steelbars

Steel bars, also known as rebar, are essential components in reinforced concrete construction. They are typically made from carbon steel and are characterized by their ribbed surface, which enhances their bond with concrete. This bonding is crucial for creating composite structures that can withstand tensile forces. Without steel reinforcement, concrete would be brittle and prone to cracking under tension.

The manufacturing process for steel bars involves rolling hot steel billets into long rods. These rods are then cooled and cut to specific lengths. Various types of steel bars exist, differentiated by their grade, which indicates their yield strength. Higher grades offer greater strength. The ribbed pattern, known as deformation, is achieved during the rolling process and comes in various configurations depending on the intended application and regional standards.

Steel bars are used in a wide array of construction projects, including buildings, bridges, roads, and dams. They are placed within concrete formwork before the concrete is poured. The steel carries the tensile loads, while the concrete resists compressive forces, resulting in a strong and durable composite material. The selection of the appropriate steel bar grade and size is determined by structural engineers based on the anticipated loads and design requirements of the project.
