Steel has been used in construction since the first skyscrapers were built in the late 19th century. But recently, it has become an option for smaller buildings and even residences.
Structural steel is commonly used in high-rise commercial and industrial building construction primarily because of its high strength, toughness, rigidity, and ductile properties. Structural steel is the most cost-effective framing material. Structural steel members are fabricated in structural H-beams, I-beams, and T-beams, which are used as structural load bearing members. Structural steel fabricated off-site under controlled conditions reduces costly job site modifications.
This material provides strength that is unavailable for buildings made with wood framing and brick walls. It does not warp, buckle, twist, or bend and it is flexible and easy to install. Because of its increased quality and ease of maintenance steel is an attractive building material. On top of that, it is mold- and mildew-resistant, a plague that sometimes affects wood-framed buildings. Steel is sturdy enough that it resists the damage caused by natural disasters, such as tornadoes, hurricanes, and earthquakes. It also makes buildings a lot more resistant to fire and termites. Because it is highly durable, insurance premiums can be lower for buildings where steel is used.
