Steel structure construction has introduced new possibilities for the civil and industrial construction sectors. Through this resistant and eco-friendly material, projects are completed more quickly and efficiently.
In this article, learn more about steel structures, their importance, advantages and disadvantages, and their global applications.
What is a steel structure?
A steel structure can be considered a structural element, produced exclusively from metallic materials, as its name suggests. One of the main highlights is steel, which is the primary component for all constructions adopting this standard.
Steel consists of iron-carbon alloys, where a specific carbon content is selected to determine the material’s strength level. Thus, the lower the carbon content in that structure, the lower its resistance. The same applies to the opposite situation.
Global Use of Steel Structures
Steel structures are commonly used around the world in various types of construction. The main ones include:
- Sheds and Warehouses: in this type of horizontal construction, metal offers significant advantages because it allows for large clear spans and eliminates unnecessary columns;
- Vertical Buildings: vertical projects also benefit from steel structures, as they can be built faster and are much lighter;
- Bridges: for bridges, there are several benefits, such as increased safety for workers during the construction phase and reduced assembly time.
One of the most famous constructions worldwide that utilizes steel structures is the Eiffel Tower, with its extension made of iron. The entire project took 2 years to finish, costing approximately 8 million francs to the French treasury.
Advantages of Steel Structures
There are many advantages to using steel structures in construction. However, the main ones are directly related to:
- Reduced construction time: in multi-story buildings, a 40% reduction in construction time is observed, especially when compared to concrete structures;
- Technology control: metal is produced in a steel mill, where several options can be selected, providing greater control over variations;
- Greater resistance: steel structures produce larger spans, allowing for space savings and increased strength;
- Sustainability: the material used in construction is entirely recyclable;
- Structural and service quality: in metal structures, precision is millimetric.
Disadvantages of Steel Structures
As with any other type of construction, there are some disadvantages that need to be mentioned. The initial cost is slightly higher than in other cases, requiring pre-planned initial capital. This differs from concrete structures, which are built and paid for over time.
Additionally, there are issues with corrosion, which can be easily resolved. To do so, follow recommendations, pay close attention to detailing, and eliminate any risk of corrosion from the start.
Finally, there is the issue of fire safety. Depending on the time the structure must resist high temperatures, fireproofing coatings or specific paints may be required, which can increase construction costs.
Durability
The durability of steel structures is a key point for those considering them. Thanks to mechanisms developed to reduce material deterioration, the minimum expected lifespan is 50 years, as these details are calculated during the design phase.
Curiosities about Steel Structures
One of the main facts about steel structures is how well steel fits into any type of project. Additionally, construction becomes more cost-effective and avoids waste. Finally, an essential piece of information: metal allows for the dissemination of thermo-acoustic comfort.
Steel structures are relevant for most projects, whether industrial or residential. Therefore, by planning a solid project involving them, the chances of achieving success and savings are much higher.
