Exploring The Different Types Of Steel Structures

In this article, we will explore the different types of steel structures such as portal frame steel buildings, steel truss structures, and steel grid structures. Each type has its unique characteristics and applications.

By delving into the details of these steel structures, you will gain valuable insights that can help you make informed decisions for your future construction projects.

Common Types Of Steel Structures

Portal Frame Steel Building Structures

Portal frame steel building structures offer a high load-bearing capacity, wide span, and long lifespan. They have a simple and lightweight design, making them easy to construct.

These structures use hot-rolled or welded section steel, cold-formed C/Z steel, and steel pipe.

They have a light roof and wall structure, providing flexibility and simplicity in construction. Portal frame steel building structures are known for their wide applications and are widely used in various industries. They are commonly used for industrial, commercial, agricultural, and institutional buildings.

Advantages of Portal Frame Steel Building Structures

  • Customised to meet specific project requirements
  • Versatility- suitable for many various applications
  • Quick and easy construction, saving you time and money.

Steel Grid Structure

The steel grid structure is composed of many rods. Its composition lends itself to flexibility in design and construction. With its lightweight nature and high rigidity, the steel grid structure offers a cost-effective solution for various construction projects, including, but not limited to gymnasiums, exhibition halls, and aircraft hangars.

Additionally, steel grid structures are ideal for rain roofs and canopies due to their ability to support large spans without the need for additional support columns.

Advantages of Steel Truss Structures

  • Durable, ensuring a lasting investment for your projects. 
  • Space optimisation. Steel grid structures maximise usable areas with the construction. 
  • Aesthetic versatility of steel grid structures allows for unique and visually appealing designs.

Steel Truss Structure

Steel truss structures, known for their lightweight design and high rigidity, offer a versatile solution in the construction industry. These structures consist of rods that are hinged at both ends, providing excellent load-bearing capacity.

Steel truss structures are commonly divided into plane trusses and space trusses. They're widely used in various applications such as roofs, bridges, TV towers, and marine oil platforms.

The main advantage of steel truss structures is their ability to provide larger members with smaller cross-sections, resulting in lighter weight and greater rigidity compared to solid web beams. This makes them a cost-effective choice, as they use less construction material while maintaining structural integrity.

These structures are a popular option for builders looking for efficient and durable solutions.

Advantages of Steel Truss Structures

  • Lightweight material, leading to lower costs
  • Durability can withstand harsh environmental conditions

Steel Building Frame

Steel building frames consist of beams and columns that are welded together to create a strong and rigid structure. These frames are capable of withstanding both vertical and horizontal loads, making them suitable for multi-story, high-rise, and super high-rise buildings, as well as commercial office buildings and conference centres.

Advantages of Steel Building Frame

  • Can withstand extreme weather conditions
  • Quick assembly, reducing construction time and labour costs
  • Minimal maintenance- leading to long-term savings
  • The versatility of steel frames allows for flexible design options

Advantages of Steel Construction

Cost-effective and versatile.

Steel structures are cost-effective in terms of materials and design, making them a preferred choice for many builders.

Flexibility and creativity in design.

With the ability to shape steel into various structures, builders and designers have the freedom to create unique and innovative designs.


Steel can withstand extreme forces and weather conditions, making it a resilient choice for buildings. It's resistant to rust, termites, and mould, further enhancing its durability and longevity.

Factors to Consider When Choosing a Steel Structure

When choosing a steel structure for your building project, there are several important factors to consider.

Purpose and function.

Determine whether the structure will be used for industrial, commercial, agricultural, or institutional purposes. This will help you determine the appropriate type of steel structure to choose.

Requirements of the structure.

Consider the load-bearing capacity and span requirements of the structure. Ensure that the steel structure can support the intended loads and spans without compromising its structural integrity.

Cost and ease of installation

Compare the costs of different steel structures and choose one that fits within your budget. Additionally, take into account the ongoing maintenance costs.

Environmental Factors

Factors such as wind, snow, seismic activity, and corrosion potential should be taken into account to ensure the structural integrity and longevity of the steel structure.
