One of the most inexpensive, but at the same time high-quality and reliable building materials is a metal profile. This material may mean sheets of corrugated board or metal slats, which are usually used to create frames of various designs.
Due to the excellent performance characteristics, the metal profile, the sheet dimensions of which allow you to easily and quickly mount the required structure, is often chosen as a building material for various fences or building finishes. The metal profile is practically unaffected by the environment, has excellent strength and rigidity, and also has a long service life.
Metal profile sheets
Sheets made from metal profiles are widely used for finishing both walls and roofs or building a fence from a profiled sheet. At the same time, during the choice of material, the question often arises of which canvas is needed in a particular case. The fact is that the metal profile, the dimensions of which are more than diverse, are distinguished bybearing, wall and universal. And each of them has its own thickness and corrugation height, which is most suitable for a certain type of construction work and provides the required rigidity.
Using corrugated board
For the correct choice of material, it is necessary to understand what is the difference between the types of corrugated board and in what cases it is preferable to use one or another metal profile.
The dimensions of the corrugated sheet have two width parameters: general and working. These values are due to the peculiarities of the installation of corrugated board, since during installation each sheet overlaps the previous sheet by at least one stiffener. Therefore, when calculating the required number of sheets for surface finishing or the construction of a fence, this nuance must be taken into account. Depending on the type of profiled sheet, the dimensions of the metal profile for the fence may differ by 50-60 mm.
The length of the sheet depends on the wishes of the client, as a rule, the corrugated board is cut into sheets of 1, 5 lengths; 1, 8 or 2, 0 m. However, it is possible to manufacture a profiled sheet to order: the desired height of the future fence will determine what size of the metal profile will be cut.
Varieties of metal profile
Decking is divided into three main types depending on their size, sheet thickness and corrugation height. The rigidity of the material depends on these parameters, due to which the metal profile is used for various construction and finishing works:
- The most common is wallmetal profile (corrugation dimensions are about 8-44 mm in height), used for finishing residential buildings, arranging light roofing, as well as building fences from corrugated board.
- Universal metal profile with a corrugation height of 35-44 mm is used for floors, fences and sheathing of various household structures.
- Supporting metal profile, the corrugation dimensions of which start from 60 mm, is most often used in industrial construction, for capital roofing, and also as a permanent formwork in the construction of large-scale industrial facilities.
Characteristics of corrugated wall board
This metal profile is marked with the letter "C" and is distinguished by a small height of the stiffening rib (corrugation). The strength, performance characteristics and cost of the material depend on this size. The smaller the edge, the lower all these parameters. The corrugation itself has a trapezoidal shape, which guarantees the stability of the canvas. Fence profile dimensions:
- Sheet with a rib height of 8 mm is the most economical option, the thickness varies from 0.5 to 0.8 mm. The width declared by the manufacturer is 1.2 m, while the working width is 1.15 m.
- Profiled under the brand "C10" and "C20", that is, with a stiffener height of 10 and 20 mm, respectively. It is this size of the metal profile sheet for the fence that is most often used due to the excellent ratio of cost and performance. As a rule, it is used for fences of various heights and externalbuilding finishing. The total width of such a sheet is 1.15 m, the working width is 1.1 m.
Universal and supporting profiled sheet
"NS 35" refers already to the universal metal profile and is used for fences experiencing increased wind load, roofs and partitions. Due to the high corrugation of 35 mm and the sheet thickness of 0.4-1 mm, it has good strength and stability. The width of the sheets (declared and actually used) is 1.06 m and 1.0 m respectively.
Bearing corrugated board in private construction is mainly used to create a capital roof. The small popularity of such a metal profile is primarily due to the rather high cost of the material. Standard sheet width is 1.06m, thickness is 0.6-1.0mm.
As you can see, the approximate working width of corrugated sheets is about 1-1.1 m. In this case, be sure to pay attention to the thickness of the material.
For private construction, it is recommended to purchase a metal profile, the dimensions of the corrugations of which are 10-20 mm from a sheet with a thickness of 0.5-0.8 mm. A thinner one, even with a large corrugation height, will not have sufficient rigidity, too thick one will cost quite a lot.
Metal profile for drywall structures
Metal profiles can be produced not only in sheets, but also in the form of a profile to create structures that are light in weight and at the same time have sufficient strength and reliability. Most often, this material is used to create frames forplasterboard sheathing. With the help of such a metal profile, you can quickly build a partition or a non-bearing wall in the room.
Such a metal profile for drywall, the size and shape of which differ depending on the purpose, is divided into rack (PS / CW), guide (PN / UW and PNP / UD), ceiling (PP / CD) and beacon. Each profile is used for its intended purpose, while all the dimensions of the rails that are used for its production are interconnected. Since the frame rack is inserted into the guide or ceiling profile during installation, the standard dimensions of both types are made taking into account this feature.
Typical dimensions of metal profiles for drywall constructions
When building various structures, such as partitions, niches or curtain walls, first of all, the approximate strength of the structure is calculated. Depending on the required rigidity and the ability to perceive a given load, it is determined which metal profile to use for drywall. The dimensions of the rails are classified according to the width of the profile back. As a rule, the choice starts with a guide profile, which can have a width of 50, 75, 100 mm and a standard depth of 40 mm, the length varies from 3 m to 4 m.
Depending on the selected guide profile, a rack profile is selected. Despite the fact that manufacturers declare the width of such a profile to be 50, 65, 75 and 1000 mm, the actual size of the metal profile is 1-2 mm less. This isnecessary in order to freely insert the rack into the ceiling profile. The depth of the rack rail is always 50 mm, the length is 3-4 m.
In addition to these basic materials, there is also a corner metal profile designed to protect the edges of drywall and corners of the structure, as well as a beacon profile for leveling walls, floors and ceilings.
