Steel reinforcement is a material used to reinforce and strengthen concrete, eliminating some of the structural vulnerabilities of traditional concrete construction. By adding steel reinforcement in concrete, many concrete structures are able to stand up to unprecedented levels of stress and pressure, allowing them to last significantly longer than structures not reinforced with steel. Metal reinforcements for concrete come in a variety of sizes and shapes. The three most common types of steel reinforcement are bar steel, coil steel, and welded wire fabric (WWF). Reinforcing bars are rods of steel that are placed in concrete columns, beams, and walls to increase the load-bearing capacity of the structure. These bars, commonly referred to as “rebar,” come in a variety of shapes and sizes and can be cut to fit specific sections of a structure. Coiled steel reinforcement is flat steel that is wound into coils and used to increase the strength of concrete structures. This type of metal reinforcement is usually supplied in the form of thin sheets of steel that are pre-formed into coils. Welded Wire Fabric (WWF) is a composite of wire that is welded together to form a planar reinforcement layer. This reinforcing material is much thinner than rebar and is used in applications that require a supportive surface or layer, such as floor slabs or pre-cast panels. There are several types of WWF, and each type offers a different level of strength and support. All types of steel reinforcement for concrete are held in place with metal clamps, ties, or clips. These fixtures come in a variety of sizes and styles and can be permanently secured to the concrete structure. The metal clamps, ties, and clips are attached to the mesh before the concrete is poured, creating an interlocking connection between the steel reinforcement and the concrete structure. Once hardened, steel reinforcements significantly enhance the overall strength of a concrete structure. The added strength makes it possible to build larger and more complex structures than would otherwise be possible. Additionally, metal reinforcement eliminates or reduces cracking due to normal structural movement or seismic activity.
Steel reinforcement is an essential material for any structure that is built with concrete. It increases the structural strength of the project, reduces the chance of cracking, and helps the structure last longer. By selecting the appropriate type of steel reinforcement and attaching it to the concrete structure before the concrete is poured, it is possible to build a project that will stand up to even the most extreme pressure and weather conditions.
