Metal structures are one of the fundamental pillars of industrial and construction projects, as they are extremely heavy-duty and durable. The Metal Structure Manufacturing refers to the process of making strong and functional structural elements from various metals (usually steel, aluminum or other alloys). These types of structures are everywhere around us, from modern skyscrapers to industrial machinery to transport infrastructure. In this article, we present the the process of metal structure manufacturing and the machines used.
What is metal structure fabrication?
Design, manufacture and assembly of structural elements and equipment made of various metal raw materials (e.g. steel, aluminium) for industrial, construction or other uses. The manufacturing process incorporates metalworking technologies such as cutting, bending, welding, and surface treatment to create durable and stable structures.
The process of metal structure production
In the manufacture of metal structures, several technological processes are used to ensure the durability, reliability and functionality of the final product. Below are the most commonly used steps.
Design and engineering
Before production can begin, all metal structures must be designed in detail. During the design, the functional purpose of the given structure, its load-bearing capacity and the properties of the materials used must be taken into account. Modern metal structures are often made using computerized design programs, such as CAD or CAM systems, which allow for accurate and precise modeling.
Material processing
The raw materials of the planned metal structures are processed in different ways, depending on the type of structural element in question. Some of the most common material processing processes include cutting, bending, drilling, turning, cutting and welding of metals. These operations are carried out with the help of the appropriate machines and tools to ensure that the parts are made in the exact size and shape.
Assembly
Once the individual metal parts have been made, the next step is assembly. The components welding, screwing, riveting or combined with other fastening technologies to ensure that the final structure is stable and reliable. Welding, for example, is a commonly used method that ensures that components are connected permanently and strongly.
Surface treatment
Metal structures are often made for long-term use, so proper surface treatment is essential. The Surface treatment Its purpose is to protect against corrosion, protect against mechanical damage, and improve aesthetic appearance. Some of the most common surface treatment procedures include painting, electroplating, powder coating or other corrosion protection techniques.
Quality Control and Testing
As the final step in production, the finished metal structures are thoroughly inspected to ensure their reliability and safety. During quality control, various tests are carried out, such as static or dynamic tests, to ensure that the structures meet the desired technical specifications.
What machines are used in metal structure manufacturing?
Metal structure manufacturing is one of the fundamental branches of industrial production that requires the use of many different machines and technologies. The manufacturing process ranges from the shaping of metals to final assembly, and different machines are required at each step to ensure the desired precision, quality, and efficiency. Below is a description of the machines used in the production of metal structures by specialized enterprises.
Sheet metal cutting machines
One of the very first steps in the production of metal structures is the cutting of the plates, which is carried out with various types of machines. Some of the most common cutting technologies include laser cutting, plasma cutting and scissoring.
Laser Cutting Machine: Laser cutting machines are among the most modern technologies that allow us to make extremely precise cuts. The intensity of the laser light allows you to cut metals of different thicknesses quickly and accurately, while minimizing heat exposure.
Plasma Cutting Machine: A plasma cutter performs cutting using high-temperature ionized gas. It is particularly suitable for cutting thicker metal sheets and provides a cost-effective solution for the industry.
Scissor machines: Among the simpler solutions are mechanical shears, which provide an even cut for smaller thickness sheets.
Bending machines
Bending machines play a key role in shaping metal sheets into the desired shape. Bending is one of the most common forming processes for metal structures, and various machines are used for this.
CNC bending machines: Computer-controlled bending machines perform extremely precise work while also being able to efficiently process large quantities of sheets. Automatic programming also allows for the creation of more complex shapes, reducing the possibility of human error.
Mechanical benders: Conventional mechanical benders have powerful mechanisms that are capable of forming even thick metal sheets. These are usually used on larger production lines.
CNC machines (computer-controlled machines)
CNC machines are one of the most important tools in the manufacture of metal structures, with the help of which various machining operations can be carried out with the highest precision, such as:
Turning: Turning machines can be used to process metals in a circular motion, such as when forming tubes and shafts.
Milling: Milling machines are capable of forming even the most complex geometric shapes with their multi-axis movement, so they find a wide range of applications in the production of precision parts.
Drilling: CNC drilling machines can be used to make highly accurate holes in sheet metal, which is essential for subsequent assembly processes.
Welding machines
Individual elements of metal structures often have to be connected by welding. Welding means the permanent joining of metals, and there are different technological solutions for it, depending on the needs.
MIG/MAG welding machines: Metal Inert Gas (MIG) and Metal Active Gas (MAG) welding are among the most common welding technologies. These machines use shielding gas to ensure the quality of weld seams and can be used in a wide range of applications for joining sheets of different thicknesses.
TIG welding machines: Tungsten Inert Gas (TIG) welding is a highly precise technique that is mostly used for welding thinner metals such as aluminum and stainless steel.
Spot welding machines: Spot welding machines are common in the automotive and other industries for joining sheet metal quickly and efficiently.
Laser welding machines: Laser light is used to deliver concentrated heat energy to the welding area, which melts the metals and thus creates a strong, clean seam.
Injection molding machines
During injection molding, the molten metal is blown into a closed mold and cooled to produce a finished part. Injection molding machines used in industry are especially suitable for the production of cast metal structures, which can be produced in large quantities.
Aluminum injection molding: Machines especially suitable for injection molding of aluminum alloys, which shape castings with extreme precision.
Iron Injection Molding: Iron injection molding is done using various machines, and these types of castings are used in the automotive and mechanical engineering industries, among others.
