Metal frame – what is a shed? Types and use of sheds
rose roofing: Sole refers to metal structures with a sloping roof that are designed and produced in different types and shapes based on technical calculations. These inclined structures have different dimensions according to the type of application. Sules are used to cover large openings and in industrial and agricultural buildings such as factories, warehouses, airplane hangars, repair shops, sports halls, parking lots, chicken farms, livestock farms, stores and other cases. . The important thing about these structures is the affordable and appropriate price of the shed, which should be very careful regarding the type of application and dimensions. Parts with variable dimensions are often used for the construction of industrial sheds and industrial halls, and the weight and dimensions of these parts change according to the type of use of each industrial unit, and the most important factors affecting the final weight and tonnage of industrial sheds are the location The desired place for their construction in terms of wind speed, the maximum amount of snow, the height of the columns, the opening of the hall and, if necessary, the construction of a roof crane.
Installation of rafters, they must be kept firmly in the place of installation. With the correct placement of the purlins, two purlins or lape are placed between the rafters of the roof.
Effective factors in the final weight of shed construction
In other words, a shed is a prefabricated steel structure that has been used the most all over the world and is used in more than 90% of warehouses, stadiums, industries, factory production halls, etc. The shed is changed in various forms based on the dimensions of the opening, height, length and snow load tolerance and the wind speed of the area at the time of design.
The most important principle in order to make every order economical is to know the actual amount of the mentioned dimensions and predict the required items. It is very clear that the best design calculations of shed members without the need to observe the quality of welding, rust removal and scientific painting or the correct operation of components, the use of bolts and other standard connections, will lack the necessary efficiency and strength.
Design and construction of industrial shed
Components used in the metal shed frame
In general, the components used in shed construction can be divided into the following:
Column: Columns are one of the most important components of the columns, which are often made of sheet beams. The task of the columns is to bear the weight of the shed and resist critical conditions such as earthquakes.
Wall post column: Wall posts are sub-columns that support the wall, which are installed at the beginning and end of the structure and transmit and restrain the wind force.
Struts: Struts are responsible for connecting the frames of the slab to each other and resist longitudinal pressure.
Canopy: This structure is a sloping roof.
Angle bra: these components transfer the forces and loads that enter the structure to the poles.
Windscreen: There are two types of windscreen in sheds. Body brace that transmits wind force to the base and roof brace that transmits wind force through the frame.
Segrad (retaining bar): These bars are installed on the roof and transfer the incoming forces to the middle of the sheds.
Rafter (frame): Rafters transfer the load to the sheds to the columns.
Purlin: Purlins also have the task of transferring loads to the column.
Bolts and nuts: The structural components of the beams are connected to each other through bolts and nuts.

Types of sule based on shape
In this section, we describe the types of sheds that are divided based on their shape:
Arched sheds
Sheds with common columns
Sheds with common middle columns
Multi-span sheds with columns
Single slope sheds
Single slope sheds with central column
Single slope sheds with middle columns
Single slope sheds connected to the building
The construction process of the industrial shed structure
Types of sheds in terms of the location of the opening
In this section, we describe the types of stacking in terms of opening placement:
Single opening sheds in the form of 88
Sheds with two or more openings with a common column in the form of 88 or 888 or 8888
Sheds with two openings in the form of 8
Arched sheds
Polygonal sheds
Shed factory
Types of industrial sheds based on weight
In this section, we discuss the types of industrial waste in terms of weight:
1) Light shed
Light beams are often used in industrial structures, which are usually two-dimensional and three-dimensional trusses. Light-weight shoes are more versatile than heavy-duty ones and can usually be used anywhere. This type of structure is usually used in cold stores and industrial cattle farms. Light sheds are also called truss style sheds. Since these structures are designed with new engineering methods, they are made of square profile (ST37) and have high endurance. In this structure, the consumption of steel metal is reduced and therefore it has a lower price.
2) Heavy shed
Heavy sheds are divided into two categories, concrete and metal, and the execution time of metal sheds is faster than concrete. Because in the concrete type, it takes about a few days to prepare the concrete. But in its metal type, after the foundation of the structure is prepared, columns and roof rafters can be mounted on the foundation. But in terms of price, the metal shed is more expensive because it is made of steel, which is more expensive than concrete in the current market of Iran. For this reason, most people go for a concrete shed, which uses sheet beam pieces for high resistance to increase endurance.
The difference between light and heavy shed
The differences between light and heavy
The light shed is made of pipe profiles and therefore their weight is less than other methods. It is not low against heavy shed resistance. Of course Sue
