A steel truss is a structural framework that was designed to support loads by efficiently distributing forces along other materials. It consists of straight materials that are connected at the joints to form a series of triangles and other geometric configurations. Steel trusses are used in different industries, mainly construction, for various purposes like providing strength and stability for structures. Additionally, steel trusses could also add flexibility in designing large-span structures such as bridges, roofs, and industrial buildings.

Advantages of Steel Truss
Strength and Durability – Steel trusses are known for their high strength and durability, providing excellent structural integrity and making them suitable for supporting heavy loads and ensuring the longevity of the structure.
Large Span Capability – Steel trusses are well-suited for large-span structures as they can be used even in expansive and open interior spaces without the need for additional support columns or walls.
Efficient Load Distribution – The geometric design of steel trusses, often in triangular shapes, enables efficient distribution of loads along the other parts. This contributes to the stability and load-bearing capacity of various projects.
Disadvantages of Steel Truss
Cost – The initial cost of steel trusses, including materials and fabrication, can be higher when you compare them to some alternative materials. However, this cost may be offset by factors such as durability and longevity.
Weight – Steel trusses can be relatively heavy and could require careful consideration in design and construction. The weight of steel trusses could also impact transportation costs and foundation requirements.
Thermal Conductivity – Steel is known as a good heat conductor, thus steel trusses have higher thermal conductivity when you compare them to their alternative counterparts.
Complex – The design and engineering of steel trusses can rather be complex, especially for large and unique structures. The complexity of steel trusses’ design could require skilled professionals to ensure proper details and calculations.
Limited Use in Certain Environments – Steel trusses are not suitable for environments with high levels of humidity or corrosive chemicals. In such cases, alternative materials with better corrosion resistance are recommended rather than steel trusses.
