I have had a lot of trouble finding any material properties info on galvanized steel. I also would like any info on galvanized tubular steel or galvanized steel extrusions. I would appreciate any advice, thanks.
The galvanising process does not change the base metal properties. Piping will be supplied to US or British Standards usually to Grade 200 MPa Yield Strength. Rolled platework will also come in nominal 200 MPa Yield.
If you need anything more specific than that you may need to do a tensile test on a sample, or contact the Steel Supplier.
