I have been looking around on line for suppliers or specifications for a channel and hat channel ceiling system. Everything for drywall seems to be a t channel like a tile suspended ceiling. The problem is that the bar joists to hang from are 6' on center and the max span between wires is 4 feet. Does anyone know who still makes the c chanel system?

For suspended grid (drywall or exposed) where the joist is 6' OC, you start with one wire on the first joist, then two wires on the second, one on the third, and so on. You splay the double wires to obtain code of at least 4' OC. Always run the mainrunners perpendicular to the joist.
