I drilled a hole in the sheeting slightly larger then the screw and counter sank the hole. Then I drilled a hole smaller than the screw into metal. I used small flat head sheet metal screws they screwed into the soft metal easy. The screws showed but with the counter sank holes they passed my wife inspection. I think you could drill a hole slightly larger than the screw in the sheeting and then use a self tapping screw. Hope this helps.
