Indiana continues to be an early mover into new verticals and anticipating the growing demand for shop fabricated structural steel over site fabricated structural steel, Indiana set up a state of the art fabrication facility in Jejuri, near Pune.
The advantages of shop fabrication over site fabrication are excellent welding quality, dimensional accuracy, faster delivery in volumes and long lasting paint finish.
In our endeavor to establish a world class facility, Indiana has commissioned a new "CNC BEAM AND PLATE PROCESSING LINE" imported from USA. It consists of a fully automatic band saw machine, plate processors and beam drilling machines.

Advantages of Using CNC Machines In Structural Fabrication Work
|Manual Work||Work using CNC Machines|
|Manual layout required to cut the beam or to drill all holes||Auto measurement is done and cutting and drilling operation is automatic, 70-80 % cycle time can be saved|
|Cutting quality is not satisfactory and one more operation of grinding is required||Smooth finish is obtained since grinding is avoided and accuracy is achieved upto 0.1mm|
|Since the operation involves manual materials handling for cutting and drilling, the turning of the beams occurs at least 3 to 5 times, leading to chances of handling damages and accidents.||No material handling is involved since cutting and drilling of holes takes place for all the sides of sections with the beam in one position.|
|Time taken to drill 100 holes of dia 22 mm in one beam of size 500x300x25x15x9000 mm long is approximately 400-420 min with a good fitter and cutter||Time taken by CNC is approximately 30 minutes|
|Manpower required for material handling is more hence the man-hour spent per hour will be more||Only two machine operators (For cutting and for drilling machines ) required to perform entire operation and hence less man – hour per ton|
|Chances of human error are more as the drawings have o be referred to on the shop floor||Since CNC files are downloaded directly from the drawing software, chances of errors are almost negligible|
|Chances of human error are more as the drawings have o be referred to on the shop floor||Since CNC files are downloaded directly from the drawing software, chances of errors are almost negligible.|
|When percentage of components is high in structures, time taken to prepare is long resulting in delay in fabrication||When the percentage of components is high, mass production is possible which helps in cutting down the cycle time for fabrication.|
