One of the most inexpensive, but at the same time high-quality and reliable building materials is a metal profile. This material can be understood as sheets of corrugated board or metal strips, which are usually used to create frames of various designs.
Due to the excellent performance characteristics, the metal profile, the sheet size of which allows you to easily and quickly mount the required structure, is often chosen as a building material for various fences or decoration of buildings. The metal profile is practically not affected by the environment, has excellent strength and rigidity, and also has a long service life.
Metal Profile Sheets
Cloths made of a metal profile are widely used for finishing both walls and roofs or for constructing a fence from a profiled sheet. At the same time, when choosing a material, the question often arises of which particular fabric is needed in a particular case. The fact is that a metal profile, the sizes of which are more than diverse, are distinguished into a bearing, wall and universal. And each of them has its own thickness and height of the corrugation, most suitable for a certain type of construction work and providing the required rigidity.
Using corrugated board
For the right choice of material, it is necessary to understand what the difference is between the types of corrugated board and in which 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 features of the installation of corrugated board, since during installation each sheet is overwhelmed with at least one stiffener on the previous sheet . Therefore, when calculating the required number of sheets for surface finishing or construction of the fence, this nuance must be taken into account. Depending on the type of profiled sheet, the dimensions of the metal profile for the fence can vary by 50-60 mm.
The length of the sheet depends on the wishes of the client, as a rule, the corrugated board in the production is cut into sheets with a length of 1.5; 1.8 or 2.0 m. However, it is possible to produce 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 profiles
Decking is divided into three main types, depending on their size, sheet thickness and height of the corrugation. The stiffness 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 a wall metal profile (corrugation dimensions of about 8-44 mm in height), used for decorating houses, arranging a light roof, as well as building fences from corrugated board.
- A universal metal profile with a corrugation height of 35-44 mm is used for ceilings, fences and sheathing of various structures for household purposes.
- The 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 permanent formwork in the construction of large-scale industrial structures.
Characteristics of wall corrugated board
This metal profile is marked with the letter “C” and is characterized by a small stiffener (corrugation). Strength, performance and material cost depend on this size. The smaller the rib, the lower all these parameters. The corrugation itself has a trapezoidal shape, which guarantees the stability of the canvas. Dimensions of the metal profile for the fence:
- A sheet with a rib height of 8 mm is the most economical option; thickness varies from 0.5 to 0.8 mm. The width declared by the manufacturer is 1.2 m, while the working one is 1.15 m.
- Decking under the brand name "C10" and "C20", that is, with a height of stiffeners 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 exterior decoration of buildings. The total width of such a sheet is 1.15 m, the working one is 1.1 m.
Universal and supporting professional sheet
“NS 35” already refers to the universal metal profile and is used for fences experiencing high wind loads, roofs and partitions. Due to the high corrugation of 35 mm and a sheet thickness of 0.4-1 mm, it is characterized by good strength and stability. The width of the sheets (claimed and actually used) is 1.06 m and 1.0 m, respectively.
The 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. The standard sheet width is 1.06 m, the thickness is 0.6-1.0 mm.
As you know, the approximate working width of the sheets of corrugated board 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 corrugation dimensions of which are 10-20 mm from a sheet with a thickness of 0.5-0.8 mm. Thinner, even at a high height, the corrugations will not have sufficient rigidity, too thick will cost quite expensive.
Metal profile for drywall constructions
The metal profile can be produced not only in sheets, but also in the form of a profile for creating structures that are lightweight and at the same time have sufficient strength and reliability. Most often, this material is used to create frames for plasterboard casing. With the help of such a metal profile, you can quickly build a partition or curtain wall in the room.
Such a metal profile for drywall, the sizes and shape of which differ depending on the purpose, are divided into rack (PS / CW), guide (PN / UW and PNP / UD), ceiling (PP / CD) and lighthouse. Each profile is used for its intended purpose, while all dimensions of the rails that are used for its production are interconnected. Since the rack of the frame during installation is inserted into the guide or ceiling profile, the standard dimensions of both types are performed taking into account this feature.
Typical sizes of metal profiles for drywall constructions
In the construction of various structures, such as partitions, niches or curtain walls, the approximate strength of the structure is primarily calculated. Depending on the required stiffness and ability to absorb a given load, it is determined which metal profile to use for drywall. Dimensions racks classified by the width of the back of the profile. As a rule, the choice begins 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, rack-mount is selected. Despite the fact that manufacturers claim the width of such a profile is 50, 65, 75 and 1000 mm, the actual size of the metal profile is 1-2 mm less. This is necessary in order to freely insert the rack into the ceiling profile. The depth of the rack is always 50 mm, the length is 3-4 m.
In addition to these basic materials, there is also an angled metal profile designed to protect the edges of drywall and construction angles, as well as a beacon - to align walls, floors and ceilings.
