How a rate is built
  • Black ₹/mtr = (base rate + freight + size premium) ÷ Mtrs/Ton
  • GI SS = Black + zinc cost ₹/mtr
  • GI SWS / GI PE = 2% / 3% below GI SS
  • Size premiums = +₹1,000/MT on 15 & 20 mm · +₹3,000/MT on 300 mm
  • Example — 15 mm B1 at base ₹61,000: (61,000 + 0 freight + 1,000) ÷ 952 Mtrs/Ton = ₹65.13
  • Premiums, discounts and GST are adjustable in Settings.
Editable in the table
  • Thickness — type any wall; that row recalculates as Mtrs/Ton = 1000 ÷ ((OD − t) × t × 0.02466)
  • Zinc cost — edit any row and the whole size updates everywhere
  • After an edit, a reset link appears above the table.
Data source
  • PARTA rate chart dt. 02.06.2026 (93 rows embedded)
