Default Zink steel

I have two questions regarding sink coated steel
First does the hot zinc coating on steel interfere with the jaws on a shrinker stretcher machine
Second is it recommended to use zinc steel for auto restoration?

Thanx
Mick

To answer your second question, you have to clean the zinc off to weld it, and the fumes are poisonous. Personally I would not use it.

I have been using it for the last 10 years. I only just started to think maybe I shouldn’t.

Default Zinc

Zinc will plug up your shrinker jaws, and is slippery and will cause them to slip as well.

By welding or brazing zinc sheets, the temperature can rise enough to vaporize the zinc and if you breathe it , can give you "zinc chills."
Welding galvanized steel can also give you zinc chills if you do not wear proper protective gear.


Soldering, riveting and bolting zinc clad sheets recommended.

i have been looking at the steel sheets as well Mick.


the GT40 i want to build calls for the use of EN2B sheets, which is an old english standard.



comprising carbon 0.15 max
Manganise 0.50m
Sulfur 0.05
Phosphorus 0.05


i am not sure what sort of sheets you can get in South Australia, but i havent found any EN2B in Melbourne.


i have been going through the bluescope steel site.

I haven't got much past that at the moment. Since this will be forming the monocoque chassis, i am considering the cold rolled CM350-G, which as a 350MPA strength. My only concern is if i will be able to form it easily.
