Structural Steel: A Brief Overview
Structural steel is usually carbon steel, which means it has a chemical composition holding both irons as well as carbon. It is any class of steel with a carbon content equal to 2.1% of its total weight.

What is structural steel applied for?
There are a diversity of structural steel grades, the most common being ASTM A36 plus ASTM A572. These along with other structural steel grades are predominantly used to construct frames of buildings as well as bridges. They are also employed in the creation of Construction equipment.
Structural steel is used almost everywhere. These days, practically all industries have the most important applications of structural steel. From industry tools to finished products, structural steel is employed all over the place. Buildings, high-rise buildings, bridges as well as warehouses are made thru structural steel sections. Industry experts choose the application of structural steel over any other construction material for building. This is mainly on account of the countless benefits structural steel offers. On the other hand, as with everything else in the world, there are a few shortcomings in using structural steel in building edifices. Here we are going to emphasize the advantages as well as disadvantages of structural steel buildings.
Advantages of Structural Steel Buildings
Steel is flexible. It contains a high strength-to-weight ratio which denotes it has high strength in every unit mass. Thus no matter how large the whole structure is, the steel segments will be small as well as lightweight, different from other building materials.
Steel can be simply fabricated and produced enormously. Steel segments can be formed off-site at shop floors and at that moment assembled onsite. This saves time and improves the efficiency of the complete construction process.
This steel is very supple. You can cast it into any shape, without altering its properties. You can change it into sheets or turn it into wires according to the design.
It is fairly cheap contrasted to other building materials.
It is very tough. Structural steel constructions can endure external pressures for example earthquakes, storms as well as cyclones. A powerful steel structure can end up to 30 years in case maintained well.
Disadvantages of Structural Steel Buildings
1. Steel is an alloy of iron. This marks it vulnerable to corrosion. This difficulty can be solved to some degree thru anti-corrosion applications.
2. It has high maintenance prices since it has to be painted to create it corrosion-resistant
3. There are wide-ranging fireproofing costs engaged as steel is not fireproof. In great temperatures, steel drops its properties.
4. Buckling is a concern thru steel buildings. As the length of the steel column raises the chances of buckling also raises.
5. Steel has a high expansion rate to changing temperatures. This can be damaging to the whole structure.
