Steel in construction is renowned for its strength and versatility, and with different steels available to use on your construction projects, it is important to know the advantages and disadvantages of the different steels used. Here are the differences, advantages and disadvantages of structural steel and light gauge steel construction.

What is Structural Steel?

Structural steel creation involves heating iron up and adding certain substances to achieve specific properties. Structural Steel is seen as one of the most important resources in construction, due to its long list of benefits for making building infrastructures extremely strong. Steel is used for large building projects within construction such as multistory buildings, bridges and industrial plants.

Advantages Of Structural Steel

• Strong – Structural steel is hot rolled, and once hardened it becomes incredibly strong. For comparison, a one-inch circular bar that is firmly attached to supports can hold 20 tons.
• Time/cost-efficient – Structural steel is easily produced and put together, as it is created off-site and is assembled on site. This makes structural steel time effective as it speeds up the construction process, in the long run this will also save on cost as time is money in construction!
• Flexible – Structural steel is very flexible, despite being extremely strong. You can mould it into any shape, without changing its properties. You can convert it into sheets or turn it into wires as per the design.
• Cheap – Structural steel is relatively cheap compared to other building materials.
• Durable – Structural steel structures can withstand external pressures such as earthquakes and thunderstorms if maintained correctly.

Disadvantages Of Structural Steel

• Corrosion prone – Steel is an alloy of iron. This, therefore, makes steel susceptible to corrosion (rusting). This problem can be solved to some extent using anti-corrosion applications.
• High maintenance cost – Despite being cheap to make, steel in construction comes with high maintenance costs, as it has to be painted to make it corrosion-resistant – this can become costly over time. As well as the anti-corrosion costs, there is also a high cost that comes along fireproofing the steel. This is extremely important, as in extremely high temperatures steel can lose its properties.
• Lots of high technology needed – Due to its extensive weight, lots of high technology is needed to transport and build the infrastructure, therefore calling upon experts both within the technology and construction will need to be on hand.

What Is Light Gauge Steel?

Light gauge steel (LGS) is cold-formed, which creates long, thin sheets that are then shaped into guided “C” or “Z” patterns capable of holding heavy loads. LGS frames and components are produced and fabricated from structural quality steel coils and are shaped at ambient temperatures by roll-forming machines. Light gauge steel construction is most commonly used in residential or light commercial construction as an alternative to wood framing. It’s similar to wood in that little cutting and sizing is required on the job site because the studs are manufactured to precise lengths

LGS can result in faster build times, lower costs, versatile design solutions and a durable, practical solution to premium buildings.

Advantages Of Light Gauge Steel

• Time effective – LGS can result in faster building times due to there being no on-site, welding or cutting is normally required. This means that the erection process is fast and simple – requiring less labour time-on-site and heavy lifting equipment.
• Versatile – It is able to shape itself to any form, and can be clad and insulated with a wide range of materials.
• Lightweight but strong – Lightweight gauge steel is lighter than wood and is also stronger. This makes it extremely useful when building as LGS forms a very similar principle to wooden framing – members are replaced with thin steel sections. Not only is this easier to build, but is also strong.
• Can be easily modified – It is easy to change or modify this construction at any point in its lifespan. It is able to shape itself to any form and can be clad and insulated with a wide range of materials.

Disadvantages Of Light Gauge Steel

• Can lose properties – Much like structural steel, LGS properties can be lost in the event of a fire.
• Supporting Structures – Steel frame constructions rarely work on their own. They usually require drywall, sheathing, insulation and supplementary wooden components to bring a building together. In the opinion of some construction businesses, this longer construction time is an argument against steel frame constructions, although usually, the time savings outweigh any adjustments that need to be made on site.

Steel structure, a term often heard in the realms of construction and architecture, refers to buildings or structures that are predominantly made from steel, one of the most versatile and sustainable materials used in construction today. In this article, we will delve into the depths of understanding what steel structure really means, and explore its advantages and disadvantages in detail.

Understanding Steel Structures

When we talk about What is steel structure?, we refer to a framework that is composed entirely or largely of steel components. These structures are designed to withstand loads and stresses through a skeleton frame made up of steel beams and columns. This method of construction is widely used for large industrial buildings, skyscrapers, bridges, and increasingly for residential buildings as well.

Key Components of Steel Structures

1. Steel Beams: These are horizontal components that bear loads from the floors and roofing.
2. Steel Columns: Vertical members which transfer the load to the foundations.
3. Steel Trusses: Triangular units used for supporting roofs and bridges.
4. Connectors and Fasteners: These include bolts and welds that hold the structure together.

Advantages of Steel Structures

Steel structures boast several benefits that make them a preferred choice in many construction projects:

Durability and Strength

Steel is renowned for its strength and durability. It can withstand extreme weather conditions like storms, heavy snow, and even earthquakes, making it a reliable choice for any construction project.

Flexibility and Adaptability

One of the most significant advantages of steel structures is their flexibility. They can be easily modified, extended, or adapted to suit changing needs or functions.

Cost-Effective

Despite the upfront costs, steel structures can be more economical in the long run. They require less maintenance and are more durable compared to traditional construction materials.

Eco-Friendly

Steel is one of the most recyclable materials in the world. The ability to recycle and reuse steel helps in reducing environmental impact, making steel structures a sustainable choice.

Speed of Construction

Steel structures can be pre-fabricated, which significantly speeds up the construction process. This is particularly beneficial in reducing labor costs and in projects with tight deadlines.

Disadvantages of Steel Structures

While there are numerous benefits, there are also some drawbacks to using steel in construction:

Corrosion

The most significant disadvantage of steel structures is their vulnerability to corrosion, especially in humid or marine environments. Regular maintenance and protective coatings are required to mitigate this issue.

Conductivity

Steel is a good conductor of heat, making steel buildings potentially more challenging to insulate against heat and cold.

Fire Resistance

In high temperatures, steel loses its strength. Fireproofing measures are essential to ensure the safety and integrity of steel structures in case of a fire.

Cost

The initial cost of materials for steel structures can be higher than those for traditional construction materials. However, it's important to consider the long-term savings in terms of maintenance and durability.

Conclusion

Understanding what is steel structure? involves recognizing both its strengths and weaknesses. The use of steel in construction offers numerous advantages such as durability, flexibility, and eco-friendliness, but it also comes with challenges like corrosion and higher initial costs. However, with advancements in technology and materials science, many of these disadvantages are being effectively addressed, making steel structures an increasingly popular choice in modern construction.
