Today, practically all industries have major applications of structural steel. From industry equipment to finished products, structural steel is used everywhere. Buildings, bridges, high-rise buildings, and warehouses are made using structural steel sections. Industry experts prefer the use of structural steel over any other building material for construction. This is mainly because of the innumerable benefits structural steel provides. But as with everything else in the world, there are certain downsides to using structural steel in building structures. Here we are going to focus on the advantages and disadvantages of structural steel structures.

Steel is tensile. It has a high strength-to-weight ratio, so it has high strength per unit mass. So no matter how large the overall structure is, the steel sections will be small and lightweight, unlike other building materials.
Steel can be easily fabricated and produced massively. Steel sections can be produced off-site at shop floors and then assembled onsite. This saves time and increases the efficiency of the overall construction process.
Structural steel is very flexible. You can mold it into any shape without changing its properties. You can convert it into sheets or turn it into wires as per the design.
Structural steel is relatively cheap compared to other building materials.
It is very durable. Structural steel structures can withstand external pressures such as earthquakes, thunderstorms, and cyclones. A well-built steel structure can last up to 30 years if maintained well.
Steel is an alloy of iron. This makes it susceptible to corrosion. This problem can be solved to some extent using anti-corrosion applications.
It has high maintenance costs as it has to be painted to make it corrosion-resistant
There are extensive fireproofing costs involved as steel is not fireproof. In high temperatures, steel loses its properties.
Buckling is an issue with steel structures. As the length of the steel column increases, the chances of buckling also increase.

Steel has a high expansion rate with changing temperatures. This can be detrimental to the overall structure.
Steel is one of the most common and important construction materials. This is evident in the current demand for steel today. The popularity of steel is largely due to the many benefits it brings to a structure. However, there are some disadvantages when it comes to using standard steel that make weathering steel an ideal choice for building material.
You are probably familiar with the combination of properties that make steel an advantageous construction material relative to other building materials. First and foremost, steel is an extremely high-strength, durable and flexible material that is significantly lighter than other materials, such as concrete. These properties work together to increase the safety of the project, lower the costs of overall construction, and allow for faster construction.
Another popular property of steel is its versatility. Not too many building materials are as versatile as steel. Steel can be cut and molded to fit different designs, which gives architects more creative freedom to accomplish their vision for the structure.
While there are many advantages of steel construction, there are a few disadvantages to take into account. Unlike concrete and wood materials, steel is notorious for rusting in certain environments. Consequently, the costs of painting and maintaining a steel structure can be high. Steel can also be a conductor of heat, which means it needs to be adequately fireproofed. And lastly, steel can be susceptible to fatigue, fracture or buckling due to manufacturing inconsistencies.
With weathering steel, you reap all the benefits of standard steel construction and more. Unlike standard steel, weathering steel can be used unpainted in structural and architectural applications, which eliminates painting and maintenance costs while reducing overall construction time in the short and long-term.
While weathering steel is silver in its original state like standard steel, it develops a patina over time that serves as a protective, corrosion-resistant barrier. The naturally-developed patina regenerates continuously when exposed to weather and stops further access of oxygen, moisture and pollutants. This patina layer is not only practical, but its rustic, orange-brown color blends also well in many environments from natural areas and contemporary interior design.
The corrosion-resistant and aesthetic benefits of weathering steel appeal to many, and weathering steels have increased in popularity over the years. Builders, architects and landscape designers utilize it for various applications in both commercial and residential projects. From roofing and siding to building facades and bridges, here are a few ways weathering steel is commonly used in construction.
