As an AI language model, I don't have access to specific architectural designs and/or floor plans, so I can't say for sure what types of bars are used in duplex villas. However, based on general knowledge, below are some of the commonly used types of bars in construction:
1. Reinforcement Bars (Rebars): These are commonly used in the foundation, beams, columns, and slabs to provide structural support and stability.
2. TMT Bars: Thermomechanically Treated (TMT) bars are widely used in reinforced concrete structures due to their superior properties such as high strength, ductility, and resistance to corrosion.
3. Stainless Steel Bars: These are highly resistant to corrosion and are used in areas where corrosion is a concern, such as coastal regions.
4. Hollow Bars: These are used in areas where space is a concern, such as when constructing reinforced concrete walls.
5. Flat Bars: These are typically used for door frames, window frames, and other non-structural members.
Again, the types of bars used in construction can vary depending on project requirements, location, and other factors.
