Steel plate rolls–whether they have two or three bottom rolls–all have a top roll. The top roll can be sized to roll plate into cylinders or cylinder segments to radii close to the diameter of the top roll. However, relatively small top rolls can deflect in the center under the pressure of curving steel plate. Alternately, . . . → Read More: Why Crown Your Plate Roll
The construction of steel tanks for the storage of hazardous materials must be done carefully. The tanks’ seams are often considered to be a potential point of failure. For structural reasons, therefore, tank construction with as few seams as possible is desired, and, when possible, single seam construction is preferred. But this single-seam requirement can be . . . → Read More: Rolling Single-Seamed, Thin-Wall, Large-Diameter Steel Tanks
Bollards are usually a post or other metal or concrete structure that helps define a physical space–think of the posts put up at key buildings after 9/11.

But bollards date back to ancient Rome where they served as road markers. Recently we had an opportunity to . . . → Read More: Large Bollards Made From Formed and Rolled Metal Plate
The underground mining/boring industry has always employed some of the most creative, hands-on workers. One entrepreneur in Missouri used a rolled and welded plate cylinder as the base ring for a 36″ diameter drill bit for underground directional boring. Welding hardened steel cutting teeth to the ring made the product very cost effective. The 3/4″ x . . . → Read More: Angle Rings and Rolled Plate Cylinders: Creativity in the Underground Mining Industry
Designers, detailers, and fabricators commonly debate the correct formula for a blank length of bent plates. A trial run is always good practice when forming on a press brake because metals stretch so differently on different setups.
This confusion does not need to carry over into the rolling of plate, since the radius is larger than 3 . . . → Read More: Calculating the Developed Length of a Rolled Cylinder
A common application for curved stainless steel sheet and plate is in the brewing process. And craft beer is one of the fastest growing segments in the beverage industry. In 2011, the industry experienced 13% growth; in 2012, 15%.
To meet that demand, new breweries are constantly opening, and existing breweries are adding tanks to increase their . . . → Read More: Bending Stainless Steel Sheet and Plate for Breweries
Most curving of steel discussed on this blog is done on section benders or plate rolls. But curving steel plate through the use of a press brake with radius dies is also done. As the ram presses the steel plate down with a convex die, the plate is pressed into a matching concave die to achieve . . . → Read More: Putting Curves in Steel Plate by Bending on a Press Brake
Rolled steel shapes, whether used in construction or as component parts of equipment, are often welded together to form rings and cylinders. Different metal fabricators perform different types of welding depending on their expertise and their customers’ requirements.
For example, companies that make cylinders for pressure vessels often have the plate rolling capacity and code welders to . . . → Read More: Welding Steel Shapes that Have Been Rolled
Steel cones have many uses: as ornamental iron components, as funnels, as chutes, and as transitions in metal ductwork to name just a few.
Steel plate is formed into cones primarily by either rolling the plate in a plate roll or forming the plate with radius dies in a press brake. Some companies “step brake” lines into . . . → Read More: Rolling Steel Plate into Cones
Equipment manufacturers often purchase rolled steel sections–angles, bars, beams, tees, pipe and tube–that are formed to a specified radius by companies that specialize in curving metal.
Especially when developing new curved parts, the process usually takes the form of an engineer contacting the Bender/Roller asking if a particular metal section can be curved to a given radius . . . → Read More: Rolled Steel Sections: Feedback to Suppliers is Critical
