Modular Buildings

Modular structures are constructed in-house with final assembly occurring on-site, where the modules are stacked and connected together. Modular construction is a process in which a building is constructed off-site, under controlled factory conditions, using the same codes and standards as conventionally built facilities – but in lesser time. Buildings are produced in “modules” that when put together on site, reflect the identical design specifications and intent of the most sophisticated site- built facility – without compromise.

Let’s have a look at the advantages of Modular buildings:

Greener: The factory-controlled process generates lesser wastage, eradicates site disturbances and allows for tighter tolerances.

Faster: Construction of modular buildings in factory occurs simultaneously with assembling at site, allowing projects to be completed in half the time of traditional construction.

Smarter: Modular buildings are built with the same materials and to the same standards as conventional construction methodology.

Modular Buildings are built with hollow steel sections and cast steel connectors, then joined with bolts to create complete buildings. Trends for affordable housing with low construction cost & faster completion is picking in India. Many cities are facing underground water shortage due to concrete based construction. So, steel based construction should be promoted. Modular Building using structural steel will be the future construction methodology.

Benefits of using steel in Modular Building:

Fast Project Completion: Project duration significantly reduces when structural steel is used in construction of Modular building.

Lower Project Cost: Structural steel reduces the project cost and generates faster revenue.

Minimal Wastage: Use of structural steel reduces wastage while construction. The off-site fabrication process results in less material waste than conventional site-built construction.

Environmental Friendly: Conventional construction methodology causes severe pollution & loss of ground water.

Flexibility in Design: Use of structural steel in Modular Building gives flexibility to create unique structures.

Longer Span: Structural steel allows increased spacing between structural members and greater spans can be achieved.

Recyclable: Structural steel can be recycled indefinitely.

Role of steel in the automobile industry

Role of steel in the automobile industry

The automobile industry manufactures and sells automobiles like cars, buses, trucks, and other vehicles. It is one of the key drivers of the economic growth of India. One material that forms the backbone of this industry is steel. It is widely used in the auto industry. Approximately 55% of a car’s weight comes from steel and on average, a vehicle weighs 1200kg – so that’s a large amount of steel.  

Steel forms a significant part of the automotive industry. Owing to its excellent properties, steel is widely employed in the making of vehicle bodies. Steel is very tough and thus is the go-to-choice for making vehicles. It lends strength and ensures safety. Moreover, steel is cost-efficient along with being light-weight. Steel is also easy to weld and can be reformed easily. All these reasons come together to make steel the most favorable material to be used in manufacturing automobiles. 

Let’s take a look at the uses of steel in the making of an automobile: 

  • Structure of the vehicle: The structure of the automobile makes use of a large amount of high-quality steel. One of the main reasons that steel is used in the making of body frames is because of its ability to absorb the impact energy produced in a crash. This ensures safety. It also keeps the overall structure lighter, yet sturdy. As the steel has high tensile strength, it works in favor of the vehicle and enables it to withstand tremendous pressure and force. 
  • Propeller shaft: High-quality steel is used for the construction of a propeller shaft. It is because the propeller shaft should be powerful enough with a high wear-resistant property so it can tolerate bending and torsional load. 
  • Seat frame: The seat frame too utilizes steel. The reason being, steel is strong and this makes it possible for the seat to withstand everyday rigors. Moreover, steel can be easily formed into the desired shape for comfort. 
  • Exhaust Tubes: These too are again made of steel.  

From the total amount of steel used in an automobile, 34% of it is applied in the body structure, panels, trunk closures, and doors. Apart from that, the drive train makes use of 23% of the steel. Another 12% is used in the suspension. The rest of the steel is utilized in the making of the fuel tank, wheel, steering, and braking system. Thus, steel forms an integral part of the automobile industry.
