The Kley France story started 60 years ago, with the invention of a patented wire rope socketing technique (anchorage).
This technique now has many civil engineering applications, such as pre-stressed concrete and suspended roofs, requiring the tensioning of anchoraged wires and wire ropes. Historic Kley France projects with this technology include Saint-Nazaire Stadium in the 60’s, Munich Stadium in 1972, and Teheran Stadium in 1977.
