History
McCalls and Company Limited was founded in 1921 by TH McCall, Edwin Llwewllyn Raworth and CW Hamilton in a stock yard on Queens Street, Sheffield. They supplied steel rods and bars which were in high demand for the expanding concrete trade. The company grew quickly and expanded into supplying straight or bent rods and bars in cut lengths.
As demand grew, the company moved to the Railway Engineering Sheds at Nunnery Lane, Sheffield.
The company connected with United Strip Bar Mills and Templeborough Rolling Mills, sourcing rods in coil. The Templeborough Mills helped finance McCalls to relocate to a new plant in 1929. This enabled the company to expand their product offering.
Over the 20 years, demand for their products increased, and in 1948 the company introduced a ‘post tension’ bar into the new ‘post tensioned’ concrete market. This was a developing trend in concrete construction and the Macalloy post tension bar was an instant success. Sales grew and in 1960, Macalloy’s prestressing bars were used exclusively in the 500ft central section of the Medway Bridge on the M2 motorway, which was at the time the world’s largest pre-stressed concrete span.
Later in 1962, the company became a subsidiary of The United Steel Companies Ltd (which in 1968 was nationalised to become British Steel). In 1965, they expanded into larger premises at the former Yorkshire Engineering Company Ltd factory at Meadowhall Road, Sheffield.
In 1975, McCalls was purchased by ASW Allied Steel and Wire Ltd. They moved again to larger facilities in Hawke Street in Sheffield, enabling them to advance and create new products including a new architectural Tension Structures range.
The company expanded into worldwide markets in the 1990s, trading as McCalls Special Products Ltd. A few years later, ASW acquired a French company, Arteon SA, which extended distribution throughout Europe.
The Asian markets began to boom and Macalloy’s post tension systems, tie bars and architectural ties were used in major, large-scale projects in Hong Kong, Malaysia, Singapore, Japan and the Philippines.
Macalloy were awarded the Queens Award for Export in 1996, in recognition of the company’s achievements. At the time, exports accounted for 65% of the company’s sales.
In 2003, the company moved back into private ownership following a MBO headed by the current Managing Director Peter Hoy, and in 2006 the company commissioned a purpose-built factory on the Old Dinnington Colliery site where it remains today.
In 2010 it was awarded The Queen's Award for Enterprise: International Trade (Export).
In 2021, Macalloy celebrated their 100th year in business by rebranding and relaunching their company website.
