Structural Strength: Their unique interlocking shape allows them to be lapped (overlapped) at supports, creating a continuous beam that offers significantly higher load-bearing capacity than C-shaped sections.

Versatility: They are commonly used in industrial sheds, warehouses, and agricultural buildings.

Lightweight: Despite their strength, they are lightweight, reducing the overall weight of the building's skeleton.

Customization: Often manufactured from high-tensile galvanized steel, they can be ordered pre-cut and pre-punched for fast, bolt-together assembly on-site
