Rebar fabrication process

The fabrication of reinforcing steels into shapes suitable for fixing into concrete formwork is normally performed in advanced countries by specialist reinforcement fabrication centres. In these advanced countries very little reinforcement is cut and bent on-site. In India, the reinforcement bar fabrication is predominantly done at site by employing huge labour force and semi-automatic machines. Although the cutting and bending of steel reinforcement appears relatively straightforward, the steel reinforcement fabrication service centres are well equipped to do so in a consistently accurate manner. The service centres works under defined set of quality management criteria to ensure the accuracy of cutting and bending operations in order to achieve proper fit at site, and to maintain the required technical parameters defined by the clients.

Rebar Processing
The basic fabrication processes consist of cutting and bending the reinforcement steel. The actual process employed depends on the material being processed, whether bar or coil. At the Rebar processing centre coated or bare reinforcement are fabricated by cutting on shear lines, and thereafter bending on power bending machines. The processing ranges of these machines are from 16 mm diameter to 50 mm diameter. The reinforcement bar, in coil form, is obtained from the mills in Coil form in the size range of 6mm to 12mm and is bent to stirrups and most complicated shapes through the Automatic Link Bending machine to promise the delivery of dimensionally accurate stirrups and complex shapes just in time (JIT delivery).
