price references of hollow section steel types + cheap purchase
The profile or steel hollow section is a construction element with a fixed section and long length that have many different manufacturing processes
The profiles are used in industries and major companies around the world such as construction, car manufacturing, shipbuilding, manufacturing desks, and office furniture
Different types of profiles have different prices depending on the material, including steel, aluminum, etc
In addition, the thickness of the profile is another factor that determines the price of the profile
What is personal data? Profiles are open or closed sections and are divided into different types according to weight, type of application, and type of cross-section
Therefore, all profiles such as steel, aluminum, and steel are part of the profile category
Below we will examine each type of configuration file in detail
Profile type To understand exactly what profiles are and determine exactly what profiles are, we need to categorize them according to criteria
In the following, we will examine the profile types based on application, properties, material, and cross-section type
Types of building profiles A building profile is a building material used for building construction
Hot rolling and cold rolling are important methods for the production of building profiles
In the production of building profiles by hot rolling, ingots are rolled at very high temperatures, and the resulting products are in the form of rods, strips, sheets, tubes, cans, and shields
In the production of cold-rolled profiles, steel sheets are formed by bending
Products produced by cold rolling are used in door frames, columns, ceiling beams, and other matters
In addition, there is another method for producing building profiles, which is a combination of cold rolling and hot rolling, called the composite method
Types of aluminum profiles Aluminum profiles are often used for structural purposes with some by-products
In this regard, we can mention three types of aluminum profiles according to their use: architectural, architectural, and industrial
Architectural aluminum profiles These profiles provide low self-weight, high bending, and good torsional stiffness for structures in solar panel frames and structures
Architectural aluminum profiles This type is used for applications where appearance is important
Architectural aluminum profiles are used to manufacture window and door frames
Industrial aluminum profiles In industry, they are used where the hardness or quality of the surface is not so important, but combining these two properties with other material properties, such as electrical conductivity, provides a wide range of applications in industry
These applications include cable duct systems, radiators, air conditioning systems, cabinets and furniture, etc
Galvanized profiles The manufacture of galvanized profiles is a chemical, electrical or mechanical process in which a protective coating of zinc is added to steel or iron to prevent the steel or iron from rusting
The most common method for producing galvanized profiles is by hot-dip galvanizing, where the steel profile is dipped in a molten bath
Galvanized profiles have advantages, the most important of which are:
Lower costs while preventing corrosion in corrosive and hostile environments
Protection against mechanical damage to the profiles, e
g
wear due to galvanization
Visual inspection without destructive testing
Composite profiles Composite profiles are very suitable for various applications
They are produced by pultrusion, and by choosing the right resin system, fiber type and surface treatment, special properties such as heat resistance and chemical stability can be achieved, and profiles can be produced according to specific application needs
These profiles are produced in various shapes including U, H, I, L, T, C, and Z sections
Among the advantages of these profiles can be mentioned high corrosion resistance, low weight, vibration resistance, high production speed, and low overall costs, as well as the limitation of the shape of the mold, which reduces the diversity of the cross-section of the mold
the production part and the weakness of drilling
One of the disadvantages of this profile
Types of industrial profiles It is a group of profiles with industrial applications used in industries such as car manufacturing and the defense industry
Industrial profiles have the advantages of light weight, high strength, corrosion resistance and good weldability, which makes them widely used in sensitive applications
On the other hand, the impossibility of fine design and the small range of production facilities is one of the disadvantages of the industrial image
Steel profiles Steel profiles are sections of stainless steel or steel that have been rolled, drawn or pressed and have the same cross-section
Among steel profiles can be mentioned angles and bands, which vary according to their cross-section
Chrome in steel creates a hard and uniform surface that prevents rust
Improved rust resistance through the addition of higher percentages of chromium as well as other alloys, which are the most important properties of steel profiles
Aesthetic appearance and heat resistance are other desirable properties of steel profiles
Appearance-based profile types The profiles are divided into two types: open type and closed type, which are introduced separately below
open profile Open profiles are cold steel profiles with a large gap between the two edges of the profile
The opening of the profile, i
e
the distance from one edge to the other and the extent of this distance, distinguish open profiles from closed profiles and welded parts
Open profiles are very efficient for the audience in terms of cost and weight, while also having sufficient and high strength
Types of open configuration files include the following sections:
Z profile
beam
corner
study
rebar
belt
closed profile The closed profiles include pipes, cans, UPVC profiles, etc
There are two main production methods
The extrusion process leads to the production of seamless profiles, during which, by passing the heated part through the hole, it forms the desired profile
The other method is to use a welding process
In this way, the sheet is formed by rolling, and then its tubular edges are welded together
Profile type based on construction method Hot-rolled profiles Profiles made by the hot rolling method experience temperatures above 1700 degrees Fahrenheit, which allows these profiles to form well and reach the desired dimensions
Due to the high temperature, an oxide layer develops on the surface of hot-rolled profiles, which increases the corrosion resistance of these profiles
However, profiles produced by hot rolling have a rough surface due to the presence of this oxide layer
Cold rolled profiles Unlike hot-rolled profiles, cold-rolled profiles produce profiles that have a smooth, polished surface and are stronger
But they have smaller dimensional variations compared to hot-rolled profiles
What are the disadvantages of a profile? Now, after understanding the types of profiles and how to make them, we will examine some of the mentioned disadvantages of profiles
Lightweight profiles or furniture boxes are profiles with a thickness of less than 2 mm
Due to their small thickness, the use of this type of profile is not recommended at all in places that require high resistance and strength and high pressure on metal materials
Galvanized profiles are rust-resistant due to their zinc coating, but are not recommended for use in special weather conditions such as northern Iran, unless a hot-dip galvanized coating is used in their production
Another mentioned profile is the composite profile, which, despite its light weight, has a high brittleness, which is considered its main disadvantage
Z-profile is one of the most used profiles and its service life will be shorter if it is not galvanized
steel hollow section manufacturing
steel hollow sections also known as profiles have different manufacturing processes
In the construction industry, one of the most used building materials is various metal materials
All these products are used in this part of the industry according to their special materials and conditions
In addition, one of the widely used metal materials for various parts of the building is aluminum profiles, which include both architectural and industrial types
The date of the first use of this steel is related to the years after the Second World War
The profile was first used in Germany and was transferred to other European countries after being well received
At the same time, the population in Iran is increasing, and it is important to build new houses that meet international standards
Due to the lack of iron (to learn more about the history of iron, see What is iron) and primary materials, the government approved plans to import iron and came up with the idea of making new and necessary equipment in the country
The first factory to produce profiles on its production line was built by a man named Mansman and his brothers
For the first time, Mansman punched a sheet roll in an inclined shape and made it possible to make different cross sections
After that, profile manufacturing developed and a man named Peiger was able to produce hollow and seamless profiles for special applications
The manufacture of this product continued to progress until after the Second World War, when the welding industry took a great leap forward and opened up new possibilities for production
Even today, the quality of the profiles and the expansion of the production process continue, in order to build more durable structures, many studies and experiments have been carried out on the mechanical and chemical properties of metal profiles, such as wear resistance, abrasion resistance, etc
What is a steel profile? Literally, a profile means that the cross-section is fixed to a certain length
These hollow profiles have been used since ancient times for their extraordinary properties, but you must be wondering what the word means in the construction industry
Profile in Latin refers to equipment used to construct doors, windows, pipes, or building facades
Basically, a profile is a metal structure that is divided into two types in the construction industry, open profiles, and closed profiles
There are different types of open profiles, one of which is a z-profile open profile, and they are used in large buildings
Among their other possible uses can be mentioned the construction of roofs for large halls such as gymnasiums, warehouses, public car parks, and sheds
Open profiles are available in various sizes and thicknesses and are used as consumables for rebars, beams, corners, pins, hashes, four sides, and ties
Closing profiles, these types of profiles are also produced in various sizes for the production of pipes, cans, windows, and doors, PVC profiles, and electric shutter profiles
Types of steel and non-steel profiles
building profiles There are two types of profiles for this type of metal construction, hot-rolled and cold-rolled
The first is a hot-rolled profile, in the form of a can, which is formed by heating a steel ingot
The other is cold-rolled profiles, which are in the form of rivets and are produced by bending a sheet of steel into shape
Of course, these types of profiles are only suitable for light construction work, such as rivets, support beams and sometimes false ceilings and architectural door frames
The third type of profile is the composite profile, which is created by joining together several hot and cold profiles
Industrial profiles Refers to the products used as industrial parts and accessories in various industries such as automobiles and military industries
The attention to mechanical and electrical properties is particularly important at the industrial stage, where technical know-how, work experience and production facilities are placed in a special place so that special parts with specific properties can be produced
Profile producer
There will be no buildings
For prices on various types of construction, industrial profiles, etc
Composite profiles In this new era, a large part of the profile market is composite materials
Composite profiles are very popular in the construction industry, especially in weather conditions with a high potential for corrosion and rust
The main reasons for using this profile are to prevent corrosion processes and increase the life of the structure against atmospheric vibrations
The use of composite profiles makes buildings lighter, but this advantage is not so important
What makes composite profiles durable and long-lasting is their inelastic properties, which make them perform better
Due to the north-south climatic conditions in my country, the use of composite profiles is very extensive
Currently, many structures built in corrosive environments in different parts of the country, such as bridges at Lake Urmia or buildings in the southern part of the country, have corrosion problems, and the use of composite materials can solve the problem of such structures
Galvanized profiles Galvanized profiles are also very useful today as they are used to reinforce UPVC doors and windows
One of the advantages of using galvanized profiles in the construction of uPVC windows is that we do not have problems with tightening and bending of door and window openings
Galvanized profiles One of its other advantages is that it increases its strength and resistance to atmospheric pressure several times at high altitudes, as the wind can put a lot of pressure on the windows high up in the tower
Of course, windows on the lower floors can be loaded due to the setting of the building, you must also be aware that the more loaded the window is, the larger the surface of the window, the galvanized profile must be thickened, usually starting from one millimeter, up to two millimeters depending on the situation
