Roll Forming Stainless and Aluminum

Roll forming machine for stainless steel and aluminum


Stainless Steel and Aluminum are strong yet malleable metals. With its vast array of processing capabilities NKS provides quality material fit for your intended application.

A great use of the flexibility of Stainless Steel and Aluminum is the process of Roll Forming. Roll Forming steel is the continuous bending of a metal strip at room temperature. This process progressively shapes the metal until it achieves the desired profile. Tandem sets of rolls progressively shape the metal until the desired cross-sectional profile is achieved.

Virtually any Stainless Steel or Aluminum that can be formed in sheet-form can also be Roll Formed. Roll Forming is an ideal process when producing long lengths of metal or large quantities. Therefore, it is a preferred technique in large volume projects.

What are the benefits to rolling forming?

Roll Forming has a number of benefits including:

  • the technique can produce material in a variety of lengths from the same roll set
  • it has a high productivity rate
  • the process can reduce packaging and shipping costs
  • multiple manufacturing operations can occur on Roll Formed material, in-line, effectively reducing manufacturing costs.


Stainless Steel and Aluminum Roll Forming is used in the manufacturing of medical devices, food handling equipment, dairy equipment, and chemical equipment. This material is also applied in sectors such as Aerospace, Appliance, Automotive, Construction, Energy, HVAC, Solar and Tube & Piping.

Roll Formed Steel

Stainless Steel and Aluminum are often selected for the Roll Forming application because of their resistance to corrosion and performance under heat. There are a few types of Stainless Steel and Aluminum that are often sought after for this intended application. In Stainless Steel Austenitic 200 and 300 series is often used in Roll Forming because Austenitic Stainless is ductile. Specifically, 304L and 316L Stainless are often selected for this application. Type 304L Stainless Steel is the most widely used of the austenitic (chromium/nickel) Stainless Steels. In the annealed condition it is essentially non-magnetic and becomes slightly magnetic with the application of cold work. Type 304L Stainless Steel is preferred in welding applications to exclude the formation of chromium carbides during cooling in the heat affected region of the weld. These alloys represent an excellent combination of corrosion resistance and fabricability. Type 316L Stainless Steel is an austenitic chromium nickel Stainless Steel containing molybdenum. This addition increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. These properties are similar to those of Type 304L except that this alloy is somewhat stronger at elevated temperatures. Type 316L Stainless Steel is an extra-low carbon version of Type 316L that minimizes harmful carbide precipitation in the heat affected zone during welding.

While Stainless Steel boasts increased strength because of its chemical components, Aluminum is a far more malleable metal. Roll Forming of Aluminum is easier than Stainless Steel. That said, increased attention must be paid to setting and adjusting roll gaps to prevent surface marks. The 3000 series alloys, specifically 3003, 3004, and 3105, are used most frequently by Roll Formers. NKS Alloys provides top quality anodized aluminum products in both clear and unsealed, and in a variety of colors. Anodized Aluminum is available in gauges varying between 0.012″ to 0.125″, in sheet or coil form. NKS Alloys can provide either large or small quantities of this material.
