Short Description:

We are looking for solutions to quantify the ‘glossy/shiny appearance’ of the wire bundle

Challenge Details

Galvanization is the process of applying a protective zinc coating to steel, to prevent rusting. The most common method of galvanization is hot-dip galvanizing, in which the wires are submerged in a bath of molten hot zinc. We have a continuous hot-dip galvanization setup for producing galvanized (GI) wires, which also imparts a glossy appearance to them. ‘Extent of gloss or shiny appearance’ is one of the parameters used to make a perceptible difference in the quality of GI wires.

We want a solution that will help quantify the ‘glossy/shiny appearance’ of the wire bundle so as to compare it with another bundle, which may or may not be lying next to it. The solution may quantify (or at least rank) the ‘glossy/shiny appearance’ of various bundles, which may be lying in different light/ambient conditions. Wire size in the bundle may vary from 0.9 mm to 6 mm. The dimension of a typical bundle (diameter X Height) is ~3 ft. * 4 ft.

We are not looking for a solution to determine the ‘glossy/shiny appearance’ of a specific point on the wire.  




  • The diameters of the wires range from 1.6 mm to 4.88 mm.
  • The zinc coating thickness varies from 50 gsm - 300 gsm, i.e. 7 microns to 50 microns.
