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 Read more…


Expanded metal can be curved, bent, or rolled to different curvatures without any major distortions to the diamond-shaped pattern. Expanded metal is made from sheet metal uniformly slit and stretched. Expanded metal is a form of metal stock made by Read more…


Did you know that a task that’s interrupted takes much longer and has more mistakes than an uninterrupted one? A machine operator who is working on a project can get into a focused state where he is able to concentrate Read more…


Angle iron is a common standard structural steel shape. Angles are L-shaped cross sections made by hot or cold rolling at the mill. The most common angle iron used for manufacturing OEM products in the USA is A36 a standard Read more…


Quality is the essential aspect of all services rollers/benders provide. The simple definition of quality is conformance to the customer’s specifications. In the case of curved steel sections, the dimensions specified would typically be on detailed fabrication drawings. The drawings Read more…


When structural engineers are developing large new buildings or reconstructing existing ones, columns are chosen to provide stability to the structure and to distribute load-bearing capacity throughout the building.  For columns to be functional and visually attractive, architects usually choose Read more…


Some structural steel fabrication drawings have material specifications that are probably incorrect.  For example, many architects and engineers mistakenly detail their drawings calling for the use of pipe with an A53 vs. A500 grade specification in their bill of material. Read more…


A wiper die is a tool in a rotary-draw-bending machine set up that prevents the deformation in the form of wrinkles that occurs when the material exceeds its elastic limit and sets in the curve.  As the pipe is drawn Read more…


The definition of a radius of a circle is the length of a line from the center of a circle to its perimeter.  When measuring a curved steel section (e.g. a curved steel angle, beam, bar, channel, etc.), you can Read more…


When a metal tube is bent, the cross section material fibers experience tension on the outside of the bend area and compression on the inside of the bend area.  Wall thickness on the outside cross section of the bend will Read more…
