Incorporated: 1972
Another long-standing company with a name you can trust. Definitely a competitive company and I think their roots started off in fasteners and other industrial hardware before branching out into sign brackets. With an advantage in general fasteners no wonder they're able to make it as one of the industry titans.
Top 3 reasons I'd buy from them:
1) They sell a wide range of products even outside of the sign industry which makes them more of a one stop shop.
2) Their prices are very sharp.
3) They've also been around a long time so they are an establish company.
Top concerns about buying from them:
Their product line up is decent but they don't appear to specialize in sign brackets and with their product offering being as wide as it is, it doesn't feel as focused as I'd like it to be to be my top choice pick. Sorry, I'm a sign bracket nerd, so my heart follows those who specialize in the industry.
