DWK Drahtwerk Koln GmbH, a subsidiary of Saarstahl AG, has expanded its long-standing cooperation with Max Bogl Wind AG, strengthening the supply of prestressing steel wire for hybrid wind tower construction.
Under the new agreement, both companies will increase delivery and purchase volumes of high-quality prestressing steel wire for Max Bogl’s hybrid towers, extending their strategic partnership for the coming years. The collaboration, which began in 2015, secures long-term supply of critical wire products used to stabilize concrete tower segments in modern wind power installations.
Prestressing steel wire plays a vital role in ensuring tower durability and structural performance by placing concrete elements under compressive stress to withstand turbine loads. As Max Bogl moves toward taller hybrid towers, demand for prestressing wire is expected to grow, with up to 200 kilometres of wire required per tower.
Max Bogl highlighted the importance of reliable industrial partners to ensure quality, delivery security, and technological progress in wind tower construction. The expanded cooperation provides both parties with greater planning certainty and supports future investments in production capacity.
DWK Drahtwerk Koln manufactures a wide range of technically advanced wire products, including prestressing steel strands, wire and bars, spring steel wire, rope and profile wire, cable armouring and covering wire, and reinforcement wire, in diameters from 0.48 mm to 22.0 mm. Its products are primarily made from medium- and high-carbon steels, micro-alloyed steels, and SiCr- and SiCrV-based heat-treatable steels.
