So I was looking around at Home Depot yesterday and saw that they have 2 3/8" x 8ft sections of galvanized steel. I'm pretty sure it was supposed to be used for fencing. How well will that work for a DIY rail? I'm looking for a cheap catch free way to build a backyard rail.
Not sure, but if you look closely at Galvanized Steel it isn't really that smooth. The coating is kinda layered onto it. I wonder if a gas line pipe, usually black'ish wouldn't be better and nearly same price. Also available at Home Depot or any other large box store.
