 Sheet steel What's the optimum thickness for sheet steel to weld in patches and strips onto a 2CV floor, bulkhead, etc?
Is it worth the extra cost to buy galvanised? Or is using galv more agro than it's worth?
(Please excuse my rather basic question, but I've never had to buy before. I've always relied on butchering old panels and parts...)

Re: Sheet steel I always go with 0,8mm, anything thicker as a patch tends top cause stress cracks, if your making up full panels such as seat box lower or toeboard then you can up it to 1mm or there abouts. Find a stockholder and you can pick up sheets at about 3'x4' for not much if your lucky you can get Zintec. due to work im always pinching sheets of galv from things like boiler housings or old storage heaters so theres usually a pile of sheet at various thickness for making brackets etc. http://www.mig-welding.co.uk/ are a wealth of info good tutorials and a few "well kent" faces.

Re: Sheet steel Smiffy,
as Sean said, but Zintec rather than galvanized sheet metal.
The former has a coating only 2 microns thick compared with 85 microns for the latter, so it can be welded 'as is', without having to grind away the coating prior to welding.
Galvanized sheet needs to be treated with mordant solution before painting otherwise paint will not adhere, whereas this doesn't seem to apply with Zintec.

Re: Sheet steel I tend to prefer 1mm as it is stiff enough for most patches but still easy to forge and form..... .8mm is really nice to form but doesn't always feel substantial enough, but is great for most applicationsespecially compound curves......i've never tried zintec, sounds good though...

Re: Sheet steel I tend to use filing cabinets or kitchen appliances if I have any, buying steel in small quantities is proper expensive.
