Inquiry (采购产品): J channel I am creating new sign structures for sign material 10mm thick. I need aluminum channel to either weld or rivet to aluminum structures. Sigms will slide in the channel top and bottom. I was thinking 2"x1" by 1/2" channel but am looking for your input.I will need about 500' for building a prototype.When all is perfected I will need 5000'. Please give your suggestions on the thickness of the metal it will only be holding the sign in place not structural. Pease contact me.
