Steel buildings are renowned for their strength, durability, and versatility, making them an ideal choice for a wide range of construction projects, including warehouses, commercial spaces, agricultural buildings, and more. While the primary structure of a steel building plays a crucial role in supporting its load, the secondary frames are equally important in providing additional support and stability.
In this article, we will explore the role of secondary frames in steel buildings, their components, and why they are essential for the overall structure’s integrity.
Before diving into the details of secondary frames, it’s important to understand the basic structure of a steel building, which is divided into two main categories: primary frames and secondary frames.
Primary Frames: These are the primary structural elements of a steel building, including columns, main beams, and braces, which are responsible for carrying the majority of the load. They are designed to handle heavy loads and provide the foundation for the building's structural integrity.
Secondary Frames: These components provide additional support to the primary frame and contribute to the overall stability of the building. Secondary frames help distribute loads more evenly and ensure the building can withstand external forces, such as wind and snow. They are typically lighter and more flexible than primary frames but are still crucial to the building’s strength and durability.
Secondary frames are a set of structural components used to support the roof and walls of a steel building. These frames are designed to work in conjunction with the primary framing system, ensuring that the load from the roof, walls, and other elements is distributed evenly across the entire structure.
Purlins: Purlins are horizontal beams that run perpendicular to the main steel beams (primary frames) and support the roof panels. They are essential for distributing the weight of the roof and ensuring the roof is properly supported. Purlins are typically made of steel and come in different shapes, such as C-channel or Z-purlins, depending on the specific design and load requirements.
Girts: Similar to purlins, girts are horizontal structural members that run along the walls of the steel building. They are used to support the wall panels, ensuring they stay securely attached to the frame. Girts help distribute the weight of the wall panels evenly and are often made from steel or other strong materials.
Bracing: Bracing is used to add lateral stability to the building. Braces are typically placed diagonally across the building to resist forces such as wind and seismic activity. These braces prevent the building from swaying or shifting during high winds or other external pressures.
Eave Struts: Eave struts are located at the intersection of the roof and the walls. They provide additional support to the roof and help transfer the loads from the roof panels to the rest of the building structure.
Base Angles: Base angles are used to connect the foundation to the steel framing system. They help secure the steel building to its foundation and prevent movement.
Ridge Beams: Ridge beams are used at the peak of the roof to support the ridge plate, which helps hold the roof in place. These beams are critical for ensuring that the roof stays level and secure.
One of the primary functions of secondary frames is to distribute loads evenly throughout the structure. While the primary frames handle the bulk of the load, secondary frames help spread the weight from the roof, walls, and other elements across the building. This ensures that the building maintains its structural integrity and prevents localized failures.
Secondary frames help provide lateral stability to the building, preventing it from shifting or swaying due to external forces such as wind, seismic activity, or snow loads. The bracing, girts, and eave struts are all part of the secondary frame system that ensures the building can withstand these forces and remain stable over time.
Secondary frames are essential for supporting the roof and wall panels. Purlins and girts work in tandem to hold the roof and walls in place while distributing the load across the structure. This is especially important for larger buildings with expansive roofs or walls, where the panels need additional support to prevent sagging or buckling.
One of the benefits of secondary frames is that they are typically made from lighter materials than primary frames, which makes them more flexible and cost-effective. The use of secondary frames reduces the overall cost of the building, as they are designed to be both strong and lightweight. This flexibility also allows for easier customization of the building’s design and layout.
Secondary frames play a crucial role in enhancing the performance and longevity of steel buildings. Here are some of the key reasons why secondary frames are indispensable:
Secondary frames help ensure that the building can handle both vertical and horizontal loads, contributing to the overall strength and stability of the structure. Without secondary frames, a steel building would lack the necessary support to maintain its shape and functionality under external pressures.
By distributing loads efficiently, secondary frames allow for the use of lighter materials without compromising the building’s performance. This reduces the amount of steel required for construction, which in turn lowers the overall material costs.
Secondary frames offer increased versatility in the design and layout of the building. For example, they can be used to create clear-span spaces (areas without interior columns), which is especially useful for warehouses, manufacturing facilities, and other large spaces. The flexibility of secondary frames allows for greater design freedom and customization.
The stability and support provided by secondary frames help increase the lifespan of the building. By preventing structural movement or distortion, secondary frames contribute to the building’s durability and ensure it can withstand the test of time, even under harsh weather conditions.

At the heart of every steel building is the steel structure, which plays a pivotal role in ensuring the building’s overall performance and longevity. A steel structure comprises both primary and secondary framing components, working together to provide a robust and efficient system that supports the entire building. The primary frames—composed of columns, beams, and braces—carry the majority of the load, while the secondary frames enhance the building's stability, helping to distribute weight more evenly and providing support for the roof and walls.
The key benefit of a steel structure lies in its ability to withstand the harshest conditions, such as high winds, snow loads, and seismic activity. Unlike wood or concrete, steel is impervious to common problems such as decay, pests, and fire, offering long-term durability with minimal maintenance. This is why steel structures are ideal for buildings that require a high degree of resilience and long-term performance.
Additionally, a steel structure offers design flexibility. It allows for expansive, open spaces without the need for internal columns, making it an excellent choice for large commercial buildings or warehouses that require clear spans. The customizable nature of steel structures means they can be adapted to meet the specific needs of any project, whether it's residential, industrial, or commercial.
Incorporating a steel structure into your building design ensures a strong, efficient, and sustainable foundation, ultimately reducing long-term maintenance costs and improving the overall lifespan of your building. Whether you’re building a warehouse, factory, or office space, a steel structure is an investment in the building’s strength, safety, and durability.
Primary frames are the main structural components that bear the majority of the load, such as columns, beams, and braces. Secondary frames, on the other hand, provide additional support and stability, helping to distribute loads and support the roof and wall panels.
