Dexion is a company name and brand particularly associated with the development of the "Dexion" slotted angle steel strip construction system, widely used since the 1950s for domestic and commercial shelving, storage racking, exhibition stands and accommodation purposes. The original UK-based Dexion Ltd manufacturing company spawned several subsidiaries before eventually ceasing trading in 2003. Its bankruptcy saw the start of a long-running pension dispute with former workers.
