Products Produced

Common products created through roll forming include angle irons, aluminum and steel angles, metal channels, trims, wall panels, and circular metal rings. Additionally, roll formed items can be tailored for specific uses, such as seat tracks in buses.

In the realms of carpentry and construction, angles are crafted to fortify structures bidirectionally, often equipped with slots or apertures to facilitate connections. In a similar vein, metal channels in these fields offer foundational support to rails and frames, extending their utility to the fabrication of goods across consumer, industrial, and commercial sectors. Metal trim, meanwhile, neatly outlines the contours of parts or products. In industrial and commercial settings, roll formed metal wall panels shield factory interiors from sparks and debris or aesthetically transform the facades of office buildings. Metal rings, those simple loops of metal, fulfill diverse roles—from encasing elevator buttons and enhancing telephone interfaces to decorating apparel, anchoring street signs, securing door locks, and maintaining hose connections.


The origins of rolling technology stretch back to around 600 B.C., with the earliest prototypes of rolling mills unearthed in South Asia and the Middle East. These ancient machines, operating on fundamental principles later illustrated by Da Vinci during the Italian Renaissance, mark the inception of this enduring technology.

Though Da Vinci originally conceptualized rolling machinery, it wasn’t produced during his lifetime. The first actual rolling former, the slitting mill, was introduced in England around 1590, 70 years after his death. In this process, workers inserted flat iron bars into the mill, where they were first shaped into plates and then slit into strips using grooved rolls. Over time, engineers made modifications to the slitting mill, enabling it to also produce roll hoops for barrels.

In the waning years of the 17th century, curious minds turned their attention to the art of rolling tin. In 1697, a British visionary, Major John Hanbury, established a pioneering mill dedicated to shaping “blackplate”—a term for uncoated iron or steel that has undergone annealing. As his ambitions evolved, Hanbury shifted his focus to “tinplate,” a sleek, tin-coated steel. The wave of innovation continued, and in 1759, Thomas Blockley, another British innovator, secured a patent for his method of polishing and rolling metals. A few years later, in 1766, Richard Ford broke new ground with his patent for the world’s first official tandem mill. These tandem mills, designed to roll metal through successive stands, became instrumental in producing hot roll wire rods.

The art of roll forming as it is practiced today traces its origins back to the inventive mind of Henry Cort in the late 18th century. In 1783, Cort secured a patent for a revolutionary method of rolling iron bars using grooved rolls. Although he wasn’t the pioneer of using grooved rolls, his genius lay in integrating this technique with other processes in a novel way. His innovative design dramatically increased productivity, enabling mill workers to produce fifteen times more output per day than previously possible. Thanks to his groundbreaking contributions, Henry Cort is celebrated as the “father of modern rolling.” Cort’s innovation was a pivotal moment in the evolution of roll forming. Following his breakthrough, a wave of engineers and manufacturers emerged, each tweaking and expanding the process to suit their specific needs and the emerging technologies of their times. As technological advancements surged, so did the size of rolling mills and the scale of the products they churned out. A striking example was seen at The Great Exhibition of 1851, where the Consett Iron Company displayed their prowess by showcasing an enormous steel plate that tipped the scales at 1,125 pounds, stretched 20 feet in length, was 3 ½ feet across, and boasted a thickness of 7/16 inches. Merely two years later, the industry made another leap forward as manufacturers started rolling heavy sections with the introduction of “three high” mills.

The landmark strides of the 20th and 21st centuries have largely been driven by the sweeping tide of automation. In the present day, manufacturers of roll formed parts harness the power of CNC technology to meticulously craft their designs digitally before employing the same sophisticated systems to bring them to life. Thanks to this integration of technology, modern roll forming achieves unparalleled precision, complexity, and consistency, propelling the rolling and bending machine market to thriving new heights.

Materials Process

Many metals, whether they contain iron (ferrous) or not (non-ferrous), are suitable for roll forming. Brass, steel, zinc, aluminum, zirconium, titanium, and tin are some of the most frequently shaped metals using this process.


    Brass, a lustrous alloy primarily composed of copper and zinc, is celebrated for its radiant, golden sheen. The myriad forms of brass each display unique measures of its quintessential traits: durability, pliability, luster, resistance to corrosion, and antimicrobial properties.


    Steel reigns as a favorite in the realm of roll forming, cherished for its robust and enduring qualities. It boasts an impressive portfolio: strength that withstands the rigors of use, durability for the long haul, hypoallergenic properties for sensitive applications, resistance to abrasion, and a defiance against corrosion. To meet the diverse demands of its myriad applications, artisans blend an array of steel types and grades, including stainless steel, carbon steel, and galvanized steel, each tailored to specific needs.


    Zinc, a naturally-occurring element, seldom stands alone in nature. This lustrous, bluish-white metal may appear delicate and brittle, yet it possesses moderate conductivity. To harness its potential, manufacturers often blend it with other elements, crafting sturdy and valuable alloys such as brass and bronze.


    Aluminum, a timeless and nonferrous metal, has gracefully woven its story through the centuries, first making its mark as early as the fifth century. Celebrated for its symphony of traits—it conducts electricity with ease, warms and cools with swift precision, molds to the wildest imaginations, stretches without snapping, resists the ravages of rust and flames, repels magnetic advances, and mirrors light with a gleam—it’s no wonder this metal has consistently been a material of choice through the ages.


    Zirconium metal is sourced from the mineral zircon. Known for its impressive resistance to corrosion, it finds its place in specialized uses including light filaments, surgical instruments, and as protective cladding in nuclear reactors.


    Manufacturers often choose titanium when they need to craft parts for heavy-duty applications. This metal stands out for its remarkable strength-to-weight ratio and has a high melting point, impressive ductility, and low density. Additionally, titanium is resistant to both freshwater and saltwater corrosion, withstands high temperatures, and is resilient against fatigue and cracking.


    Tin, a metal frequently mingled in alloys, has partnered with elements like copper for millennia to forge materials of significant utility. In its natural state, tin boasts a soft, pliable nature, resists corrosion from water, and takes on a shine with ease. When combined with other metals, tin’s resilience against both acid and alkali corrosion is notably enhanced.

Process Details

Roll forming transforms the character of metal without the fiery touch of heat. Instead, it employs the relentless embrace of force and compression. As the metal passes through a series of rollers, each exertion crafts it further, instilling the final product with inherent strength and enduring resilience. To understand this transformation, let’s walk through the process step by step.

Step 1

    Before proceeding with any other steps, roll form service providers must carefully select their materials, typically opting for metal strip coils. This choice is strategic: coils are not only readily available but also exceptionally convenient for feeding into the machinery.

Step 2

    The metal, whether stock or custom-shaped, is introduced to an initial set of roller dies crafted to closely embrace its contours. These dies might be positioned horizontally, or they might rotate or roll. Typically, the metal is fed into the machine at room temperature, a process referred to as cold roll forming.

Step 3

    The roll form machine steadily guides the metal through a sequence of rollers, each meticulously positioned a bit differently from the last. This progressive arrangement subtly molds the metal, step by step, into its newly rolled shape.

Step 4

    The subsequent phase, trimming to specifications, is not always necessary. Typically, manufacturers work with endless rolls of metal that are sized down post-roll, a process known as post-cut rolling. This method stands out for its efficiency and uniformity. On the other hand, there are times when manufacturers opt to slice the metal before it enters the rolling phase (pre-cut rolling), allowing them to bypass this step altogether.


Manufacturers regularly produce both standard and bespoke roll-formed products. In sculpting each metal shape, they meticulously evaluate factors such as bend radius, diameter, size, sheet metal thickness, and the material properties of the metal. Roll forming is a flexible, modular process, allowing the machinery to be adapted and re-adapted to craft a diverse array of metal configurations. Additionally, by integrating punching equipment and various other components, roll forming machines unlock a vast array of possibilities. However, their capabilities do have bounds, particularly in creating sealed ring products. Such items necessitate secondary processing, as these machines cannot fabricate closed loops on their own. Instead, ring products need to be either welded or joined with fasteners to achieve a sealed state.

Machinery Used

Rolling Machine

    • The fundamental rolling machine features a series of distinct stations: an entry point where metal is inserted, a roller station tasked with shaping the metal, a cut-off press designed to slice the metal to precise lengths, and an exit section where the finished product emerges.

Many rolling machines are equipped with additional elements and roll form tooling to enhance their versatility. Examples of these enhancements include TIG welding technology, lasers, press brakes, punching tools, and bending tools.

Variations and Similar Processes

Hydroform Press Forming

    Hydroform press forming, commonly known as hydroforming, is a technique where room temperature materials are shaped using high-pressure hydraulic fluid. Within the mold, the metal conforms to its designated shape. When used with ductile metals, hydroforming presents a cost-effective method to produce lightweight, durable, and structurally robust parts and products. This process is predominantly employed in the automotive industry.


Roll form parts are prized for numerous reasons, including their consistency, precision, and robust construction. This process also brings the advantages of being cost-effective, versatile, and producing long-lasting results.


    To begin with, roll forming is exceptionally cost-effective and profitable due to its minimal scrap production and low energy consumption. The process boasts low tooling costs and utilizes nearly 94% of the material fed into the machinery. Additionally, the continuous production capability of roll forming enables the efficient completion of high-volume orders, further enhancing its cost-effectiveness.


    Furthermore, the potential applications for roll-formed parts are vast and seemingly limitless. Rollers can be treated with non-reactive powders or oils, ensuring that the surface properties remain unaffected. This allows roll-formed parts to undergo coating, polishing, finishing, curing, and other treatments effectively. Additionally, due to its modular nature, the roll forming process can be continuously reconfigured, allowing for customized roll forming to meet specific needs.

Durability by Compressive Stress

    Ultimately, regardless of the specific characteristics of a roll-formed part, both manufacturers and customers can trust that the compressive stress used in its creation ensures it will be robust and long-lasting.
