Specialty Steel

Tin Plate(Electrolytic Tin Plate, Tin Free Steel)
tin plate (TP) products are made by coating tin using electrolysis on the surface of thin cold-rolled steel sheet (black plates), with a thickn ess of 0.14~0.6 mm. Its shiny surface finish, superb corrosion resistance and formability make tin plates an ideal choice for the food industry and industrial parts producers. Our tin free steel sheet (ECCS), which we also produce using our new "2-step" method is widely accepted as a more economical substitute for the tin coated steel. Our TP/TFS products are widely used in the production of 3-piece and 2-piece (D&I, DRD) cans as well as can lids and bottoms. Our products serve a variety of purposes, including material for steel EOE, toys, and electronic parts.

Special Applications

  • DR TP & TFS
    • DR, which is the base material for making DR.-TP. and DR-TFS, is produced by re-rolling, using the double cold reduction (DCR) process (10~45%) after annealing. Higher levels of rigidity and strength of the DR-TP/TFS than general SR enable the thinner DR-TP/TFS to display an identical level of durability to the SR. Can producers seeking less weight and cost effective material heavily favor DR-TP/TFS.
  • Ultra-thin TFS
    • TFS is a favored choice for makers of steel-copolymer tapes because of the high heat tolerance and superior formability of the extra-thin gauge (0.15 mm thickness). While mainly used as material for optical cables, it has recently experienced a remarkable growth rate of 30% due to the explosive use of cellular phones and high-speed communications networks built nation-wide.
  • Extra Wide TP/TFS
    • Answering the demand of can production companies for enhanced productivity, steelmakers with advanced technology have started producing extra-wide tin plates and tin free steel plates (TP/TFS).
