These are made from small I-beams and have 5"x5" plates welded to them with pre-drilled 1/4" holes (with screws included!) so that you can use them right away for your projects. (remember to pre-drill the holes in the wood!) The legs are 15" tall, which is perfect coffee table height. If you need something heavy duty, or just simply want to achieve that industrial, modern look with your tables/benches, our I beam legs are the way to go. These small I Beams are 3" x 2.75." The height pictured is 15", but we can create them at any height, which works well for smaller as well as larger tables.
