Galvanizing question - material thickness

[shoelace]

I am proposing a design for galvanizing where a 1/8" thick 3" box section is welded to the side of a 3/8" thick 4" box section - where one wall of the 3" box is inline with the side of the 4" box - ie. it is off centre by 1/2". The 3" box cantilevers out from the 4" box and is unsupported at the other end.

I understand that the galvanizing process is best suited where wall thicknesses are similar - distortion due to heat input being the concern. Will my particular design proposal be at risk for this distortion?

A good aspect of the design is the use of box section. I have difficulty thinking it will distort when comparing it to a more open section design.

Any thoughts will be appreciated. Thanks.

I'd call your local galvanizing shop;

http://www.galvanizeit.org/.

It seems that an 1/8 inch is not too thin, but they'd know for sure.

Thanks for the galvanizing link - very useful.

I suppose what I want to know in simpler terms is:

Does distortion due to dissimilar material thicknesses occur in box section construction? ... or this distortion more unique to open sections, flats etc?

I'll also pose the question to my local galvanizing shop as you suggest.

Thanks
