Torchcraft cuts most outdoor signs from 3/16-inch (7 gauge) new plate steel.  Indoor signs may be cut from 1/8-inch steel.  It's easy to see from the photo the difference in thickness of Torchcraft steel vs the "other guys".  Most other artist cut from a flimsy 14 gauge steel such as the one pictured above that I picked up from a local art show.  When you think about your metal sign, do you want one as thick as a paper clip or one that is 109% Thicker?
