From stadiums to private homes, steel is used as a primary component in wide array of structures. Since a steel building can be pre-fabricated and erected quickly, companies find such buildings highly suitable for the 21st century markets in which they must complete.

Once the steel frame was popularized a century ago, it was no longer a tall order to construct huge buildings. Thus the birth of the skyscraper. With old-fashioned techniques, it was hard to build more than a few stories up, as the weight of so many floors would cause a building to collapse.

Steel building has grown in popularity because steel possesses chemical and physical characteristics that make it an ideal construction material.

The chemical composition of steel is mainly that of iron, but the key to the process is the presence of carbon. The iron atoms form sheet-shaped structures. In pure iron, those structures would slide by each other and make the material soft, but in steel, carbon atoms defray such sliding movements and make the material exponentially stronger.

A steel building manufacturer uses this basic formula to craft different types of steel. The main frame for a steel structure requires remarkably hard, strong steel. Yet for other parts of a building, flexible and/or light-weight serves as a superior composition.

By varying the iron-carbon ratio in the steel, a metal building company can ensure the creation of a product suitable for a wide variety of different purposes. Carbon content impacts factors including the steel's ductility, elasticity, durability, yield strength and tensile strength.

-- The tensile strength is often referred to as ultimate strength, and indicates how much tensile stress a steel product will endure before breaking.
-- Yield strength measures how much stress the steel can take without being vulnerable to permanent deformations.
-- When the carbon content of steel is increased, the hardness of the steel follows suit, however it also becomes more brittle than before.
-- Therefore, as a general rule, commercial steel building products containing ample amounts of carbon will be extraordinarily strong, but they will also be inflexible.

One can purchase a steel building without ever understanding or worrying about terms such as ductility and tensile strength, but knowing how steel actually works - and the variants that separate different steel products from one another - ensures you will make the optimal decision.

By understanding what type of steel you should look out for, you are less likely to end up dealing with an overpriced, low-quality product or working with a steel building manufacturer that does not accommodate for your needs.
