What Is a Metal Roll Former?

A metal roll former is a machine that uses a continuous process to turn steel coils into engineered shapes. Unlike traditional stamping, it can produce complex profiles without changing the material’s shape too much.

To keep a roll former running well, it is important to maintain a regular lubrication schedule. This metal roll former will help prevent the machine from overheating or breaking down.


With a metal roll former, metal strips can be cut to precise lengths and shaped into complex shapes. The machine’s roller sets gradually shape the strip into the desired cross-section. This process is much faster than traditional manufacturing methods and is cost-effective. It also eliminates the need to heat and cool the metal. In addition, the system can add a variety of features to the end profile such as notching, holes, and tabs.

Metal roll forming lines usually start with equipment that prepares the coil metal for the process. This includes a decoiler that keeps the coil and feeds it into the line. It can be floor or pit mounted and can have a number of different capacities depending on the size of the coil. The coil may also need to be flattened and trimmed in order to remove coil set, which is the tendency of the coil to stay tightly wound.

Depending on the production needs, some companies prefer to use pre-cut lines that shear the sheet metal before it enters the roll former. This can be a good choice if the line produces a lot of length-specific parts. It can also save money by eliminating the need to change the cutoff dies. The B&K Super Mill shears can be used to produce a variety of sizes, from drywall to structural framing. Its patented design is highly accurate and offers powered fine adjustments to minimize flaring, making it the ideal choice for steel framing applications.


A metal roll former is a machine that can shape steel into complex, long-length profiles. It can also perform secondary operations, such as punching and welding, on the same line. These machines are ideal for manufacturing large-scale components, such as automotive parts and roofing. They produce high-quality products at an affordable price and reduce the time and cost of labor.

Metal roll forming is an ancient process that began in 6,000BC and involves hammering flat pieces of metal into a desired shape. In the modern world, this technique is used to create a variety of products for use in cars, airplanes, homes, and even skyscrapers. It is one of the fastest and most economical ways to produce a product, saving time and money by eliminating additional finishing steps. A cold-rolled steel profile requires minimal finishing work, and is more durable than its hot counterpart.

Some manufacturers choose to pre-cut the sheet before running it through a roll former, while others prefer to cut the blanks after the machine has finished forming them. Both methods have their pros and cons, and the choice depends on the shop’s production requirements. For example, a pre-cut system eliminates the need for a shear, reducing maintenance costs and downtime. However, a pre-cut system can require more forming stations than a post-cut one, which can affect the quality of the finished product.

End shear welder

Metal roll forming is a process of continuously bending a strip of metal into a desired shape. This method of manufacturing is highly efficient and cost-effective, making it a great option for producing large numbers of parts. Metal roll forming machines are capable steel frame roll forming machine of creating complex shapes from metal coils. However, it is important to understand the differences between different types of metal roll forming lines before making your purchase.

To help increase productivity and accuracy, metal roll forming equipment is often equipped with an end shear welder. This feature allows the operator to connect the tail of one coil to the lead of a new coil without having to manually feed or rethread the machine. This helps reduce the amount of time it takes to get the line back up and running after a coil change, saving fabricators money and time.

It can also be used to monitor the quality of welded joints and cut edges. This inspection system can track the position of each part as it moves through the machine, ensuring that it is in the correct position for the next process. It can also check for quality control issues such as dimensional accuracy and number of punched holes. These systems are available from a variety of vendors. They can be configured to monitor the entire line or just certain segments.

Pre-cut shears

A pre-cut shear is a convenient addition to a metal roll former line. It is designed to cut a flat pattern, allowing for features such as notching or punching holes and tabs to be integrated into the end profile of a panel. It also allows for a faster cutting process, since it is not necessary to stop and cut the sheet into lengths. Modern shears also feature a length measurement system, which makes it easy to maintain consistent panel dimensions.

This type of shear can be close-coupled to a panel rollformer, reducing floor space needed to operate the machine. Its dual acceleration arms and stable, heavy-duty linear bearings give it the precision and speed required for optimal shear performance. Its four-roll cluster of work rolls eliminates upbow and down bow in the strip, ensuring that the shear blade is always in the correct position to cut. It also features a two-blade reversible design, which can save on maintenance costs and reduce the need for lubrication.

A pre-cut shear is a good choice for lines that run multiple profiles, such as Cee or Zee purlin and double-high rafted line. In addition, it can be used to create short panels for soffit or wainscot, as well as long panels for press-formed ridge caps. Pre-cut shears can also help minimize end flare. These are often difficult to control on a post-cut line. A pre-cut shear can minimize this problem with the use of anti-flare fixtures, which are servo-controlled and can be adjusted on the fly.
