When the Quality of Fabrication Really Counts
In recent weeks an All Metals Fabrication (AMF) employee had the opportunity to travel to Peru where he hiked the Salkantay Trail on the way to the world famous Machu Picchu. The hike was marked by an unexpected landslide which forced his trekking team to cross a large river.
The large river basin from side to side spanned some 300 feet with canyon walls that were nearly vertical. Walking down the trail, the hiking team found a local farmer who had a single metal cable pulled across the river canyon, approximately 200 feet in the air.
For a small fee the farmer would transport the trekking team across the river in his makeshift cart, cable and pulley system.
The deep mountains and rough terrain of Peru are spectacular, but as one might guess, the traditional testing, engineering and requirements stringently applied in places like the US are not readily apparent on a small Peruvian farm.
Through translation, broken English, broken Spanish and many assurances from the farmer, the team decided to use the metal cart and pulley system to cross the treacherous river.
The trekking team considered the obvious questions about safety, knowing that if the cart or cable failed it was likely certain death. Will the welds hold together on this cart? Is the metal in good condition? Is the metal cable securely fastened? Is the metal cable secure in the cemented structures? All of these were discussion points before the decision was made to go.
Happily, everyone passed over the river safely and the smiling farmer made a good amount of money for his service.
AMF takes these exact questions very seriously as we fabricate parts that HAVE TO WORK! Every day we fabricate parts for roller coasters, transportation vehicles, ski lifts, play ground equipment, railing, guarding, conveyors, automation, paneling, etc.
We track our materials from their origin, we have established weld certificates and processes (WPS and PQRs), we have check points and quality assurance documentation all aimed at delivering components that have passed our fabrication and safety standards so you don’t have to worry if your theme park ride is safe. Because we all know hikes and rides are much better when you can do them more than once!

How to Move Continuous Improvement Past Flavor-of-the-Month Status
Continuous Improvement is one of those corporate buzzwords that most of us have often heard but few of us have experienced—at least not longer than a flavor-of-the-month initiative.
Many companies, including those in the metal industry, recognize the value but the tough part is trying to execute on Continuous Improvement until it actually becomes part of the fiber and sinew of the organization.
AMF determined a couple of years ago—after a few false starts—to drive this concept into the soul of our company. The jury is still out as to whether we have accomplished that extreme goal but there is no doubt that Continuous Improvement has pierced the armor of our company culture and is heading toward the heart.
How have we accomplished this cultural implementation? Perhaps the biggest key was starting from the bottom (where the good ideas really germinate) and working up.
Some of the key implementation strategies have been as follows:
- Create a cross-functional Continuous Improvement Committee that meets weekly, which does not mean every other week, every week when things are not busy, every week when every person can attend or every week when everyone is in the mood. It means every week no matter what!
Consistency is perhaps THE biggest key and right behind it is having a cross-functional team, consisting of shop and management, that has the autonomy to debate, discuss, agree and disagree about ideas and concepts.
- Recognize that small improvements are worthy of consideration—even simple suggestion like brooms, fixing small leaks or changing very minor work processes are very important. Those tiny improvements add up over time. They build upon each other. Small suggestions often lead to bigger breakthroughs (things that cannot be seen until someone takes the time to notice the impact of a small change.)
- Every suggestion, no matter how small, big, or brilliant (or even not brilliant) needs to be recognized and acknowledged. Without recognizing each suggestion, the Continuous Improvement concept turns into an old-fashioned idea box (that never gets checked and therefore never get stuffed with ideas.)
- Create an easy way for employees to submit ideas—particularly right at the moment the idea strikes them. We have implemented a CI Hotline where employees can use their smartphones to snap a picture and then text the idea the moment it happens.
- Finally, all the ideas, improvements, implementations, etc. need to be communicated inside the company in a major way. We spend resources marketing to our customers—our people need the same. AMF has set up internal Walls of Fame that we update consistently to communicate how improvements are being made and implemented.
The bottom line is we are trying to create more value for our customers and employees by getting better every day. Continuously Improving a metal fabrication company, like any other, is best accomplished by valuing what every employee might suggest, even from the smallest corner of the business.
Technology Does Not Supplant Craftmanship
Technology certainly has an incredible impact on any industry—the metal fabrication industry is no different.
To that end, AMF employs the latest technology in every possible situation—one example includes our latest 60’ long x 8.66” diameter, five-axis tube laser. Still, even with the greatest and latest technological advances, AMF fosters real attention to craftsmanship and quality.
We back that claim in the undercurrent of both our company mission and vision statement. Our mission, in short, is the never-ending pursuit toward improvement. Our vision, summarized, is about being the absolute best company in our industry.
On the shop floor, we refuse to call our people fitters or welders—instead, they are fabricators or craftsman.
We believe that technology makes us price competitive and efficient fabricating steel, aluminum, stainless steel and other materials but craftsmanship and quality make our work stand above others in the industry.
Any company can fabricate parts—we want to fabricate results that make our customers smile and feel at ease. That is a brand promise that we recognize will be tested over and over, but we are not shy about saying as much.
Frankly, we don’t want customers, we want partners. We want to be part of a supply chain that is seamless and easy—one that creates real value for all parties.
We invite you to explore AMF and figure out how a customer-vendor relationship can turn into a real supply chain partnership.
Metal Fabrication Trends: What’s Next?
The metal fabrication industry has seen growth in jobs and technology over the past several years. Although there was some anticipation about possible impacts with the new administration change, overall manufacturing has seen positive growth over the past year. Let’s take a look at rising metal fabrication trends.
The State of Metal
As a whole, metal manufacturing is in good shape, although recent government intervention and Trump Tariffs are causing big concerns about the future as steel and aluminum prices have surged at record rates. Hopefully, steel and aluminum fabricators will see continued strong demand as the market adjusts to these new pricing realities. The good news is that the economy overall is boiling at a good rate — shops are busy and demand is strong.
Creating a highly skilled workforce in the United States is critical to job growth in America. Over the past five years, more than 265,000 jobs have been returned to the U.S. The reshoring trend is due in large part to new technology, automation and advances in speed and productivity, as well as rising costs overseas. This reverse trend is vital to restoring a vibrant U.S. economy, and hiring high-quality metal fabricators to fill worker shortages is at the core of success.
Automation has helped simplify all forms of metal fabrication. The industry is thinking in new ways about merging worker productivity and automation.
Tube Laser Technology
Tube laser technology introduces several significant advantages over traditional manufacturing and fabrication processes. Tube lasers increase the ability to produce more intricate cuts, increase fabrication speed, save on downstream assembly and can reduce costs while improving quality. Learn how AMF is utilizing tube laser technology in our Utah metal fabrication shop.
Things are looking exciting for the metal industry as metal fabrication businesses invest in 3D printing technology. Metal 3D printing differs from traditional steel fabrication processes as it involves the stamping of metals to produce a required design. The evolution of 3D printing has gone from a product development tool to a full-blown industrial and manufacturing tool.
There are currently 12.3 million manufacturing jobs in the U.S., and the metal fabrication industry ranks third in providing manufacturing jobs in the U.S. The global metal fabrication market is expected to exceed $21 billion over the next five years. The metal fab industry includes all forms of fabrication: tube laser, metal cutting, metal forming, CNC fabrication, welding, punching, metal finishing and more. There are a number of opportunities for growth, as long as we are willing to adapt to rising metal fabrication trends.
Tight Fabrication Tolerances Are Often Unnecessary and Always Expensive
Ah yes, the title block at the bottom of the print clearly spells it out: +/- .005 fabrication tolerances for anything with three decimal places…and every dimension on the print goes out three places!
But (there is always a but) how many engineers and designers realize that one little box at the bottom of their print—usually from a default template—can drastically change the cost of their designed part?
Speaking about metal fabrication specifically (not machining), tolerances as tight as .005 can be very arduous and many times completely unnecessary.
Unfortunately, many engineers design these constraints into their work unknowingly, which nearly always leads to significantly higher priced parts—sometimes as much as double.
Engineers should consider that metal fabrication shops work with cutting, forming, sawing, punching and welding—all these processes are a far cry from milling, lathing, drilling or boring.
Fabricated parts are usually assembled with fasteners and welds while machine parts are assembled with pins and intersecting pieces—consider, as a simplistic example, the difference between a vehicles metal frame (fabricated) versus the vehicles intricate engine block (machined).
Very simple engineering modifications can help parts and assemblies work without requiring mind-bending fabrication tolerances. Holes, for example, can be slotted or oversized.
On paper the difference seems minimal. That is not true. Most fabricating estimates start right at the title block as estimators check to see what tolerances are required for a successful part. The tighter the tolerance callouts, the more expensive the part will be!
Nearly any professional metal fabricating company would be excited to work with customer engineers and quality teams to collaborate on design tolerances that make sense. Take a few minutes to contact All Metals Fabrication and discover how a few small changes could save your company real money and time.
Tube Laser Work in Real Life
AMF recently won a job from a very significant customer with a worldwide footprint. They wanted approximately 150 each of these vanity support brackets (see drawing) and requested a price.
When we gave them our bid they were surprised at the price. Too low, they thought – and they wanted to be sure we had everything covered. (We did!)
The part is designed for angle iron but because of the 10 EA holes that need drilling into the angle (a major pain in the booty) the customer is willing to concede making the part from flat sheet metal and break-forming the bend. (See Highlight #1 on the print)
Still, they are asking for the edges to be ground smooth—actual call out is a 1/8-inch radius. (See Highlight #2 on the print)
The buyer and engineer have been trained over the years by fabricators that this part would be easier to make from flat sheet metal than angle iron. (That training needs to be re-done, and new possibilities need to be considered!)
With the tube laser, none of these issues exist!
• Tube lasers can cut angle iron easily.
• Tube lasers can cut hole or slots into the angle iron flanges easily (and very accurately!)
• Tube lasers can miter the 45-degree joint easily, while simultaneously chamfer the cut prepped for welding with its 5-axis cutting head.
This is a relatively simple part even with the workaround – but the point is that real-world tube laser technology takes a simple part and makes it even simpler AND less expensive.
Think about it.
Stop for a minute and consider what simple parts can get even simpler with this technology, and you are just scratching the surface of what can be done! Our expert metal fabricators can bring your next project to life. Contact us.
Tube Laser and Welding Technology – How They Work Together
All Metals Fabrication was founded in 1994 and since then, we’ve been a top-tier metal fabrication company. Our two core markets are industrial metal fabrication and architectural metal fabrication. As industry experts, we specialize in fabricating all types of metal including steel, stainless steel, aluminum, copper, brass and more.
Tube Laser Technology
Advancements in tube laser technology have significantly reduced welding and assembly times. Here at AMF, our Mazak Fabrigear II 220 gives us the ability to cut tube, pipe, angle, bar, beam and more in rapid time and with incredible precision. Our customers and even our own internal welding crews have been surprised and thrilled by the incredible benefit, especially when it comes to the downstream assembly of materials – we’ve discovered that welded assemblies happen about 30 to 40 percent faster. For example, a normal assembly that may take an hour to weld can be fabricated with tube laser technology in 35-40 minutes, and two-piece cut can nestle up without so much as a finger to hold them together.
Extreme heat from welding metals together can reach temperatures above 2,500 degrees Fahrenheit. It’s basically melting pieces of metal together. That much heat can distort and warp materials so it’s important to take steps to avoid over-welding, especially if you like straight, square and well fit assembly of parts. Learn more about All Metals Fabrication’s welding processes here.
And here’s how we use tube laser and welding together:
How do you turn 3-inch square tube into a rectangular tube with an integral formed corner? Use a tube laser and some skilled welding! This part that Justin is showingin the photo below started out as 3 x 3 x 0.125 steel tube. A little presto magic on the tube laser with some welding and we ended up with a rectangular shape tube tapering from top to bottom and through a formed end.
The combination of welding and tube laser technology yields endless possibilities—structurally, architecturally, and mechanically. More and more we’re seeing engineers and designers incorporate tube laser technology into welding projects.

Why Small-Sized Channel Forming Can Be A Challenge
Customers are often baffled by an over-the-phone explanation of why certain sized channels cannot be press brake formed. Although press braking appears to be a simple concept, precision accuracy can be quite difficult.
There are a couple of reasons for this but the most significant reason is best illustrated by Figure 1.
If the channel has vertical legs that are too long when compared to the base, the leg formed first will crash into the forming dies before the second bend bottoms out at 90 degrees.
When that happens the metal will crash into the brake or forming dies and the legs or base (or both) will be stretched and contorted, which basically ruins the channel.
Sometimes these constraints can be overcome. Here are some suggestions when forming small-sized or deep-leg channels:
- Custom “dog leg” or “gooseneck” or “swan neck” dies (shown in Figure 2) can often be used or special ordered that allow for tighter formed channels.
Most metal fabricators will have a few sets of standard gooseneck dies for basic channel forming but often times custom sets of metal forming dies will have to be ordered to form and fabricate the parts needed.
These types of dies are expensive, costing several hundred dollars per foot so smaller-sized jobs, particularly non-repeat jobs, are often not quoted because of the excessive cost of purchasing a custom die set.
- Some fabricators will suggest “back-bending” the metal channel, which is also hard to explain verbally but can be attempted.
Back bending works by creating a “W” shape in the formed part and then hitting the channel again with a flattening die to smash the middle section out of the “W” (See Figure 3).
Back bending (see the green shape) keeps the leg of the die from smashing into the crash-point as shown in the illustration. This works well when there may be only a few parts to bend and the fabricator and customer decide, jointly, that it makes sense.
There are a few drawbacks to this method.
One, the metal part will have a line down the middle of the channel where the metal was flattened, which may or may not be important depending on how the part is used. (See red triangle in Figure 4).
Two, this is not a very efficient way of forming parts because it takes several press brake setups and multiple handling of parts compared to basically one set up if the part was formed with the gooseneck dies shown in Figure 2.
All of this is simply to say that forming small or deep channels in sheet metal, as we originally pointed out, is not as easy and obvious as one might think.
Hopefully, this will help you as you work with your local metal fabricator.
Future metal fabrication and press brake forming topics that relate to this will include forming fractures (when metal actually fractures or breaks as it is formed), minimum forming dimensions (what is too small to form) and forming to inside or outside dimensions.
Sheet Metal Fabrication and Ironwork: What’s the difference?
It may seem that sheet metal fabricators and ironworkers have similar jobs. Both are highly skilled trades but they actually have different skill sets and utilize different tools and materials. Typically, ironwork is more structural and sheet metal fabrication is more functional. Both types of metal fabricators work with a variety of metals, machinery and equipment.
Historically, ironworkers fabricated with wrought iron, but today’s skilled craftsman work with a variety of ferrous and non-ferrous metals on heavy-duty projects. There are three main types of ironworkers.
- Structural ironworker
- Ornamental ironworker
- Reinforcing ironworker
As you might guess, structural ironworkers erect the framework of bridges, buildings, stadiums, amusement park rides, bank vaults and other large-scale industrial metal projects according to engineer blueprints. They may also load and unload equipment, operate hoists and forklifts, place pre-cast concrete slabs, and perform industrial maintenance.
Ornamental ironworkers, or finishers, are responsible for the more architectural metal metal elements such as window frames, stairways, catwalks, railings, fencing, gates and building entranceways. These projects can be fabricated from a variety of different types of metals and are usually welded or bolted to the main structure. Ornamental ironworkers are highly skilled at arc welding.
The main job of reinforcing ironworkers, a.k.a. rodbusters, is to strengthen structures. These are the workers who place and tie rebar, and reinforce concrete footings, slabs, bridge framework and building structures.
Some people say the biggest difference between ironworkers and sheet metal fabricators is the height they work from the ground!
Sheet metal fabricators
These skilled tradesman frequently work in metal fabrication shops or at manufacturing plants. They may specialize in fabrication, installation or maintenance, but may perform tasks in all three areas. Sheet metal workers may fabricate metal roofs and rain gutters, heating and cooling systems, handrails, auto parts, and more. There are as many types of sheet metal as there are types of metal, including aluminum, steel, stainless steel, zinc, copper and a variety of alloys. Sheet metal fabricators take into consideration metal thickness, tensile strength, manufacturing method and quality.
