Hot rolled coils
Hot rolled coils is produced via continuous casting process of slabs. This is the base material for cold rolled coil and coated coil, but can be also used directly into industrial applications such as steel tubes, construction, shipbuilding, gas containers, pressure vessels and energy pipelines.
Cold rolled coils
Cold rolled coils have received an additional treatment after it has been hot rolled, pickled and oiled. The coils are moved into a series of rollers to lower its thicknesses and to have uniform surface smoothness. The process is done at room temperature.
Cold rolled coils can then be further annealed to soften the steel. These characteristics, depending on the end-use, change with the intensity of the annealing.
Blackplate is the basic component of tinplate (E.T.P.) and Tin Free Steel (T.F.S.). We offer blackplate coils in soft and hard tempers.
Thanks to its interesting set of properties E.T.P. or Electrolytic Tinplate is an excellent packaging material. We offer fully assorted and unasserted E.T.P. sheets as well as cut to length sheets and coils. The tinplate products are available in prime, overrolling or secondary quality.
Hot dip galvanized coils (G.I. coils)
Passing cold rolled coil through a melted zinc bath, in order tot coat the steel with a thin layer of zinc to provide corrosion resistance, is called hot dip galvanizing.
Hot dip galvanized coils (GI coils) have many applications in construction/building, roofing, automotive parts, sections etcetera.
Pre-painted Galvanized steel is a Galvanized steel with a number of paint layers and treatments in a carefully controlled environment in a continuous coil coating line.
Pre-painting can also be done on electrogalvanized coils and cold rolled coils depending on the end-use and application of the steel.
