Galvalume Parts

[Charles H Jacobus]

Does anyone use Galvalume body parts in their restorations?

Isn't that what Restoration Design coats their metal in?

[Brad Ripley]

Galvalume is a trademark owned by BIEC International and is 55% Aluminum-Zinc alloy coated sheet steel. It is normally used for sheet roofing and some automotive applications.

Restoration Design uses what they call Gavanneal steel which a pure zinc hot process over steel sheet when is then annealed in a furnace causing the zinc and iron in the steel to form a surface coating. .1 percent alum is in the annealing bath which bonds the coating to the steel sheet. This type of steel sheet is commonly used for automotive sheet metal.

Another is Zincrometal is a zinc-chromium alloy and a topcoat of a weld-able zinc-rich primer. It's similar to above Gavanneal and applied by several different patented processes.

Thanks, guys. I thought perhaps Restoration Design used it but good to know it uses something similar.

As always, Brad Ripley, font of knowledge - I never cease to be amazed

[Mike DeJonge]

Restoration Design uses pre-coated metal. We do not coat it ourselves. It is galvaneal, which is widely used in the new car production, by the big 3. 99 % of our steel comes from the USA

[Charles H Jacobus]

Congratulations Mike and crew! Great stuff to keep more on the road. I wonder if Porsche uses it in its new cars or has another process.

most new car manufacturers use e-coat

[Brad Ripley]

"E-Coat" is not part of the sheet of steel as the other processes mentioned above. It is as a cross between plating and painting, where a metal part is immersed in a water-based solution containing a paint emulsion. An electric voltage is applied to the part causing the paint emulsion to condense onto the part.

[Jim Karaba]

So is Porsche not using e-coat in their new car production. If not what process are they using.

[Martin Benade]

Probably galvanizing or something similar followed by e-coat.
