What structural steel component does the designation "VL" refer to?

The designation "VL" typically refers to a type of metal decking, which is used in construction for floor and roof systems. Metal decking serves as a base for concrete or is used as a roofing material, providing structural support and facilitating the construction process. This type of decking comes in various configurations and is essential for creating safe and durable surfaces in buildings.

Hollow sections, flanged beams, and structural angles are different components with distinct applications and identifiers, which are not related to the "VL" designation. Hollow sections are usually used for structural frameworks, flanged beams (commonly referred to as wide flange beams) are structural elements in construction that resist bending, and structural angles are L-shaped components primarily used for bracing and framing. While all these components are critical in steel construction, they do not align with the designation "VL" that specifically points to metal decking.
