Finishing work in the apartment can not be done without frame-and-skin designs. Thanks to the installation of such structures, the work becomes more intensive and reliable, because the manufacturers of metal profiles have taken care of the quality of work. However, choosing a metal profile is necessary skillfully, with knowledge of the matter. How should I choose a metal profile for finishing work?

Skeleton-sheathed structures, what is it?
Modern intensive technologies, used throughout the decoration work, can not be imagined without skeleton-sheathed structures. Skeleton-sheath structures for finishing works of apartments are used for load-bearing and hinged elements.
Undoubtedly, the advantage of the technology of frame-skeleton structures is the speed of erection and a fundamentally new approach to the prefabricated structure. The main element of the frame structure is, and we must give credit very successfully, the profile is metallic. Metal profile in structure:
• eliminates the restrictions on the placement of heat, sound insulation
• allows solving heat and energy saving problems
• Improves the strength characteristics of the skin.
Depending on the requirements, the frame-skin designs can be single-layered or multi-layered. The solidity of the structures for finishing works, as well as the overall dimensions, are calculated at the design stage. The installation of frame structures is done manually, so the choice of metal profile and its dimensions require certain knowledge. By what criteria is it necessary to evaluate the quality of the metal profile for the structures?
Of course, the quality of the metal profile must be carried out according to the following criteria:
• the main purpose of the profile
• fabrication material
• Fixing base.
Therefore, intending to install a frame structure, it is necessary to justify the expediency of its installation.
Types of metal profiles
By purpose, the metal profiles are divided into the following types:
• Rack PS profile
• profile guide PN
• Ceiling profile PP.
The industry produces metal profiles in convenient sizes of 3 and 4 meters in length.
The endings of the walls of some metal profiles are equipped with technological holes, thanks to which it is possible to mount the wiring inside the cladding and partitions.
rack-mountable PS profile
The rack galvanized profile has a characteristic C-shaped configuration. It is universally used as the main racks of skeleton skins and serves as a partition for facing. A more convenient metal profile for drywall is not found. The whole secret lies in the dimensions of the wall of the PS profile, which provides complete docking without gaps or deformation.
The shelf profile of the rack is 48.5 mm, so for the installer of frame-skinned structures, the work is simplified to a minimum. When installing screws for fastening "getting past" the profile shelf is excluded. Especially it is nice when the two-layer planking is joined.
The rack profile has the following dimensions:
PS 50h50
PS 65h50
PS 75h50
PS 100x50.
The price of the metal profile is available.
Installation of drywall sheets is unidirectional starting from the open part of the rack profile. When fastening on the profile of subsequent sheets, the screw to be installed does not bend around the shelf, and the longitudinal grooves impart particular strength. The rack profile is mounted together with a guide profile, suitable for the size. Choose this type of profile is necessary based on the installation height of the wall and its design features. Fixing the profile PS is carried out with the help of screws and screws, using a cutter, using the method of cutting.

profile guide PN
The zinc-plated guide profile is intended for the construction of rigid bridges between the rack profile. It is universally used for installation of framed gypsum board structures for facing walls and ceilings.
Therefore, the installation of the guide profile is carried out in conjunction with the rack profile. The recommended step of mounting the guide profile is 30-50 cm.
The profile of the guide has the following dimensions:
Mon 50x40
ПН 75х40
ПН 100х40.
Fastening of the profile of the guide is carried out to the bearing structure using special suspensions. Direct mounting fasteners fasten to the profile with screws and screws, as well as special connectors.
ceiling profile PP
Ceiling profile is galvanized for the construction of a framework of ceilings suspended, as well as facing the walls. A distinctive feature of the ceiling profile is the presence of three grooves on the shelf and back of the profile to center the fastener.
Fastening of the ceiling profile to the structure of the carrier is carried out using suspensions. Special suspensions are equipped with a clamp. Mounting using a suspension with a clamp gives the design additional reliability, and serves as a stop.
The ceiling profile has a single section size:
PP 60h27.
A sufficiently wide wall of the profile allows for the installation of a frame-shell construction with minimal time costs.
Fastening of the ceiling profile is carried out in the traditional way.
How to use metal profiles when installing your own hands the ceiling from gypsum board is presented in the video.
angular PU profile
The main purpose of the angular profile is to protect the outer corners of the partitions of structures and lining from undesirable mechanical action. Angular profile has a characteristic section in the form of an acute angle of 85 degrees. The tight fit of the flanges of the angular profile ensures the necessary fit of the lining to the surface of the shell construction.
metal square profile
In addition to well-known metal profiles, special attention is paid to the profile pipe of rectangular cross-section. A rectangular profile tube or a metal square profile is a hollow article having a strictly regulated cross-sectional shape and a standard length.
The metal square profile has certain physicochemical properties that make it possible to use this type of profile everywhere.
An obvious advantage of the square profile can be called the ability to interact with symmetrical working surfaces. Therefore, the scope of application, except for the use of pipes as support legs for the kitchen table, is quite diverse.
Thus, the role and significance of the metal profile during the erection of skeleton-like structures has been confirmed by practice.
