(1). Mild steel: Mild steel is a type of low-carbon steel that is commonly used in the construction industry. It is known for its malleability and easy to shape, but it has a low tensile strength and ductility. This type of steel is used for non-critical and non-load bearing members.
(2). HYSD bars: HYSD (High Yield Strength Deformed) bars are a type of steel bars that are made by cold twisting and deforming the steel. They have a high yield strength and are used for reinforcement in construction. They are known for their high strength and corrosion resistance, but they have low ductility.
(3). CTD bars: CTD (Cold Twisted Deformed) bars are a type of steel bars that are made by cold twisting and deforming the steel. They have a high yield strength and are used for reinforcement in construction. They have high strength and ductility which makes them suitable for use in seismic-prone areas.
