Due to its superior performance and low price, steel is widely used in the construction industry. Steel structures are constructed to meet customer needs. This article will explore some of the most common types of steel structures currently used in prefabricated buildings.
Overview of steel structures
Steel structure is a material designed specifically for various types of steel structures, made into specific shapes. These materials meet the specified chemical composition standards and have the required strength. They are usually classified as hot-rolled and composite products, with cross-sectional shapes including angle steel, channel steel, I-shaped or H-shaped, square, rectangular, and circular. The global demand for steel structures continues to steadily increase.
Common types of steel structures
There are many types of steel structures, each designed to meet specific requirements. Here are some of the most common types of steel structures:
1. Steel frame structure
This is the most common type of steel structure, widely used in various buildings ranging from high-rise office buildings to residential buildings. The steel frame structure consists of vertical steel columns, horizontal steel beams, and steel connectors that fix the components together. Beams and columns are connected by welding or bolts to form a sturdy and stable structure.
Advantages: They are assembled quickly, reducing construction time and labor costs. Moreover, compared to concrete structures, they are lightweight and require less foundation work. In addition, steel is a sustainable and recyclable material, making it an environmentally friendly building choice.
Disadvantage: They may be more expensive than other construction methods. They require careful planning and design to ensure the integrity of the structure. If there is no proper insulation, the energy efficiency of the building will be affected.
2. Steel truss structure
Steel truss structure is a construction method that uses a series of interconnected triangles to evenly distribute the weight of the entire structure. Steel truss structures are commonly used for roofs and bridges, but can also be used for other applications that require large spans.
Advantages: They are lightweight and require less material than other types of structures, making them more cost-effective. They can also be quickly assembled, thereby reducing construction time and labor costs. The steel truss structure is also very durable and can withstand harsh environmental conditions such as strong winds and earthquakes.
Disadvantages: Their design and construction are more complex than other structures, requiring specialized knowledge and equipment. They also require careful maintenance to prevent corrosion and other types of damage over time.Once built, it becomes even more difficult to modify or expand, which limits its flexibility for future use.
3. Steel arch structure
These structures are used for bridges and buildings that require large spans. The steel arch structure is composed of curved steel arches that support the weight of the structure. An arch is composed of a series of steel components connected together, forming a curved shape.
Advantages: They can span long distances without the need for intermediate support, making them an ideal choice for bridges and other structures that require crossing obstacles such as rivers or valleys. In addition, compared to other types of structures, they are lightweight and require less material, making them more cost-effective. The steel arch structure is also very durable and can withstand harsh environmental conditions such as strong winds and earthquakes. They are also easy to maintain and repair, as the arches provide clear access space beneath the structure.
Disadvantages: Their design and construction are more complex than other structures, requiring specialized knowledge and equipment. They also require careful maintenance to prevent corrosion and other types of damage over time. Once built, it becomes even more difficult to modify or expand, which limits its flexibility for future use.
4. Steel cable structure
Steel cable structure is a construction method that uses steel cables to support the weight of the structure, forming a suspension system. They are usually used for suspension bridges and roofs. The steel cable structure consists of steel cables fixed on towers or columns at both ends of the structure. Then tighten the cable onto the span of the structure to form a suspension system that supports the weight of the structure. The cable is fixed on the ground or concrete block to provide additional stability.
Advantages: They can span long distances without intermediate support, making them an ideal choice for suspension bridges and other structures that need to cross obstacles such as rivers or valleys. They are lightweight and require less material than other types of structures, making them more cost-effective. The steel cable structure is also very durable and can withstand harsh environmental conditions. They are also easy to maintain as cables can be easily inspected and replaced if necessary.
Disadvantages: Their design and construction may be complex, requiring specialized knowledge and equipment. They need to be carefully maintained to prevent corrosion and other types of damage over time. Once the steel cable structure is built, it is difficult to modify or expand it.
5. Steel space frame structure
The steel space frame structure is a construction method that uses a three-dimensional steel pipe frame to support the weight of the structure. Steel space frame structures are commonly used in large buildings such as airports and sports stadiums. The steel space frame structure is composed of a series of steel pipes, which are welded together to form a three-dimensional frame. Then cover the frame with roof and cladding materials to form the final structure.
Advantages: They can span long distances without the need for intermediate support, making them an ideal choice for large buildings and other structures that require wide open spaces. In addition, compared to other types of structures, they are lightweight and require less material, making them more cost-effective. They are also very durable and can withstand harsh environmental conditions such as strong winds and earthquakes. They are also easy to maintain because the framework is easy to inspect and repair.
Disadvantages: Their design and construction are more complex than other structures, requiring specialized knowledge and equipment. They also require careful maintenance to prevent corrosion and other types of damage over time. Once built, it becomes even more difficult to modify or expand, which limits its flexibility for future use.
6. Light steel structure
Lightweight steel structures use lightweight steel frames to support the weight of the structure, typically used in residential and small commercial buildings. Light steel structures are composed of steel frames made of thin steel plates, which are cold-formed into C-shaped or Z-shaped sections. Then use screws or bolts to assemble these sections into a frame.
Advantages: They are assembled quickly, reducing construction time and labor costs. Moreover, compared to concrete structures, they are lightweight and require less foundation work. In addition, lightweight steel is a sustainable and recyclable material, making it an environmentally friendly building choice. They are also easy to maintain and repair, as damaged parts can be easily replaced.
Disadvantage: They may not be suitable for buildings with high loads or large spans, as thin steel frames may not provide sufficient strength. Although fire-resistant coatings and materials can be used to improve their performance, they may not be as fire-resistant as other building methods.
7. Prefabricated steel structure
Prefabricated steel structures are a construction method that uses standardized components that are prefabricated off-site and assembled on-site. Prefabricated steel structures are commonly used in industrial buildings such as factories, warehouses, and distribution centers. Prefabricated steel structures are composed of standardized components such as steel columns, beams, purlins, and wall beams, which are designed to be easy to assemble together.
Advantages: They are assembled quickly, reducing construction time and labor costs. Standardized components also make them more cost-effective than customized structures. They can be designed according to specific requirements, such as load-bearing capacity, insulation, and environmental factors. Prefabricated steel structures are also very durable and can withstand harsh environmental conditions such as strong winds, earthquakes, and fires. They are also easy to maintain as damaged parts can be easily replaced.
Disadvantage: They may not be suitable for buildings with special requirements or non-standard sizes. In addition, standardized components may limit design flexibility and customization options. Finally, prefabricated steel structures may not have the same aesthetic appeal as other construction methods.
