All kinds of metal profiles, which are long products with different cross-sectional shapes, are produced by rolling the sheet.
Product Advantages
- Strength.
- Easy.
- Economy.
- High speed editing.
- Long service life.
These properties of profiles make it possible to use them in the construction of buildings and in their decoration of various levels of complexity. In this case, a force calculation of load-bearing structures is required.
Types of deformation of metal profiles from the load - elastic and plastic. The latter is irreversible and should not be allowed as it leads to structural failure.
Metal profile: types
Depending on the purpose, profiles come in different shapes and manufacturing methods. They are necessarily protected from corrosion with zinc and other coatings.
1. Profile pipe
The profile is a hollow product with a cross-sectional shape in the form of a square, rectangle, oval, polygon. It is intended for outdoor construction and finishing works. Various metal structures, doorways, floor beams, rafters are erected from it.
The profile is an analogue of a wooden or reinforced concrete beam. It is produced by cold or hot deformation of sheet metal. The complexity of manufacturing significantly depends on the size and thickness of the walls. Welding is mainly used, but there are also seamless products obtained by deformation of a round pipe.
Steel of different grades and aluminum alloys are used as profile material. The width of products is 10-180mm and the wall thickness is 1-12mm.
Types of metal profiles are diverse, but products of square and rectangular sections have the highest bending strength. Compared to hot-rolled section steel, 20% less is consumed. At the same time, the surface area in contact with the atmosphere is 40% less. This means less corrosion protection is needed.
Installation of profiles is carried out by electric welding, but you can use clamps and other fasteners. Steel structures are lightweight and highly durable.
In everyday life, profiles of small sizes and simple shapes are used, and in industry - a wide variety of types of metal profile (photo below).
Profile pipe made of steel is usedin the construction of pavilions, stalls, sports grounds, supports for various purposes, billboards.
Minimum dimensions are suitable for the production of furniture, sports equipment, interior decoration. Profiles with a section of 100x100x6 mm and above are used as load-bearing structures of private houses.
Aluminum products are used when it is necessary to create structures with low weight, ductility and high corrosion resistance. Their transverse dimensions do not exceed 80 mm, and the corners can be rounded or straight. To increase strength and ductility, aluminum alloys are created with the addition of manganese, copper and magnesium.
2. Drywall profiles
Profiles are used to create building and finishing structures indoors. They are distinguished by cross-sectional shapes and sizes. Partitions, suspended ceilings are made of them, and they are also used for wall cladding. Mostly use a metal profile for drywall, the types of which are as follows:
- rack-mounted (PS);
- guide (PN);
- ceiling (PP);
- angular (PU);
- bent (PG).
PS is a strip bent from tin in the form of a channel. It is easily deformed during the production of profiles and can be made manually using simple machines. For rigidity there are longitudinal corrugations.
PS is designed for the manufacture of vertical posts, partitions or wall cladding. It is mounted in tandem with a suitable guide profile size. Themforms provide for tight docking with each other. The holes in the walls of the substation are designed for wiring.
PN serves as horizontal U-shaped rails into which vertical posts are inserted. It also serves as a guide for the appropriate size PCBs.
PP is used for wall cladding and false ceiling framing. It is attached to the base with suspensions. It is convenient to purchase false ceiling profiles complete with connectors. Then its installation is easy and fast.
The corner profile protects the outer corners of the plasterboard sheathing from damage. The sharp angle of the cross section allows the profile to fit snugly against the cladding. It is perforated so that the putty penetrates through the holes and firmly holds the metal to the skin.
PG is convex or concave and can be with different radii of curvature. It serves to create arches and multi-level ceilings.
3. Accessories
All types of metal drywall profiles are fixed with the following accessories.
- Two-level profile connector when they intersect each other. It is shipped unrolled and needs to be bent into a "U" shape before installation. Fixation is made with self-tapping screws, which are screwed into the perforation.
- Single-level connector "crab" is designed to fasten profiles when they cross crosswise. It snaps onto the profiles and is still fixed with self-tapping screws under high loads.
- Direct suspension serves forfastening racks to walls, as well as when mounting the ceiling.
- Profile extension is used when it needs to be extended.
Gypsum boards are attached to the profiles with metal screws. Together with a press washer, they are suitable for all kinds of connections. Their tips are made piercing or drilling. The frame is attached to the walls with self-tapping screws with plastic dowels, and the suspension to the ceiling is fixed with an anchor wedge or a ceiling dowel.
Types of metal roof profile
The truss system of the house is made of steel in order to reduce loads, increase service life and fire safety.
Types of metal profiles for load-bearing structures include bent and hot-rolled, but the latter have more weight and consumption (channel, beam, angle). The crate is also made of steel. At the same time, the entire metal is protected from corrosion by zinc or other anti-corrosion coating.
The advantages of metal structures
- Profiled steel is a strong and lightweight material.
- Fire safety.
- No deformation inherent in wooden structures.
- Compatibility with roofing material: corrugated board and metal tiles.
- No waste during installation.
Features of making a roof from a profile
Roof structure must be pre-calculated for strength. To withstand climatic influences, the coating is securely fastened to the crate, which is a metal profile. Species can bedifferent, but the most common are galvanized steel hat laths.
Their price is higher than that of similar wooden structures. But they can be cheaper than a bar with the same technical characteristics. Sometimes mixed structures made of wood and metal are used. At the same time, you should be aware that condensate on the metal can cause waterlogging and rotting of the wood in contact with it. In addition, metal is a bridge of cold, and the roof must be properly insulated.
Rafters with trusses are attached to the walls with anchor bolts and fixed for a while in a vertical position. Then a hat profile is laid across, and a coating is attached to it.
Thermoprofile
Types of metal profiles include a thermal profile that looks like a regular drywall profile. The only difference is that it has perforations designed to reduce heat loss through cold bridges. The holes are staggered. Cutting the sheet allows you to lengthen the heat flows through the metal, which significantly reduces heat loss, and also improves the vibration and sound insulation characteristics of the material compared to wood of the same size. The external beams of the house are erected from the thermal profile, and the facade is also sheathed for insulation and thermal contours for the roof.
Conclusion
When making metal frames, you need to know the types of metal profiles and their purpose.
Also used for their fasteningvarious additional elements that facilitate installation. You should correctly navigate in all types and sizes of profiles.
