Exploring Common Types of Steel Structures
Steel structures are integral to modern construction, offering unparalleled strength, versatility, and efficiency. From towering skyscrapers to vast industrial facilities, steel plays a key role in creating structures that meet a wide range of needs. Let’s take a closer look at the most common types of steel structures, their uses, and their unique advantages.
1. Conventional Steel Frame Structures
Description:
Conventional steel frame structures are made up of a series of steel beams and columns that form a skeleton or framework. This type of structure provides excellent support for various types of buildings and is highly adaptable to different architectural designs.
Where It’s Used:
•High-rise buildings
•Office complexes
•Warehouses
•Industrial plants
Key Benefits:
•High durability and resistance to extreme conditions
•Excellent design flexibility
•Rapid construction time
•Strength that supports heavy loads
2. Pre-Engineered Buildings (PEB)
Description:
Pre-engineered steel buildings (PEBs) are designed and fabricated in a factory before being transported to the site for assembly. This streamlined process ensures quick construction and is cost-effective, making it ideal for projects that need to balance time and budget.
Where It’s Used:
•Factories and industrial warehouses
•Commercial retail outlets
•Hangars and sports facilities
•Modular housing
Key Benefits:
•Quick assembly on-site
•Lower cost compared to conventional construction
•Customisable designs for specific needs
•Minimal maintenance required
3. Steel Truss Structures
Description:
Steel truss structures are built from triangular units connected at their joints, efficiently distributing weight and tension across the entire framework. These are often used for structures that require large open spans without internal columns or supports.
Where It’s Used:
•Roof systems for stadiums, arenas, and auditoriums
•Large bridges
•Towers and domes
Key Benefits:
•Can span long distances without needing internal support
•Lightweight yet extremely strong
•Cost-effective due to reduced material use
•Flexible design options
4. Steel Arch Structures
Description:
Steel arch structures rely on a curved shape to bear loads, distributing forces efficiently. These structures are commonly used for applications that require large, open spans with minimal supports.
Where It’s Used:
•Bridges and overpasses
•Tunnels
•Large stadiums and exhibition halls
Key Benefits:
•High resistance to compressive forces
•Aesthetic appeal for large architectural projects
•Able to cover wide spans without support

5. Portal Frame Structures
Description:
Portal frame structures are simple yet robust steel frames commonly used for low-rise buildings that require wide internal spaces, such as factories and barns. They consist of vertical steel columns and horizontal beams, creating a wide, open interior.
Where It’s Used:
•Agricultural sheds
•Warehouses
•Commercial units
•Garages
Key Benefits:
•Large open spaces without internal columns
•Economical and quick to construct
•Suitable for a wide variety of building applications
•Low maintenance over time
6. Space Frame Structures
Description:
Space frames are three-dimensional frameworks composed of interconnected steel members arranged in a geometric grid. This type of structure is lightweight but extremely strong, making it suitable for covering large areas with minimal support.
Where It’s Used:
•Airports and terminals
•Sports arenas
•Public exhibition halls
•Large atriums
Key Benefits:
•Strong and lightweight
•Allows for long, uninterrupted spans
•Good resistance to dynamic loads (such as earthquakes and winds)
•Highly customisable for complex architectural designs
7. Lattice Tower Structures
Description:
Lattice towers are tall steel structures formed by a crisscross pattern of steel members. These structures are lightweight but strong, making them ideal for industrial uses where height is essential, such as telecommunications or power transmission.
Where It’s Used:
•Transmission towers for electricity
•Communication towers
•Radio masts
•Wind turbines
Key Benefits:
•Lightweight but highly durable
•Resistant to wind and seismic loads
•Efficient use of materials
•Relatively easy and cost-effective to build
