Talk:Tread plate

Untitled

The inventor of treadplate was a man named Colin Meek in 1938. He designed and manufactured the very first piece in his welding/fabrication business named Oakhurst Metals, which is situated in England. He had a 'gentleman's agreement' with an american business which offered to mass produce his new innovate treadplate. The american business however took all the samples of his product and filed for a patent, which was approved and then treadplate became the americans product lawfully and it became trademarked. They never spoke to each other again and Oakhurst metals went bankrupt. — Preceding unsigned comment added by 165.225.16.216 (talk) 06:41, 2 November 2019 (UTC)

Steel plate

I'm not sure who deleted the stub on diamond plate.
I've changed the page to a disambiguation page.87.102.3.9 15:45, 18 October 2007 (UTC)

Size specifications

I'm trying to find out if eg 2.1mm checker plate is at least 2.1mm plus the bits that stand out, or if 2.1mm checker plate will take up no more than 2.1mm, therefore the actual load bearing sheet is thinner. — Preceding unsigned comment added by 1.124.104.74 (talk) 08:02, 9 June 2019 (UTC)

Decorative?

Why is it used vertically on emergency vehicles? Just for decoration? Seems like it would add a lot of weight. — Preceding unsigned comment added by 98.249.51.66 (talk) 01:41, 30 August 2011 (UTC)

New stub

I've written a new stub. I think this deserves discussion as a motif, if not the history of diamond plate and the variations. I will take a picture at work of it's proper use (stairs). I can't find anything on the history of diamond plate, i'm sure it's related to industrial safety so maybe it originated in the late 40's early 50's? Not sure it's something that has been researched. If you have complaints, you know how to find me. Codeczero (talk) 22:42, 12 April 2008 (UTC)

I suspect that diamond plate predates the 1940s. It may have originated as early as the 1920s as a hot rolled steel plate product. I, too, have been unable to find anything on its history. The term "diamond plate" may have started as a trademark and later became genericized, much like "scotch tape" or "kleenex" (uncapitalized) have entered the vernacular. A cursory search of the United States Patent and Trademark Office database on "Diamond Plate" and "non-slip" didn't turn up anything relevant, but that doesn't necessarily mean that a company such as U.S. Steel, BethlYogiBearehem Steel or Republic Steel didn't use it as a marketing term originally, without actually having registered it with the USPTO, while patenting the design under an entirely different name. It's also quite possible that the concept didn't originate in the United States. It could have been developed for the railroad or shipbuilding industries, both of which have needs for non-slip surfaces. For an early example, see U.S. patent D54285 (1919) by Walter J. Spiro for a non-slip running board molding design.
The current photo of diamond plate, obtained from Flickr.com, is a design not commonly seen these days. The more common pattern is usually called "A36 Carbon Steel Plate", "A36 Steel Floor Plate", or "A36 Diamond Plate", referring to the ASTM A36 Standard Specification for Carbon Structural Steel. There may be another ASTM document that covers standard shapes and patterns, but since ASTM publications are only available for sale, not free, I'm not about to run out and buy a copy for the purposes of writing this article. Perhaps a Wikipedian who works at a company that maintains copies of the standards in-house could look it up. This information may be useful in further searches on the origins of the material. — Quicksilver^{T @} 17:31, 18 August 2011 (UTC)

Sometimes I see also "tear plate" as a synonym for checkerplate, is this correct English?

Perhaps the origin of diamond plate is 19th or early 20th century and the original name comes from the textile industry where a checkered pattern (Checker board) gave the name checkered plate. This would make the name checker plate older than diamond plate. A historical search for "checkered plate" or "checker plate" may give better results than looking for "diamond plate". This also is assuming the origin is American or British. There are German, French, Italian innovations, that could have originated this form of non slip plate. — Preceding unsigned comment added by Yg-greg (talk • contribs) 21:16, 23 May 2014 (UTC) Yg-greg (talk) 21:19, 23 May 2014 (UTC)

Older water trapping checker plate, possibly referred to as 'Diamond Plate'.

Potentially incorrect statement

In the article it is said that tread plates offer “little to no slip resistance”, the reference however, states the opposite. Im not sure which is true by if it’s the former, a source material confirming it seems necessary. 217.173.178.22 (talk) 14:53, 21 February 2025 (UTC)

Seconding this. Article is misleading with no support for the statement of "no slip resistance". 204.191.241.26 (talk) 17:45, 10 April 2025 (UTC)

Reverted their changes. Their only other edit was reverted for shilling on the article for a different type of floor plate. 204.191.241.26 (talk) 18:19, 10 April 2025 (UTC)

Tread designs?

I would be interested to see specifications for different tread designs if they exist, for artistic purposes. I'm not sure if the rounded designs are circular (vesicas), parabolic, or undefined curves. Some are diamond, though they seem fairly less common. Sometimes the treads come in sets per checker, and I wonder if there is reasoning for this beyond aesthetics.

Maybe see alsos for tactile paving, stair tread, and anti-slip gratings could be added too. Dunda02 (talk) 01:38, 30 October 2025 (UTC)
