So just what is a Cold-Formed Frame/Pole Barn Combination Structure? Just as it is defined, Cold-formed steel, also known as CFS, or even metal stud framing, is manufactured steel products that are produced through cold-working processes such as stamping, rolling, and shaping. A pole barn is simply as it states. It’s a post-frame construction. It’s useful if you want to build strong structures in the fastest amount of time and in the most economical way. Marry these two together with both wooden poles for columns attached to the same cold-frame trusses and you have a Combination Pole Barn and Cold Form Frame structure resulting in a stylish looking custom building.
