Industrial Structures

Industrial structures made of steel are known for their durability, strength, and adaptability. They offer cost-effective and sustainable design solutions for various stakeholders involved in construction projects. Steel is easily produced in large quantities and can be prefabricated, ensuring uniform quality and lightweight designs. It is also beneficial for transportation and handling due to its economy.

The erection or installation of steel structures is quick and straightforward. Additionally, steel is a highly sustainable material that can be recycled, making it the most recycled material on the planet. Being a non-combustible material, it provides long-term safety for occupants.

Steel, an alloy of iron and carbon, is widely used in the manufacturing industry. It is employed in the production of various items ranging from small screws and nails to large-scale infrastructure like bridges and railroads. However, steel is prone to corrosion. Over time, it can develop a layer of corrosion, resulting from a chemical reaction when the metal is exposed to oxygen.

Corrosion is a natural occurrence that transforms refined metals into oxides. It happens when a metal, like iron, comes into contact with oxygen. When oxygen interacts with the metal, it causes the metal to oxidise, forming corrosion.

Paints or coatings are commonly used on steel in general atmospheric environments to prevent corrosion. These coatings serve three main purposes:

  1. They act as a physical barrier, preventing oxygen and water from reaching the metal.
  2. They act as electrical insulators, slowing down the electrochemical reaction that leads to corrosion.
  3. They contain active ingredients that gather at corroded sites and inhibit further corrosion.

Industrial structures refer to steel fabrications utilised in marine structures (such as ships, offshore installations, and wind farms), petrochemical facilities, and general construction buildings. Some of these structures are exposed to highly corrosive environments. Therefore, it is essential to regularly monitor and maintain the coatings to ensure that they continue to protect the structures throughout their design life.
