Mergers and takeovers characterize the painting industry in the 1960s and substantially shaped the competitive landscape. To consolidate its own market position, Walther opens a second production site in Neunkirchen-Struthütten in 1961, where pressure tank construction and large-scale production of ventilation systems, standard boxes, and coating lines are realized. This decision is closely related to the flourishing metal industry in Siegerland, which is still considered an outstanding center for metal processing to this day. The choice of this location therefore represents a coherent entrepreneurial approach in which Walther benefits from both the existing expertise as well as the infrastructure of the region and thus becomes the market leader in the field of tank manufacturing.
To complement the portfolio, the company adopts the "Airless Paint Spraying" technology, developed in the USA. This new technology is particularly advantageous for processing large, contiguous surfaces.
