Roll forming is a metal forming process in which metal is shaped by a series of rollers. Roll formers can create shapes out of aluminum, steel, brass, zinc, zirconium and most other metals. Roll forming produces some of the most widely used metal products in existence.
Examples of Roll Forming products include angle irons, aluminum angles and steel angles which are used in carpentry and building applications. Metal trim and metal channels are also widely used in construction, but they are also used in the manufacture of industrial, commercial and consumer products. Metal rings are used to embellish buttons on telephones, in elevators and even clothing. They also prevent hoses from disconnecting, street signs from falling and they secure lock hardware in doors. Metal wall panels can improve the appearance of a wall in an office, or it can protect a wall in a factory from flying debris or sparks. All of these roll formed products are produced in stock quantities by metal fabricators because of the constant, high demand for them. However, in the many cases in which a stock roll formed product is not appropriate, custom roll forming provides specialized products in large quantities and of uniform quality. Roll forming is a modular process; roll formers can be configured to produce all manner of metal shapes.
Roll formed parts boast a variety of advantages over alternative forming processes; roll formers generate very little scrap material while simultaneously improving the qualities of strength and durability in the metals they process; this makes them very cost-effective compared to other metal shaping processes. Roll forming is a cold forming process, which means that no heat is used to make the metals pliable. Instead, compression and force are used to shape the metals; the compressive stress created by the rollers imparts qualities of strength as they shape the metal. Other metal shaping processes like thermoforming can create larger amounts of scrap, they can be more energy intensive and the machinery can be expensive. Also, roll forming is a continuous process, which means that as long as a roll former is fed with a continuing supply of metal, it can continue producing shaped products. The only major drawback to roll forming as a metal shaping method is the labor intensity of roller configuration; this process requires a trained professional to precisely set roller systems to ensure a flawless finished product. Recent advances in computer control systems have made this process easier, but it can still be costly.
Roll formers work by forcing metal through a series of rollers. At the beginning of a roll forming process, a stock of metal (which is usually coiled to allow for easy access by the machine) is fed into the first set of rollers. The first sets of rollers in every roll former are designed in advance to fit tightly around the contours of the metal stock. Each subsequent set of rollers is slightly different in terms of position, allowing for the gradual shaping of the metal as it passes through the rollers. For example, if a customer orders circular metal clamps, a roll forming company takes a stock of metal strip that looks like this: ---. That strip is fed into a roller system that creates circular metal clamps. The first set of rollers may look like this :::: with the metal strip gripped horizontally in the middle. Slowly, the position of each successive roller in the system would change so that the metal strip, whose horizontal cross section originally looked like a straight line, changes until it looks like this: ?. One drawback of roll forming is that it cannot create sealed ring products; a roll formed metal ring must always be welded or connected with fasteners in order to become sealed.
Roll forming services can quickly and efficiently accommodate high-volume orders. Because roll forming is continuous, high-volume roll form production is often very cost-effective. However, roll former configurations vary in terms of output speed; a given roll former can produce anywhere between 30 and 600 feet of roll formed metal products per minute. Most roll formers are capable of using near 94% of stock metal material during forming operations, which minimizes waste, maximizes efficiency and boosts profitability. Roll forming operations that involve punching or other surface area reduction services produce more waste than those that don't provide such services. Roll forming is an excellent choice for the shaping of coated, finished, cured or otherwise treated metals. Because roll forming processes don't involve heat, and because rollers can be coated with powders or oils that don't react with the metals that they shape, roll forming can shape metals without affecting surface properties. This makes it an ideal shaping method for polished metals, coated metals and other metals whose aesthetic properties must be maintained.

Roll formed parts are made from metal strips. The metal strips are formed using roller dies of a desired size and shape. The process of making roll formed parts is called roll forming. The technique allows a metal fabrication business to create continuous metal strips. A variety of shapes can be formed using different materials, including metals (both ferrous and non-ferrous) and alloys, with the help of roll former machines.
The roll formed parts are used in a large number of industrial machines and in utilities that we use in our everyday life. These parts can have assorted shapes, different angles, and curves depending on the requirement of the client.
The metal forming process offers many advantages some of which are:
Robust and Efficient
As said earlier, roll formed products are made from metal and alloys. Undeniably, metals and alloys add strength to a part. The products are made with long metal strips, usually carved from a coil. However, the process does not take much time to complete, but it brings the resilient characteristics of the metal to the component.
With roll forming process, you can complete a complex design within few hours. Forming of rolls begins with long strips of a metal coil. The coil is sourced in the desired cut. Only the design conceptualization and implementation have to be done by the product manufacturer. That is why the metal roll forming process does not take much time to complete.
Low Production Cost
The coils are sourced from some other manufacturer. No time and labor are needed to create metal strips. As a result, the roll forming process with pre-cut metal strips helps the roll forming plant keep their production cost low.
In addition to this, the roll forming process does not involve heat to roll the metal strips. It helps save on energy or fuel costs. Other methods of metal part production need some kind of heat source to bend the metal strip. However, the roll forming technique does not have such requirements.
Further, identical parts are created using the strips of the same size, meaning there are fewer chances of material wastage. This is another kind of saving.
Higher Production Volume in Less Time
The use of metal strips allows a manufacturing business to achieve higher production level in comparatively less time. With this method, highly accurate and efficient constant-profile parts can be created in large quantities.
Roll forming is a powerful yet flexible method. Many complex designs that are impossible to form via cross section cutting or stamping method can be easily created through roll forming method. Creating C channels, J channels, U channels, metal rings, and many other metal trims is possible with this method.
Any metal - whether ferrous or nonferrous -can be rolled and formed with the roll forming method. Another benefit is you can work on and roll form a pre-finished part that already has layers of painting, coating, and plating.
Roll forming is the process of bending a metallic sheet to produce angular or rounded shape or frame used in a variety of industries all over the world. It is a popular metal shaping process for the production of roll formed parts that conform to the desired shape, precision, and tight tolerance of the components. Roll forming can shape many different types of metals like steel, aluminum, tin, brass, and zinc, providing the desired shape per specific customer requirements.
Whether you require custom fabrication of stainless steel sheets or metal wall panels, you can easily check out a prominent and certified manufacturer and get the desired components manufactured at a competitive price. Roll forming companies fulfill requirements of a diverse set of industries that include automobiles, fences, and metal buildings and even houses.
A customized roll metal products manufacturer can help you if you need metal channels like C-channel frames, car frames, fence posts, angled posts, wall panels, stabilizers, and railings. Roll forming lines can be set up into two distinct process types; namely, pre-cut roll forming and post-cut roll forming. In pre-cut roll forming, materials are cut to length before entering the rolling machine; while in a post-cut roll forming, profiles are cut after the roll forming process.
Besides roll forming, many manufacturers provide other kinds of rolling services that include roll bending, profile rolling, controlled rolling, ring rolling, and hot rolling. When you utilize roll forming services from a top-notch metal forming company, you are most likely to get the following benefits-
Roll forming provides you the flexibility to get the metal sheet design changed during the rolling process by making little adjustments either manually or through a computerized process. You can either get material of different size and thickness using the same roll or get the desired holes, grooves, or a design stamped on the rolled metal. Besides this, the innovative technology of cold compression adds strength and durability to the metal.
Being less labor and energy intensive and more a continuous process than other metal shaping works, roll forming provides a steady production of materials, thereby lowering the cost of manufacturing per piece. This will fulfill your low volume or bulk industrial requirements and will boost your production and profits.
A roll former, depending on its type and configuration, can cut 30-600 feet of metal sheet per minute. As a roll former uses 94 percent of the materials fed into it; therefore, it produces the least amount of scrap materials. This makes it eco-friendly and the most suitable choice for shaping various kinds of metals.
Roll forming does not involve heat and rollers do not affect the surface properties of the metals. These features make it an ideal choice for shaping polished metals, coated metals, and other metals whose beauty and aesthetic properties need to be maintained.
Roll formed parts or products are made using the roll forming technique. Roll forming is a method of creating shapes having continuous designs and patterns. It is an ideal technique for making metal components and parts with a consistent design or pattern running across the length and width of the part. Metal sheets or metal coils are used to create roll formed parts.
Roll forming manufacturers have horizontal series of rotating dies. These dies help them produce a uniform and constant cross-section profile.
Each of the dies brings incremental and desired changes in the long metal strip to turn it into the desired shape. After the designs have been formed, the curved part is then cut according to the required length.
Roll forming is an economical method of metal part designing and manufacturing. Other techniques like stamping and die casting are more expensive because of material wastage and the requirement of other processes. The roll forming method uses metal strips that are sourced in already cut condition. Roll forming process only is performed in the strips.
The biggest benefit of roll forming is it eliminates the need for other processes such as stamping, die casting, piercing, notching, and deburring. The strips used in this method of parts manufacturing are already supplied after performing these steps. Since these processes are completed before, the production time and cost remain low. Additionally, the parts created are of high quality.
Roll forming is a versatile metal fabrication technique. With this method, you can work on a large number of metals and alloys. Typically, steel is the most frequently used material for roll forming. Some of the most commonly used roll-formed materials are galvanized steel, stainless steel, carbon steel, brass, copper, zinc, titanium, etc. Additionally, already finished parts can also be designed and roll formed.
Customization options are also available for roll forming. You can get roll formed parts in your desired material, design, shape, and size. However, you will have to check the availability of this option with your manufacturer or supplier.
A number of shapes can be easily designed and roll formed. However, there is no denying the fact that not every conceptualized shape can be formed with this technique. Sometimes, a pattern may look simple, but it may not be the ideal choice for roll forming. However, you can speak to an experienced manufacturer regarding your design; they might be able to provide you with a possible solution.
Creating customized roll formed parts takes a creative brain. A design or pattern has to be created that can fit into the exact client specifications. Before bulk production, the suitability of the part should be tested.
Choosing to customize your order of roll formed parts gives you pre-finished components that will come to you in precut condition. The supplier gives you parts that are ready for assembling. You will just have to begin with the production of your product or application using the custom roll formed parts.
In short, roller forming is a perfect method for producing constant-profile parts with long lengths and in large amounts.
Roll forming is the simplest metal shaping process that produces metal parts of desired cross section with the highest degree of precision and uniformity. This is done by passing a long sheet of metal through a horizontal series of rollers to get uniform rolls of the metal. The roll formed parts are then cut to the specified length of the final part.
It is one of the quickest ways to create complex metal shapes, usually of steel, brass, zinc, aluminum, zirconium, and other metals. The rolled metal parts are used in a diverse set of industries, including automotive, retail fixtures, and home and office appliance industries. Be it the production of metal rings, aluminum angles, steel angles, and steel channels, manufacturers use roll forming to produce these parts in bulk.
What makes roll forming more beneficial than other metal shaping processes is its ability to produce parts of great strength and durability in large quantities, saving money and time. The process also produces very little scrap materials.

Consider their turnaround time and delivery options to streamline your production process.
Roll forming companies have known for many years the many benefits of using the process of roll forming to create complicated and complex metal shapes. Roll forming is often used to manufacture large metal pieces, and it has many benefits over other forms of metal shaping such as pressbreaking. If you are interested in using roll formed metals, consider some of the following advantages:
Lower costs: Roll forming requires less material handling and labor. This creates a continuous production and lowers the cost-per-piece of each metal piece.
Increased consistency: For large orders, roll forming creates pieces that are identical every time. You will find more accuracy, uniformity, and consistency in individual pieces as well as the entire production lot.
Fewer secondary operations: With roll forming, you can add additional extras, often saved for secondary processing, at the same time. During roll forming you can cut, notch, perforate, punch, and otherwise change the metal during the initial production. This also increases the structural integrity of the piece and better parts joining.
Rapid delivery and turnaround times: Because roll forming is done mostly with one simple process, parts can get to your sooner. Basically, roll forming is a one-stop shop that allows your metal parts to get to you sooner with greater accuracy and cost savings.
For these reasons and more, if a company has the option of choosing to use roll formed metal, you will not be sorry. Roll formed metal is highly effective and beneficial in a multitude of ways.
