What Ive learned on steel aircraft hangars
Steel is cost efficient because it is both relatively inexpensive to produce, and it is very durable. Unlike wood or other natural materials, steel is not prone to rotting, termite infestations or other related structural issues. In addition, steel is stronger than wood, which translates to wider, higher, and generally bigger dwellings that are still safe. Often since you need fewer joints and support within steel, you will need less steel to construct in proportion to what you would use with wood. You may be surprised to know that steel buildings are very environmentally friendly.
