This part has more angles than a LinkedIn thought leader.

The thick-cut steel bracket has multiple precision bends, mounting holes, and triangular cutouts. From laser cutting to forming, Approved Sheet Metal built it in-house from start to finish.

Some parts are here to look pretty. This one’s here to hold something together.

“Close enough” is a perfectly fine standard for lots of things, whether it’s parallel parking, a haircut, or guessing how long the leftover pasta has been in the fridge.

Getting ready for surgery is not one of them.

The sheet metal parts behind medical carts, monitor enclosures, IV equipment, and tubular frames need to be precise, durable, corrosion-resistant, and built to withstand real-world use. That’s why material and finish selection matter so much in medical fabrication.

At Approved Sheet Metal, we fabricate precision medical components and assemblies using materials like 316 stainless and 5052 aluminum, along with finishes chosen for corrosion resistance, sterilization compatibility, durability, and cleanability.

Save "close enough" for the leftovers. See how we fabricate for medical: https://www.approvedsheetmetal.com/blog/industry-spotlight-sheet-metal-fabrication-for-the-medical-industry

“Just use steel” is the material-selection version of “just wear pants.”

Which, yes, obviously.

But for what? A wedding? A construction site? A swamp? The answer changes the pants.

It also changes the material:

→ Stainless steel is a smart choice when appearance matters and corrosion resistance is important.
→ Cold rolled steel is known for excellent flatness, smooth surface finish, and strong press brake formability.
→ Steel like galvanized or galvanneal is a reliable option for structural parts and many appearance applications.

If you want the part to perform the way it should, material choice is one of the first decisions worth getting right.

A sticker peels off somewhere between your shop floor and the job site. A stamp is there to stay.

This video shows how quick and effective metal stamping can be when it’s handled in-house.

At Approved Sheet Metal, we use metal stamping for part numbers, origin marks, logos, and ID marks. Whatever needs to stay on the part permanently.

This customer wanted “Made in USA.” Fair enough. It is.

Happy National Ballpoint Pen Day.

The person clicking a pen in a meeting is the most annoying person alive. I think we can all agree on this.

But the pen itself has a flawless assembly. When done right, it’s a bunch of small parts working in perfect sequence, hundreds of times a day.

That’s the goal with sheet metal assemblies. You shouldn’t have to think about whether they work. They just should.

At Approved Sheet Metal, we handle assembly in-house, combining laser cutting, forming, welding, hardware insertion, and finishing to deliver complete assemblies fast, from prototypes to low-volume production.

If your current process ends with “some assembly required,” we should talk.

We don’t play baseball in the shop.

(Too much metal. Ricochet concerns.)

But according to Russell, our team “knocked it out of the park.”

We’ll take it.

From concept design and material selection through delivery, we helped turn an unfamiliar sheet metal project into a finished product that met the mark on accuracy, form, and quality.

One leg out of the blanket is probably humanity's oldest thermal management system.

Too hot? Leg out. Too cold? Leg in. Repeat until 3 a.m.

It may not be scientific, but it's deeply understood (and effective).

Sheet metal enclosure design deals with the same basic tension. Seal it too tightly and heat builds up inside. Add too much ventilation and dust, moisture, and debris can find their way in.

We wrote a guide to getting that balance right, from ventilation methods and airflow paths to common mistakes and fabrication considerations.

Cyclists will spend six months researching how to shave a few grams off a bike.

They’ll compare frame materials, brake setups, tire pressure, aerodynamics, derailleur alignment, and whether the bottle cage is creating unacceptable drag.

Honestly, we can respect that. Because tiny details matter, especially when the goal is consistency.

That’s what ISO 9001:2015 brings to custom sheet metal fabrication: a documented, repeatable process that keeps jobs moving from quote to ship without relying on guesswork, memory, or “yeah, I think we covered that.”

This is a custom sheet metal base, finished in a blue you can spot from across the shop floor. Folded, welded, drilled, finished, and painted, all in-house.

We make custom parts every day. This one's just photogenic.
