Macalloy
McCalls Special Products Ltd is a British manufacturer of steel bar and cable components for tensioned concrete, ground anchors, curtain walling, and steel structures. It operates under the Macalloy brand and claims to be a world leader in that market.

As of 2021[update], 3⁄4 of the company's products are exported.
McCall and Company Ltd was founded in 1921 by T H McCall, Edwin Llwewllyn Raworth, and C W Hamilton, on Queens Street, Sheffield to supply steel rebar for concrete contractors.
In 1927, it moved to former railway engineering sheds on Nunnery Lane for two years then again to its steel supplier, United Bar Strip Mills' Templeborough Steelworks.
In 1948, the firm began to manufacture bars for post tensioned concrete. These were used to reinforce a 500 foot (150 m) central span of the 1960 M2 Medway Bridge, then the world's widest prestressed concrete span.
McCall and Company Ltd became a subsidiary of United Steel Companies Ltd in 1962 and three years later moved to Meadowhall Road, Rotherham. In 1966, United Steel Companies Ltd was nationalised as British Steel.
Allied Steel and Wire Ltd purchased McCall and Company Ltd in 1975, relocating it to Hawke Street as McCalls Special Products Ltd.
Allied Steel and Wire Ltd failed in 2002 and in 2003, a management team led by Peter Hoy purchased the assets of McCalls Special Products Ltd. A new Company was incorporated to continue the McCalls Special Products Ltd name and trade. In 2006, the business moved to the former Dinnington Colliery.
