They first gained popularity in the early 20th century. Their use became more widespread during World War II and significantly expanded after the war when steel became more available. In the last few decades steel buildings have become more common as their capabilities have expanded with improved designs due to the availability of computer aided design programs.

Some common types of steel buildings are "straight-walled", "arch" and "clearspan". Straight-walled and the arch type refer to the outside shape of the building. Steel arch buildings are the most cost effective and structurally sound. They are commonly used in the agricultural industry. Straight-walled buildings provide more usable space when compared to arch buildings. They are also easier to blend into existing architecture. Straight-walled buildings are commonly used for office space.

Clearspan classification refers to the internal construction. Clearspan steel buildings utilize stronger overhead support beams, thus reducing the need for supporting internal columns. Clearspan steel buildings can be used to store large commercial aircraft or used as public arenas.

 

Steel buildings become much safer with Computer Aided Design

The modern steel building is composed of many individual segments that have evolved over time. With the recent benefit of Computer Aided Design (CAD) steel buildings have become much safer. The maximum wind load and snow load in particular have increased with the more accurate calculations provided by CAD.

These advances have also led to a more efficient manufacturing process as most steel buildings are pre-fabricated. The smaller pre-fabricated steel buildings are simple enough to be constructed by anyone. The larger steel buildings require professional construction workers to ensure proper assembly.
