message: The way this is written, it implies sheet metal has only been around since 1500 AD... pretty sure that's not true...
Yeah I'm pretty sure the Japanese had that covered since day one.
Fair point, but what metals were used, were any of them alloys and what was the standard thickness(es) - or just an example of that available in an influential province; or a locality with, say, a concentration of master craftsmen - in the West, ‘blacksmiths’ I guess.

message: The gauge section didn't explain 'gauge' entirely.
Seconded - having read this : . . .
"The weight of steel per square foot per inch of thickness is 41.82 lb (18.96 kg), this is known as the Manufacturers' Standard Gage for Sheet Steel"
I still have no idea what Gauge actually means.  How could I use that to work out what thickness 18 gauge is. I find it hard to believe that an engineering unit is both arbitrary and non-linear - is it a left-over from an earlier age ?
I answer my own question. Yes, gauge is both non-linear and arbitrary.  See http://en.wikipedia.org/wiki/American_wire_gauge.  I'll edit the article  — Preceding unsigned comment added by Fentlehan (talk • contribs) 14:57, 19 March 2013 (UTC)
replies: text: Archaic my ass. It's still the most common and easiest way to order sheet metal. The little twits in their ivory towers may squeal "archaic" but those of us who work with sheet metal do not. Metric sucks. 116.231.74.1 (talk) 12:27, 2 February 2017 (UTC)
replies: text: Then you will easily appreciate that those of us who grew up with metric system want to know exactly what we are dealing with once we move to US or Canada, see "28 gauge" in the store, and wonder how thick that is. 172.103.222.67 (talk) 00:54, 9 December 2023 (UTC)

message: They pre date 1500. If you consider things like breastplates and helmets it is more like thousands of years before 1500AD.
:Sheet metal is a product of the industrial revolution.  The article is not discussing forged products, or thin metal in general.  Sheet metal is the specific product produced by rolling lines: long, thin, and coiled metal hundreds of meters long. - Toastydeath 01:27, 30 July 2007 (UTC)
replies: text: This is an old topic but still relevant and I see where the OP is coming from.  The article starts off by saying sheet metal is just that, nothing about it necessarily being made by an industrial process. --Una Smith (talk) 20:32, 10 November 2008 (UTC)

text: It's probably done based on geometrical constraints and FEA analysis. They used the FEA to figure out optimal depth to gain the most nominal stiffness. It's also dependent on manufacturability. --Wizard191 (talk) 15:50, 4 June 2008 (UTC)

message: The article sheet metal forming is just a partial list of processes, just like the one here. However, the list in sheet metal at least has an introduction for each. I don't see any reason why there needs to be a separate article to list the same things. Wizard191 (talk) 00:32, 24 July 2008 (UTC)

message: Can anybody tell me up to what thickness the piece is called sheet metal after that up to what it is called plate and above what thickness it is called a metal block?  —Preceding unsigned comment added by Kiran engr (talk • contribs) 06:06, 4 March 2009 (UTC)
replies: text: The introduction covers that information. Wizard191 (talk) 15:06, 4 March 2009 (UTC)
replies: text: The main article seems to describe thickness in terms of gauge (probably quite similar to the use of that term when describing wire).   But I am curious.  Is it common to find thicknesses of 10.1 gauge, or 10.25, or 10  1/3 gauge?   I think the main article could be improved if there were a discussion of the various kinds of sheet metal when laid over each other, or pressed together so tightly they fused.   216.99.219.53 (talk) 21:27, 5 September 2009 (UTC)

text: I think that suppliers are very reliable. I use their information on a daily basis to design parts accurately. If their information were inaccurate, that would be a good way to lose business. If you don't think its a reliable ref, please post something at WP:RSN. Wizard191 (talk) 16:44, 28 October 2010 (UTC)

message: Could the info under brake press forming not be added to the brake press page, which could then be linked to from this page as per the other methods? The cutting section is also quite poor.

message: It seems like an encyclopedia article on sheet metal should include at least some reference as to how it is manufactured.  So much of the article is devoted on how to form it, but how does it come to be in the first place?  — Preceding unsigned comment added by 65.0.202.234 (talk) 01:47, 17 June 2012 (UTC)
replies: text: Agreed. Incidentally, the early versions  of this article appear to have some information on the manufacturing process, and its history. Cesiumfrog (talk) 02:10, 30 December 2013 (UTC)
thread_title:  Manufactured how? 

message: "Usage of steel as a building material is popular as a cost effective, quality material as compared to the alternatives.[2] The three most common stainless steel grades available in sheet metal are 304, 316, and 410.[3]
Grade 304 is the most common of the three grades. It offers good corrosion resistance while maintaining formability and weldability. Available finishes are #2B, #3, and #4. Grade 303 is not available in sheet form.[3]"
Is "303" a typo for "304"?
:A quick check only of McMaster.com shows 304, 316, and 410 available in sheet form. 303 is only available in bar stock. So the statement is correct, but perhaps not useful.Jim1138 (talk) 19:57, 7 July 2014 (UTC)
