Steel Vs. Galvanized Steel Strength | Sciencing
Steel and galvanized steel strength comes from the thickness or gauge of the steel and the amount of carbon added, not the galvanization process which is simply a coating to prevent rust. Carbon added to iron during the smelting process makes iron stronger.
How to Determine the Shear Strength of a Fillet Weld | …
That would depend on the size of the fillet weld. You can design a weld to give you only the strength that is required to carry the load imposed on it. If the weld must be 3/16″ and you go with 1/4″ you will have a different safety factor than if you go with a 5/16
