U.S Sheet Metal Gauge: Explained

#sheetmetal #sheetmetalGauge #sheetmetalgauges
ASTM standards for sheet metal gauge thickness and sheet metal gauge chart formula/ how to find the weight of a given gauge.
Micrometers are often used (better than vernier calipers) for measuring this thickness value: amzn.to/2E9yZYy

Thank You for this Absolutely Excellent video Brother

[@AvivMakesRobots]

You got it!

[@kermitefrog64]

This is good to know since I am getting ready to put on a metal roof.

[@AvivMakesRobots]

Great! Best of luck. Thanks for watching.

thanks very interesting for me

Valuable information

Thank you.

Thanks very

[@AvivMakesRobots]

Sure!

So where does the "20" come in to naming the "20 gauge"? You took the thickness .0359 times the density 41.82 to get the weight per square foot, but none of that involves a "20". So what does the gauge number have to do with anything? 24 gauge is a nice even number of 1 lb/sq ft.

I was told it comes from a fraction, as in 1 over 20 1/20. So like what i've been told about shotguns and their gauge is this. If I start by melting down a pound of lead and start pouring the lead into spherical molds, and I make 20 spheres of lead, then those spheres would each weigh 1/20 of a pound and they would roll freely down the barrel of a 20 gauge smooth bore shotgun or musket. If the balls were larger in diameter and 1 pound of lead made 12 balls, then those balls would weigh 1/12 of a pound and roll freely down a larger diameter, 12 gauge barrel. So in principal, you need to know the density of the metal first. And we're talking the common metals each have their own density. Iron, steel, Stainless, copper, brass, bronze, aluminum, magnesium and the alloys in between. And he's saying "a square foot, one inch thick" Ok so we have a mold to pour the molten metal into just like the spherical mold for the shotgun balls. And we measure the molten metal by weight, we pour it into a mold, and then it fills the mold to a certain depth and cools down to a predictable but not perfect thickness by today's standards. By today's standards giant rollers can extrude and compress sheet metal into any thickness to 3 decimal places give or take half a thousandth.

So... Hol up.. work with the thought of having base material thickness of 0.299 inches? It would sound absurd for me to order sheetmetal which is 7.5946mm thick. When I could just order 6mm or 8mm sheet. I really... really don't understand how you get anything done. Like how the hell do you start to do strength calculations or do math in applied mechanics? All the numbers are neat and tidy in metrics... How... How do you go about with them in imperial? Newton metre is a beautiful little unit that works regardless whether you talk about millimeters or kilometres. In US you use two? Pound-foot and pound-inch, which don't directly translate to each other. How do you get any math done?!

[@AvivMakesRobots]

It's a good question, haha.

[@timd6324]

Well actually we end up doing a lot more math...

[@profile.]

All of these could be expressed in mm worldwide, without any confusion. 🤨

[@AvivMakesRobots]

We need to move on from the imperial system!

[@joshuabond5292]

You shut your mouth.

[@anonimuso]

@@AvivMakesRobots We don't take kindly to your kind 'round here...

[@AvivMakesRobots]

@@joshuabond5292 Lol. "MY DADDY USED THAT IMPERIAL SYSTEM! YOU KEEP YOUR MOUTH SHUT!"

[@AvivMakesRobots]

@@anonimuso We use freedom units! If you don't like it, leave!

[@Vet-zj5lq]

If someone was confused before after watching the video they are going to be a lot more confused

[@AvivMakesRobots]

Haha.

[@Carbide861]

I have a question that I cant find and answer for. I have been under the impression that 7GA and 11GA are 3/16" and 1/8" respectively. I have since come across charts that say 7GA is .1793" and 11Ga is .1196". These are just two examples but I don't know the difference between the two charts and its driving me INSANE. i need some clarification. Here is some reference www.engineeringtoolbox.com/gauge-sheet-d_915.html

[@AvivMakesRobots]

Look at "Stainless Steel" on that chart. Compare the US standard gauge to that. Either way, it should not matter. What matters is the gauge and material you are using, and the thickness for that specific material and gauge.

start using adaptive strip oiling or wiping without any energy, no moving parts, no replacement parts or is exceptionally versatile Equipment which can be easily installed in varied machines

[@AvivMakesRobots]

Pretty cool stuff.

[@rolltechinnovation6770]

Engineering Juice thanks mate, stay safe and stay blessed

Umbrella neels #3

[@AvivMakesRobots]

True. They usually use a very high gauge for umbrella tubes.
