Quality Assurance


We always strive to provide the best quality products to our esteemed clients. We have chalked out a quality assurance plan, which is given below:-

Quality Assurance Plan

1). Checking of Basic Raw materials & components.

  • Sheet Steel- For size & surface finish.
  • Electrical Stampings - check for surface finish, weight, size, cut edge, orientation direction for CRGO steel. Thickness-must be burr free, smooth.
  • Structural steel- For hardness, thickness and edge finish, size &straightness, rustfree. Hardware to be checked for size & finish of plating.


2) Copper Conductor­

  • Bar-Strips-softness, size, weight, straightness & conductivity-check resistance per meter &verify for electrolytic grade, edge should be burr free. Manufacturers test certificate.
  • Enamelled or DGC conductor-Size of bare conductor, thickness &quality of insulation, weight, softness (wind ability), continuity, conductivity, Res per meter & velocity for electrolytic grade. Manufacturers test certificate.
  • Insulating materials-Quality, thickness & size of material finish & conduct high voltage break down test on sample pieces, insulated PVC or other wires for voltage grade, size &ISI mark. Manufacturers test certificate.
  • Bought out standard components-rating & make finish & manual & electrical operation on no load contact make & break by multimeters.
  • Insulating varnish & paint-make, packing & date of expiry check proper flow & viscosity when using proper thinner. Use stoving temperature only as per manufacturers’ instruction.


Quality Cheek During Mfg. Process

  • During Fabrication - Proceed as per approval drawing finish of bends & welding to be smooth & burr free. Use hand tools & machines with dies with care and proper tooling, final assembly to be matched with drawing.
  • Cheek chemical properties of solution of various tanks raise temperatures as required. Strictly follow the surface treatment procedure 7 tank namely degreasing, rinsing, Picklingrinshing, phosphatising, rinsing and passivating final surface finish to be lustrous Grey.
  • Raise temperature of stoving oven to above 1800C. Spray the powder of specified shade.


Cure the job sprayed with powder for 10 minutes at 1800C.

Quality Check For Testing Equipment

  • Equipments are calibrated once in a year from Govt. Lab (Govt. Engg. College)
  • Testing equipments are kept in proper packing/condition to ensure accurate result while testing.
