When a steel fabricator attempts the bending of beams the hard way (x-x axis or against the strong axis), the result can be an unacceptable crippling of the web. Bender/rollers (those companies that specialize in curving steel sections) use a Read more…


With regards to beam bending or the bending of other steel sections, what is the source of the straight material that will be curved? According to the American Institute of Steel Construction (AISC), 70% of steel used in construction comes Read more…


What is your per pound cost for bending beams? Structural steel fabricators sometimes ask bender/rollers (those companies that specialize in providing curved steel), how they calculate their pricing.  More specifically, fabricators ask for a per-pound cost for structural steel bending.  Read more…


Circular staircases can wind up-right or up-left.  Saying that the staircase curves in a clockwise or counter clockwise direction is ambiguous:  Is it the direction as seen from the bird flying above or as seen from the worm below? Alternately Read more…


A common question regarding the bending of beams is how many passes it takes when using a three-roll bender (also called a “section bender” or “angle roll.”  The answer (like so many answers) is that it depends. Modern benders of Read more…


The bending of beams is usually done the “hard way,” i.e. against the strong (x-x) axis or the “easy way,” i.e. against the weak (y-y) axis.  Beams can also be curved to multiple radii, off axis, and in two planes Read more…


Steel sections are curved in various ways. 1. Rotary-draw and compression bending create a curve by wrapping the steel section around a form to achieve the desired radius.  This method is most often used for round tube bending, square tube bending Read more…


Put most simply, structural steel bending links to the construction supply chain by connecting with the structural steel fabricator.  Profile bending is a service subcontracted by structural steel fabricators, if required for a given project,  just as galvanizing, painting, coating, Read more…


When it comes to choosing between spiral lockseam pipe and straight-seam lockseam pipe for your metal duct work, you should consider several factors.   1. Straight-seam pipe is smoother and therefore avoids any buildup in crevices that is more likely to Read more…
