The plant comprises bar drawing, wire drawing, wire finishing and straightening, bar turning, precision grinding and cold rolling departments. There are also a tool and die making plant, a test house and a joiner's shop for the preparation of packing cases for export orders.

The raw steel for the commercial qualities of bars has an initial ultimate tensile strength of 28 to 32 tons per square inch which becomes increased when drawn to 37/40 tons per square inch according to the section and the amount of drawing to which it is subjected.

Among the principal customers are: railways, the Admiralty, the War Office, the Air Ministry and motor manufacturers. A stock of over 1,000 tons of various finished products is always maintained for the purpose of meeting urgent orders.

The bar drawing installation comprises cold and hot bar pointing machines, pickling, neutralising and cleansing baths, seven draw benches of various capacities, three reeling and polishing machines, special polishing machines, a roller straightening machine for sections other than rounds, a double sided ram type straightening machine, and special cutting-off machines having a limit of accuracy for the lengths of the bars ofplus or minus one ten-thousandth of an inch.
