I have a heavy pot rack to mount on a kitchen wall. The instructions say to mount in solid wood. I plan to attach two boards to the wall and mount the pot rack on them. But the wall has metal studs, not wood. I have never worked with metal studes and am concerned that if I attache the wood with drywall screws it won't hold the weight of the pot rack and pots. Anyone have any experience with metal studs and heavy loads. For instance, can I run lag screws into the studs and have them hold the same way they would in wood?
