Rolled and Welded Cylinder Fabrication: A Guide for Engineers and Buyers
At Toledo Metal Spinning Company, we manufacture custom rolled and welded cylinders for a wide range of industrial applications. Our capabilities support customers in industries including aerospace, agriculture, automotive, building and construction, HVAC, and general manufacturing.
Rolled and welded cylinder fabrication provides flexibility in material selection, diameter, length, wall thickness, and custom features. Using precision forming, welding, and secondary manufacturing processes, we produce cylinders designed to meet the dimensional, performance, and application requirements of each project.
Capabilities & Commonly Formed Materials
Cylinder products are produced from a variety of materials, including, but not limited to 1100-O, 3003-O, and 6061-O aluminum, carbon steels 1008-1020, CDA 655 copper, 655 and 718 inconel, and stainless steel series 304, 304 DDQ, 316, 410, and 430.
These materials possess similar properties such as excellent formability, weldability, and strong corrosion resistance. Cylinders can be furnished with custom features including ribbed, custom formed ends, fittings, side holes, and weld flanged options. Forms are created by rolling flat sheets into a round shape, then sealing with a seam weld produced with Jetline TIG welding equipment. Once the metal cylinder is welded, the planishing operation also realigns the molecular structure of the metal to its original state. Our processing yields accurate dimensions, with smooth, strong weld seams.
Size capabilities for cone and cylinder parts are up to 72 in. in length, diameters from 5.5 to 48 in, and thicknesses from 0.030 to .134 in. The tightest tolerances of ±0.030 in are met for parts up to 1 ft in length, with higher tolerances for larger parts. Turnaround times are 2 to 4 weeks, and all parts and processes meet ISO standards as well as our own internal standards for excellence. Value added additional services include secondary forming, welding, metal finishing, engineering support, stamping, embossing, extruding, and, of course, spinning.
There are cut out, edge, profile and welding options available to customize the cylinder for a specific metal fabrication application. Toledo Metal Spinning Company forms and welds high quality sheet metal cylinders to work with other TMS products. Double flanged cylinders are used as non-welded spacers to extend the height of the deep drawn cups and hoppers. When welded construction is preferred, either a plain or single flange cylinder can be TIG welded to either the conical or flat cylinder ends. Using the cylinders in conjunction with our stock metal spun hoppers, deep drawn cups and stainless steel lids will permit a rapid development of a vessel that can be used for several applications mentioned below. For more information about our custom cone and cylinder fabrications or our other available services and products please see the table below or contact us directly.
Common TMS Metal Cylinder & Ring Configurations:
- No flange metal cylinders.

Cylinders can be formed in a variety of configurations, including no flange, single flange or double flanges. Cutouts, doors, windows, steps and ribs. Beads can be formed on the flanges or the body of the cylinder.
Toledo Metal Spinning’s engineering team looks for ways to produce parts in the most economical fashion possible.
How Rolled and Welded Cylinders are Manufactured?
Rolling
We can roll up to 6’ in length with up to a 4’ diameter. The thickess can range from .032” thick to .250” thick with materials like cold rolled steel, hot rolled steel, various stainless steels, and aluminum. Copper, brass, and Inconel are also available to roll.
Tabbing
Once the parts are rolled in the Davi roller, we take them over to the tabbing station to tab each end of the cylinder. The tabs are welded to the ends of the cylinder to prevent “blow through” on the cylinder ends. The seam welder will initiate the weld on the tab outside of the main cylinder and continue seam welding throughout the length of the cylinder and onto the exit tab.
Longitudinal Seam Welding
In our large roll and seam weld cell, we have a state of the art Davi roller. The large longitudinal seam weld cell can roll a minimum of .032” thick up to .250” thick by 6′ in length and 5′ in diameter.
Planishing
Once the seam welding is complete, the cylinder is taken over to the planishing machine to flatten the weld to near flush with the cylinder. Then, the cylinder goes to the cutoff machine to remove the tabs. Voilà! The cylinder has nice and even ends.
Flanging
At this point, the cylinder could be finished or it could go to the flanging process. We are able to make a single flanged cylinder or a double flanged cylinder. The customer can choose what flange radius they would like. The standard choices available are 1/4”, 3/8”,1/2”, 5/8”, or 3/4”, the radius depends on the material type and thickness. Typically, a radius of at least three times metal thickness is acceptable.
Lean Manufacturing ; One Piece Flow Technology
Instead of batching parts between each machine, one part is fabricated at a time so that when the part comes out of the cell, it is complete and ready to ship or go to the next cell or department. This method of manufacturing reduces the overall time that it takes to make a completed part.

Frequently Asked Questions about Rolling & Seam Welding Metal Cylinders
Rolled and welded cylinder fabrication is a manufacturing process used to produce cylindrical metal components from flat sheet or plate. A flat, precision-cut blank is formed into a cylindrical shape and joined along its longitudinal seam using a controlled welding process.
This method is well suited for custom cylinders where diameter, length, wall thickness, material, and additional features need to be tailored to a specific application. Depending on the design, cylinders can also incorporate formed ends, flanges, fittings, ribs, openings, and other secondary features.
Rolled and welded fabrication can be a practical choice when a cylindrical component requires a specific diameter, length, material, or wall thickness that may not be readily available as standard tubing.
It can also be advantageous for larger-diameter or custom-shaped components where manufacturing from flat sheet provides greater flexibility. The ideal fabrication method depends on factors such as part geometry, material, production volume, tolerances, and required secondary operations.
Rolled and welded cylinders can be manufactured from a variety of metals, depending on the required dimensions and application. Common materials include carbon steel, stainless steel, aluminum, copper, brass, and Inconel.
The most useful information for specifying a rolled and welded cylinder includes the finished diameter, overall length, material type, material thickness, and required tolerances.
It is also helpful to identify any additional features, such as flanges, formed ends, ribs, fittings, holes, cutouts, or welded components. Drawings, CAD files, and application requirements can provide additional information needed to determine the appropriate manufacturing approach.
The Custom Cylinder Configurator makes it easy to design required specifications and dimensions with an instant quote and drawings.
The longitudinal weld joins the rolled sheet along its length and becomes an integral part of the finished cylinder. A controlled welding process helps produce a consistent seam while maintaining the required dimensional characteristics of the component.
Welding requirements can vary depending on the material, thickness, cylinder dimensions, and end-use application.
Planishing is a finishing operation performed after welding to reduce weld buildup and create a smoother transition between the weld and surrounding base metal.
For rolled and welded cylinders, planishing can improve the surface profile of the longitudinal seam and provide a more uniform finished surface. It can also reduce the amount of additional grinding or finishing required, depending on the application's specifications.
Yes. Rolled and welded cylinders can be manufactured with a variety of additional features depending on the part design and manufacturing requirements.
Examples include formed or flanged ends, ribs, fittings, holes, cutouts, and welded components. These features can often be incorporated into the fabrication process or completed through secondary manufacturing operations.
Providing the complete part drawing or dimensional requirements is the best way to determine which features can be incorporated into a specific cylinder design.
One of the advantages of forming cylinders from sheet or plate is the flexibility it provides for custom dimensions. The practical diameter and length range depends on the material, thickness, equipment capacity, and geometry of the finished component.
For projects with unusual dimensions, providing the desired diameter, length, material, and thickness allows the manufacturer to determine whether the design is appropriate for rolled and welded fabrication.
Rolled and welded cylinders are formed from flat metal and joined along a longitudinal seam, while seamless cylinders are produced without a longitudinal welded joint.
The appropriate option depends on the application's requirements. Factors such as pressure, material, dimensions, tolerances, production volume, and cost can all influence which manufacturing method is appropriate.
For custom industrial components, rolled and welded fabrication can provide flexibility in diameter, length, material selection, and additional features.
Both processes can produce cylindrical or round metal components, but they form the material in different ways.
Rolled and welded fabrication starts with flat sheet or plate that is formed into a cylinder and joined along a seam. Metal spinning forms a metal blank over a rotating tool to create a round, axisymmetric component without requiring a longitudinal seam.
The right process depends on the geometry, dimensions, material, production requirements, and performance specifications of the part.
The cost of a custom cylinder can depend on several factors, including material type, material thickness, diameter, length, production volume, tolerances, welding requirements, and secondary operations.
Additional features such as flanges, formed ends, fittings, holes, cutouts, machining, or finishing can also affect manufacturing cost.
Providing a complete drawing and material specification allows the manufacturing team to evaluate the part accurately and identify the most appropriate fabrication process.
