Sheet Metal Gauges
There   are   sheet   metal   gauge   charts   all   around,   but   I wanted   to   do   one   of   my   own.   Gauge   charts   contain   the   standard sizes   and   their   decimal   equivalent.   But   in   the   real   world   the sizes   are   different.   When   calculating   developed   lengths   and specially   if   you   are   creating   3D   models   of   sheet   metal   parts it   is   “ALWAYS   BEST”   to   use   the   actual   thickness   of   the material.   For   example,   I   don’t   know   how   many   times   I   get   a   3D model   that   is   16GA   cold   roll   steel   and   the   engineer   used   a thickness   of   either   .060   or   .063,   not   know   that   in   the   real world   that   steel   sheet   is   going   to   be   more   like   .055   or   .056 thick. d
