galvanizing "grades"
does anyone have any information on galvanizing "grades"?  specifically, whats the difference between g-60 and g-40?  and is there an a-60 or a-40?  which is the "better" galvanizing?
try the following link for information on hot dip galvanising:-
us steel has a good web page for galvanizing grade reference:
excellent site, mattman, thanks.
pylko...the designations "g60" and "g40" refer to hot dip galvanizing average weights of 0.60 ounces per square foot (both sides) and 0.40 ounces per square foot respectively.  the metric equivalents are 60 g/sq.m and 40 g/sq. m respectively.
astm standards a525 are the specifications for hot-dipped gavanization.  my version is for 1987.
also refer to astm a446.
distinction of g designation versus a designation is in the chemical.  g designation is a zinc alloy and a designation is for zinc-iron alloy.  i am not an expert on galvanization so i hope you can find what you are looking for in the astm specs.
