Historical Development of Rollform Technology
The origins of rollform machines date back to the 18th century, when metalworking technologies accelerated during the Industrial Revolution. Initially, metals were shaped by hand, but later, this process became automated with steam-powered machines. In the 20th century, with the rise of modern industrial needs, rollforming technology became more sophisticated, revolutionizing production processes.
In the 1960s, the emergence of computer-aided design (CAD) systems optimized the design and manufacturing processes of rollform machines. The machines developed during this period became equipment capable of operating with higher precision and efficiency.
Today, rollform machines (working on the principles of Rollform Machines Working Principles) are supported by intelligent automation systems, sensor technologies, and integrated software. Particularly in the light steel structure sector, these machines ensure that construction projects are completed quickly, economically, and in an environmentally friendly manner.
Working Principles of Rollform Machines and Technical Details
Rollform machines are specialized equipment that transform metal sheets into desired profiles by passing them through a series of molds and rollers. These machines ensure that the sheet is shaped precisely and that production can be adapted for different construction projects.
1. Raw Material Selection and Feeding Process
The working process of rollform machines begins with the selection of raw material, the foundation of production. The quality of the metal sheet used directly affects the durability and performance of the final product. Galvanized steel is typically used in light steel structure projects. Galvanized steel stands out for its corrosion resistance, long lifespan, and economic cost. Due to its high resistance to harsh environmental conditions, it is indispensable in the construction sector.
The raw material is typically fed into the machine in coil form. This coil is automatically aligned and fed into the machine via special transport systems. Proper alignment of the sheet is critical for the smooth progress of the production process. At this stage, advanced sensors and alignment systems on the machine continuously track the sheet’s position along a single axis (+y / -y or +x / -x) with the help of encoders. If the sheet experiences slippage or jamming, the systems issue automatic warnings to prevent errors.
In some advanced rollform machines, the thickness and surface quality of the sheet are also monitored by sensors. This prevents issues related to material quality during production. The raw material control and feeding process form the foundation of production efficiency and final product quality.
2. Shaping Process
After the raw material is fed into the machine, it moves to the shaping process. In this phase, the sheet material is passed through a series of sequential rollers, each of which creates a specific shape change on the sheet. One of the most important features of rollform machines is that this shaping process occurs in a continuous motion, preventing time loss and ensuring that the production process proceeds without interruption.
The rollers used in the shaping phase allow the sheet material to gradually form into the desired profile. For example, C, U, or Z profiles produced with the working principles of Rollform Machines are created during this phase. Each roller set focuses on a different section of the sheet, ensuring that the deformation is distributed evenly.
Flower Opening Design:
One of the most critical aspects of rollforming engineering and the working principles of rollform machines is the flower opening design, which allows precise planning of the shaping process. Flower opening is a design process that graphically represents which shape change the sheet will undergo at each roller set. This method ensures that stress and deformation on the sheet are evenly distributed.
For example, in the production of a C profile, the bending degrees of the sheet’s edges, the flatness of the center, and the angles at the corner points are carefully calculated. This design prevents tearing, cracking, or loss of strength in the sheet. At the same time, it minimizes material waste, reducing production costs.
In modern rollform machines, the flower opening process is typically carried out by specialized software. These programs enable engineers to quickly and accurately plan complex designs. This technological approach speeds up the design phase and ensures high precision during production.
3. Punching and Cutting Process
After the shaping process is completed, the profiles move to the punching and cutting stages. In this phase, holes are drilled in the profiles to facilitate their connection during assembly, and they are cut to the desired lengths. The precision of the punching and cutting process is crucial for the alignment and durability of light steel structures during assembly.
Punching is typically done with hardened steel blades, ensuring high accuracy. The cutting process allows the sheet to retain its shape while minimizing deformation. Some rollform machines are equipped with automated systems that pre-program the punching process. This speeds up the production process and prevents human errors.
During the cutting phase, the profiles are cut to specific standard lengths or project-specific measurements. The working principles of Rollform Machines ensure that hydraulic cutting systems carry out the cutting process smoothly and quickly. Additionally, precision measurement systems on the machines ensure that each cut matches the desired measurements exactly.
4. Exit and Quality Control
The profiles exiting the rollform machines undergo a comprehensive quality control process at the final stage of production. This process involves checking the dimensional accuracy, surface quality, and accuracy of connection points. Quality control is a vital step to prevent defective products from being used in projects.
In some advanced systems, quality control results are automatically recorded, and this data is used to analyze the overall performance of the production process. This not only improves the current production process but also helps prevent potential issues in future projects.
Once the quality control process is complete, the profiles are prepared for shipment or assembly. The working principles of Rollform Machines ensure that profiles are packaged specifically for projects and stored in a way that prevents damage during transport, or the profiles are assembled to create steel panels for structures. This process is carefully followed to meet both the manufacturer’s and the client’s expectations.

Technological Innovations in Rollform Machines
The rapid advancement of rollforming technology, based on the operating principles of rollform machines, has led to a significant transformation in the industry. Next-generation machines offer higher efficiency, reduced energy consumption, less waste, and better quality, making a significant contribution to the construction sector. Among the key innovations are smart sensors, the SABS system, hybrid production systems, and advanced cutting technologies. Each of these innovations is designed to optimize production processes, enabling faster and error-free production.
1. Smart Sensors
Smart sensors integrated into rollform machines are one of the most important technological innovations used to monitor machine performance and automatically detect and correct potential errors. These sensors collect continuous data at each stage of the machine’s operation, which is then used to make the production process more efficient.
These sensors play a critical role in stages such as raw material feeding, forming, printing, punching, and cutting. For example, during the shaping of the sheet, the sensors check whether the sheet is positioned correctly, preventing misalignments. Additionally, parameters such as sheet thickness, hardness, and surface quality can be continuously monitored by the sensors. This early detection of any errors or deviations allows for corrective measures to be taken, reducing waste, speeding up production, and improving quality.
In addition, some smart sensors monitor the machine’s energy consumption and can automatically adjust the system’s operating speed to prevent unnecessary energy waste. This is particularly important for ensuring energy efficiency.
2. SSABS System (Sheet Anti-Blockage System – UNBAK Patented)
The SABS (Sheet Anti-Blockage System) has been a revolutionary innovation in light steel structure machines developed by leading manufacturers like UNBAK Machinery. This system prevents sheet material from jamming inside the machine, ensuring that the production process continues without interruptions.
One of the common issues in light steel structure machines is the accordion-like jamming of the sheet. This usually occurs when the material is not properly guided or when the machine’s processing speed is incorrectly set. In rollforming machines that use the rollforming principles, such blockages cause significant disruptions and time losses in the production process. However, the SABS system prevents this problem by monitoring the passage of the sheet through the machine and automatically intervening to prevent any blockages. As a result, the production process continues smoothly without any issues.
The major advantage of this system is its automatic intervention mechanism. It doesn’t require continuous operator intervention during production, which saves time and allows the machines to operate more efficiently.
3. Hybrid Production Systems
Next-generation rollform machines are equipped with hybrid production systems to make production processes more efficient. Hybrid systems are dual-function machines capable of performing both cutting and punching simultaneously. These systems allow machines to occupy less space and perform tasks more quickly.
Performing punching and cutting processes in parallel significantly increases production speed and eliminates time losses. These systems are particularly useful when there are time constraints in projects. Additionally, hybrid systems provide flexibility by being able to perform the same operation on different types of profiles. Thus, high efficiency is achieved in the production of various materials and profiles.
Robotic arms and automation systems used in modern hybrid production systems ensure that these operations are carried out quickly and accurately. Moreover, the synchronization between machines ensures that the entire production process is seamlessly connected. This prevents loss and errors during the production process.
