As my garage floor attracts puddles at the least excuse, the news of the coming deluge has me worried. I want to use self tappers to fix a rubber strip along the bottom of my garage door. I expect to need a metal strip to screw through and hold the rubber firmly in place. To reduce the need for drilling Im hoping to buy a long strip of metal of a lacey structure but I can't think how to word the search to find such specific material. Any adivice available?
