Reinforced concrete is one of the most important building materials in the world today. It is the first choice for any construction requiring tensile strength. The reinforcing steel used comes in the form of rebar, reinforcing mesh, lattice girders or reinforcing wire. On average, BDW supplies more than half a million metric tons of such steel products every year. It manufactures top-quality products with the latest production technology while meeting the highest occupational safety and environmental protection standards. With certified quality, environmental protection and energy management procedures, BDW makes sure it always meets both its customers’ needs and all the regulatory requirements. The heart of the production process for many different reinforcement products, many of them customized, is always steel wires between 4 and 25 millimeters thick. To create the reinforcement products by bending and joining the wires, the wires first need to be unwound from coils; only then can the straightening, bending and cutting equipment do its work. The coils weigh tons, and care is required when unwinding them – the unwinding process needs to counteract the curve in the wire that the winding caused. In this straightening process, the torsion of the steel, the twisting in the longitudinal direction, plays an important role. This must not be too high for further processing.
