A steel building is basically a structure which is made by steel for both the exterior cladding and internal support. In around 1960’s the term “pre-engineered steel building” emerged. The term applied to the new generation of future steel buildings that have evolved because it was based on standard engineering designs that were applied to a small number of buildings. The application at that time was limited in size and shape. New technology has emerged and that expanded the “clear-span” or no interior support column capability of the steel buildings.

The advent of the computers brought about modern steel building which are developed with computer aided design. Computerization brought about new trends in design which allowed for virtually limitless possibilities in size and shape for steel building projects. Computer Aided Design (CAD) steel buildings brought about much safer designs.
Accurate computations on the allowable loads for wind and snow have increased with the calculations provided by CAD. The advances led also to a more efficient process in manufacturing as most future steel buildings are pre-fabricated. Normally, smaller pre-fabricated steel buildings are simple enough to be done via “Do-It-Yourself” way construction method. The larger steel buildings require professional construction workers to ensure proper assembly.

Smaller building design styles are based normally on the strongest architectural design of the arch. Mostly every steel building is backed by a 20 to 30 years warranty. Computers have made an important impact in the development of the future steel buildings.
