What’s my roof made of? (1 Viewer)

[Otter Spotter]

My PVC is a Citroen Relay high top and I sometimes use a radio Scanner for listening to Aircraft and I use a mag mounted aerial which will stick on the sides of the van but not the roof. I have checked the roof does appear to be metal but not magnetic, any ideas ?

Auminium or an alloy?

My magnetic roof mount aerials stick fine to my 2017 Citroen Relay

How do they weld Ali to steel?

It won't be welded. It will either be physically connected via fasteners of some type or glued. Most probably a combination.

If the roof is aluminium.

Is it actually welded? I don't know whether they do weld it.

Even steel - steel they bond the side and roof sheets to the struts

I believe on most there are still spot welds.

Yes could well be, and lots of gloop to help. When we put our windows in our pvc , had to navigate round the stuff.

In general aluminium and steel can be done bonded. Jaguar do it a lot on XEs etc.

Thought I had better clarify. Was watching a youtube video about just this not so long back.

They use the glue to make the bond. But to hold it in place while it sets up and locate it properly they use spot welds.
