Green steel rebars (steel proceeding from an electric arc furnace using 100% renewable energy)

Steel reinforcement rebars are used to improve the tensile strength of the concrete, since concrete is very weak in tension, but is strong in compression. Steel rebars are also used because elongation of steel due to high temperatures (thermal expansion coefficient) nearly equals to that of concrete.

Welded fabric is a joined grid consisting of a series of parallel longitudinal steel wires with accurate spacing welded to cross wires at the required spacing, while welded reinforcement steel is steel bars cut, bended and welded together to satisfy required parameters.

The purpose of reinforcement is to provide additional strength for concrete where it is needed. Steel is ideal for reinforcement in concrete, as it bods well with the concrete mixture, and can be manipulated (cut and bend) to fit any concrete shape. Steel adds a tensile strength to the concrete structure, so that the structure is not as affected by tensile stresses. Welded mesh reinforcing sheets are the most used form of reinforcing in concrete and is particularly suited for flat slab construction and concrete surface beds. Other design applications of welded reinforcement steel would be retaining walls, shear walls, beams, and columns.
