I have come across a reference to TERNPLATE in a book first published in forty years ago.

I have not been able to discover exactly what Ternplate is, nor whether it is still available.

A chum suggested asking Mr. Google (who, he assured me, was my friend!) but without success.

What is Ternplate, please?

Is it available in the UK?

If not, is something similar now manufactured under a different name?

I look forward to some light on the subject.

Very many thanks

Do you have any more info to give us a bit of context? Out of interest I did a bit of googling too, as as you say not much is out there other than a mention of it being a type of roofing similar to (or possibly identical to) tinplate.

We used to have a couple of pieces of steel plate called a turnplate or greaseplate which we used to put under the chinook wheel before castoring it 180 degrees; this made it easier to spin the wheel with one person and I guess spared the tyre a little bit too. I suspect this isn't what you are referring to though!

Memory not so good these days but back in the 60s I'm sure we used Terneplate to press Timing Gear Covers for David Brown Tractors, 2 types, Grey in colour, can't remember the gauge exactly but around 18/20 swg EDD sourced from a plant in North Wales in 20 ton minimum lots.

TERNPLATE

Terne coated stainless steel roof panels (Terne coating is a a zinc-tin alloy metal coating process that gives extra corrosion resistance. Terne metals produced acccording to US ASTM A308 are expected to contain alloys copper, nickel, chromium, molybdenum, vanadium, titanium, columbium, and boron, at alloy mixes depending on the specific product requirement.

Worked OK for me. Without the ’e’ comes up half a dozen hits down the list for ‘including terneplate’ on my google.

Thank you all for taking the time to respond.

The reference (in a book about building model engines) was that Ternplate was easy to bend and solder and preferable to Tinplate.

With best wishes and thanks again.

From "Definitions & Formulae for Students – Metallurgy" published by Pitman in 1942 at 6d!

Terneplates – steel sheets coated with a mixture of tin and lead

Probably not obtainable now due to the lead.

.

Interesting to note [now that we know the context of the question] that the text which follows after your quotation is probably of more relevance.

… As per Andrew’s historic reference ; the Lead would be a useful aid to soldering.

From memory, ternplate was used for the bodies of older Landrovers.

From the same book:

Used for roofing, oil paint and varnish drums and in the motor-car industry.

Rod –

Some may have had steel bodies, but I think most of the Series I – III (and the Defender?) LandRovers' panels were made from Birmabright, not steel but an aluminium-alloy, on a galvanised-steel frame.

I suppose a modern equivalent is Corten Steel, a group of weather-resistant alloys widely used for making shipping-containers, sheds and fences. If not painted, they develop surface rust, but otherwise corrode but much more slowly than ordinary mild-steel.

Nigel,

Yes, now you have said Birmabright, I realise I have misremembered.

I know that for vintage car work where Ternplate was specified coachbuilders now use Zintec sheet, which is I think just mild steel with a zinc coating or plating on it. Seems readily available in large sheets, was given some offcuts and it's lovely stuff to work with, very ductile.

Dave

Solders easily too with Bakers fluid or Fluxite.
