And the first to incorporate cold bending of steel, and the first vertical-lift bridge to tuck its machine rooms under the bridge. A triply innovative play!
Designed by Theodore P. Zoli, the first structural engineer to win a MacArthur “Genius” Award, this truss bridge eliminates the gusset plates typically used to connect beams and girders to columns . . . → Read More: The First Gussetless Truss Bridge in the World
The Midwest (and beyond) has been plagued by months of drought followed by severe floods causing evacuations, limiting barge traffic on its rivers, and disrupting farmers’ planting schedules. And it may not be over yet: additional rain may cause rivers to remain high into May. Both cities and rural areas have suffered.
Steel fabricators provide part of . . . → Read More: Of Floods, Droughts and Floodgates
If one were to place bets on where you could easily observe curved steel sheet in its end use, the clothing section of a department store such as Macy’s or Dillards would probably be your last wager. If this were the case, you could end up in the hole some, as all you would have to . . . → Read More: Steel Sheet Curved into Cones for Attractive Clothing Displays
A common application for steel beams is for tunnel arches. Tunnels are used in underground storage vaults, in mining and in pedestrian pathways and vehicular roadways.
One of the largest underground storage vaults ever constructed is the site for burying nuclear waste at Yucca Mountain, Nevada. Curved steel beams support the main tunnel of the Exploratory Studies . . . → Read More: Steel Beams for Tunnel Shoring
Stainless steel metal sculptor Mike Helbing – like many artists before him – turned to a company that specializes in the bending of pipes to curve 1 1/2″, 2″ and 3″ schedule 40 stainless steel pipe to create a beautiful wave. This is a dry sculpture for now, but it will eventually become a flowing fountain. The wave . . . → Read More: Curving Stainless Steel Pipe to Make Waves in the Art Community
With ever increasing concerns about sustainability and a way for University of Chicago to allow their students to engage in hands-on experience in the fields of engineering, business and finance, the University devised UChicago Solar. UChicago Solar team was developed in 2011 as an answer to the lack of an engineering program which has given the . . . → Read More: Bending Tubing for the University of Chicago Solar Car Team
On display at the London Olympics, the competitive sport of fencing is based on three disciplines each with its own steel weapon size and style.
From left to right, epee, sabre, and foil
Those of us in the metal business are familiar with many of the different grades of steel that have been developed and improved over . . . → Read More: Specialty Steels Used in the Olympics: From Epees to Barbells
Engineers are constantly striving to improve their designs and this is true for those who design antennas.
The requirement: 3 segments of 16 x 8 x 0.375 rectangular tube curved the hard way (i.e. x-x axis) to a 63ft 7.89in inside radius with 30ft of outside arc.
The application: curved tubes to support a dish for a prototype . . . → Read More: Bending Rectangular Tubing for a New Antenna Design
Roller/benders in the steel industry (those who specialize in curving steel) often work with miscellaneous and ornamental fabricators providing them with helical stair stringers to create circular stairs. Most often these circular staircases are rather large, suitable for a ballroom or spacious, multi-story atrium. Indeed they are called “monumental stairs.”
The most common circular stairs, however, are much . . . → Read More: Circular Staircases Large and Small
When it comes to choosing between spiral lockseam pipe and straight-seam lockseam pipe for your metal duct work, you should consider several factors.
Straight-seam Lockseam Pipe
1. Straight-seam pipe is smoother and therefore avoids any buildup in crevices that is more likely to occur with spiral pipe.
Interior of Spiral Lockseam Pipe
2. Spiral pipe is . . . → Read More: Metal Duct Work: Spiral Lockseam Pipe vs. Straight-Seam Lockseam Pipe
