What are lightweight steel trusses primarily made from?

Lightweight steel trusses are primarily made from long steel chords and flat or tubular members because these materials provide the necessary strength and structural integrity while keeping the overall weight of the truss system low. The long steel chords serve as the main load-bearing elements, allowing for greater spans and reduced material usage. The flat or tubular members, which are often used for the webbing of the truss, contribute to its overall stability and help distribute loads evenly throughout the structure.

Using steel in the construction of trusses also offers benefits such as resistance to warping, pest damage, and fire, making it ideal for various building applications. This versatility and durability are significant advantages over other materials like wood and concrete, aluminum, or plastic composites, which do not provide the same balance of strength and lightweight properties.
