here are some general Vastu guidelines that might apply:
Metal: The use of metal studs for framing is common in modern construction. In Vastu, metals like iron, steel, or aluminum are associated with the element of Vayu (Air) and are often used in the north, east, or northwest zones of a building, as they correspond to these elements.
Wood: Wooden studs or framing elements represent the element of Vastu Purusha (earth) and are ideal for supporting structures in areas governed by earth, like the southwest or center of the building.
Southwest Direction: According to Vastu, the southwest is the zone of strength and stability. It's ideal for placing important structural elements, such as vertical studs or posts, which offer stability and balance to the building.
East and North: For doors, windows, and ventilation, elements like studs (or any construction materials) should align with the principles of maximizing natural light and air. These directions should not be blocked or overly crowded with heavy materials or thick walls that restrict the flow of energy.
