be done with screws, not nails.
3. To carry out the laying of roofing and wall corrugated board MP 20, drawings are required that will allow you to count the number of sheets and connecting products. The installation diagram also helps to calculate the rigidity of the structure.
4. Sheets are not joined very often in order to avoid a decrease in rigidity. Five screws are often sufficient - one in the center and two at each corner.
5. It must be remembered that machines that process polymers are quite expensive, it is for this reason that beforewhen purchasing corrugated board, it is advisable to negotiate with enterprises regarding the processing of sheets on equipment.
