Meadowhall Shopping Centre built in post modern style. Construction of the shopping centre has destroyed most above ground traces of Hadfields 1897 East Hecla Works. Hadfield was prominent in the development of Alloy Steels especially Manganese Steel which was produced by the quenching in water of steel at a 1000 degrees C. This was used first in railway wheels, crossings and digging machines but with the advent of the first world war its potential for use in armour piercing shells, tank treads and helmets. Later inventions included Silicone Steel which was used in electrical transformers. (Bayliss 1995, 33) & (www.tilthammer.com/bio/hadf.html - updated 2003) On the 19th century mapping this area of the meadowhall complex was the water powered complex of Parker Wheel / aka Brightside Paper Mill (Crossley 1989, 23). This mill is first recorded in 1604 and was alternately a grinding wheel, tilt forge, paper mill, flour mill, forge (again) and rolling mill. In ruins by 1895 (ibid.) nb. The River Don was straightened at this point (around 1920) apparently to make room for expansion on the Hadfield works. The present weir in the river relates to this phase rather than the earlier mill and may have been built to provide a steady flow of water to the steelworks for industrial processes.
