one metal spiral stair tread

[hawkscoach]

Looking for one metal stair tread. Pole is on left as you move up the stair. I redid an outdoor metal spiral stairs for my garage, however, I was short one tread. Also missing the railing. I could make the tread, however, it would be easier if someone had one at reasonable cost. I am in the northern Maryland area. Many thanks

thanks,

Doug
