see the thing is my bmw has got "duplex double row chains" so why would they say it twice if you get what I mean?
Because most people dont know the difference between simplex and duplex.
And they are Germans.

We supply stainless lifting chain to the nuclear industry, so they definitely make itDuplex is a type of stainless steel.
But in this case it's one row of chain or two rows of chain.
I know a bit about duplex stainless steel, one of the uses is to make the boxes that radioactive sh!t is stored. Radiation is my specialist subject
Pretty sure they don't make chains out of it, is bloody expensive and a pain in the arse to work with.
I think that in the case of the steel, some manufacturers just adopted the term 'duplex' as a brand name for a particular product with high chrome and molybdenum content (i.e. "double" the chrome, but it's usually a bit less than double). It doesn't necessarily mean that a double or 'duplex' chain will be made of it. They probably aren't, becase they go rusty if you leave them outdoors, so mostly they're not stainless at all.
i used to work for "simplex" when it was part of the gec group....we made milking machines, grain storage silos and similar stuff.
in the wider sense simplex, duplex,triplex are just words that mean the same as single, double and triple
hence a bike chain with one row of rollers is referred to as a simplex chain....one with three rows of rollers side by side is a triplex chain....the metal its made of dont come into it
Yup, we had duplex chain in my mother's old Morris Oxford. Then when I was a bit older we had a Wolesley Six with more cylinders but a single chain. I built the remains of the engine into a wall at my parents old house. The cylinder head made a really good cornerstone and the diff ended up as a finial on an arch over the garden gate. I think I've got a duplex on the TD5 but I haven't needed to get it out yet fortunately.
