Macalloy formally McCalls Special Products has come along way since 1921 when the company was first founded by three men, T H McCall, E L Raworth and C W Hamilton. McCalls in the early years supplied the rapidly expanding reinforced concrete trade with steel rods and bars.
In the decades that followed, McCalls developed services in cutting bars to length, bending, straightening and designing reinforced bar products for concrete structures.
In the post war era of the 1940’s McCall’s invested considerably in the development of plant and building facilities, which as a result developed the first post tensioning system in 1948. The Macalloy system was an instant success when it was launched, and became a by-word for post tensioning in the construction industry.
In 1962 the company became a totally-owned subsidiary of the United Steel companies was nationalized and became part of the British Steel Corporation and McCalls became part of Reinforcement Steel Services.
In the 1980`s, Sir Norman Foster designed the Renault distribution centre in Swindon, England using Macalloy’s Tension Structure system. The building went on to win numerous international awards and this unique application began a trend in wide span structural design. Leading to new systems and technology that were to change traditional principles forever.
In 1983 the company become part of allied steel and wire plc, then a further two changes of ownership took place in the 90's. But the final change of ownership was in August 2003 when the directors of the business carried out a successful management buy out with the support of UK enterprise.
