Peugeot chassis galvanised or not?

Hi all was wondering if anyone new what the chassis material was made off on a Peugeot boxer conversion 2018 I was going to lanoguard spray the underside the van for protection against rust not sure if it is galvanised or not thanks in advance

All Boxers have been galvanised since 2008.

Many thanks Paul when I rang Peugeot direct  they couldn’t give me an answer thanks for the reply

It is an interesting question that I have not got round to asking. The word “galvanised” can be misused or misconstrued. Good old “Galvanised” steel is steel that has been hot dip galvanised, i.e literally dropped in a vat of molten zinc (after certain preparatory processes). This results in a thick layer of zinc that is chemically bonded to the substrate steel.

Steel that is zinc plated (“electroplated”) is also often referred to as galvanised. This tends to be a thinner layer, less resistant to corrosion.

You can usually see the difference. Freshly galvanised steel tends to have a flaky mottled colouring, whereas electroplated steel is a more even finish.

This link explains a bit:

Zinc plating results in a thinner coating, but is often a much easier and cheaper process than hot dip galvanising. Hot dip methods can also be difficult on thin metal and/or complex structures since dissimilar heat on either side of a piece of metal can cause the metal to distort. When we used to fabricate closed tanks for boats, that were destined to be hot dip galvanised, we had to design in big inspection plates and suitably placed filler and vent holes so that the tank filled (and drained) with molten zinc very rapidly, allowing the temperature of both faces to change at near enough the same rate.

I suspect that for distortion reasons alone hot dip galvanising would not be suitable for modern pressed steel bodies, although it is OK for things like a Land Rover chassis.

I would far rather have a zinc plated vehicle than a purely painted one, but don’t think that it will still be there in fifty years like a farm gate hinge!

Some parts will still be ungalvanized so why not Lanoguard it anyway, it cant harm.

Wasn’t sure if the lanoguard would affect the galvanised parts has any body used it before many thanks all

I’ve used it, most importantly get it inside the sills, you can remove the bungs to spray inside them

Thanks all for the replies

novice question - how can you tell if the chasis has been galvanised?

I have a 500 ml can of marine grade Lanoguard which I apply with a paint brush to small areas in need of protection like the gas tank.  It can be applied to areas that have already corroded and will slow the corrosion and can be reapplied if there is a need.  I've also used it on things other than the motorhome.  It's a more enduring alternative to spaying with WD40 or grease and dries with a relatively hard surface that won't pick up dirt.  Lanoguard is wax so perfectly harmless and not unpleasant to use.  Having the whole van done would be a good idea even for an older van but I would have that done professionally with the van on a hoist, pre-cleaning and using a spray lance.

Check out Members Factsheets, Executive, a new project, page 2.

Won't let me copy and paste one of the pics here...

Technically the van bodies are not galvanised as, like, say, a farm gate is. They are dipped in a galvanic solution in manufacture. The Alko chassis extension is, however.
