Weight Reduction: The hollow interior of these sections allows for a high strength-to-weight ratio. This means they can provide substantial structural support while keeping the overall weight of the structure relatively low. This is particularly valuable in applications where reducing dead weight is important, such as in aerospace and automotive engineering.

Fire Resistance: In some cases, hollow sections can be filled with fire-resistant materials to improve fire resistance in buildings and structures.

Durability: Depending on the material used, hollow sections can provide a long service life with minimal maintenance, making them cost-effective in the long run.
