Zinc galvanised coil
Hot-dip galvanised (HDG) per EN 10346 / ASTM A653
Galvanised coil is sold by gross MT but the hedgeable Zn is only 2–5% of that weight. Spreadsheet hedging of the gross tonnage would dramatically over-hedge LME Zinc (by ~30×). Metal-content derivation isolates the coating exposure for steel mills, construction buyers, and automotive OEMs.

Flows to hedge desk → LME Zinc
100 MT of Z120-coated galvanised coil × 3% Zn coating = 3 MT Zn hedgeable → hedge on LME Zinc. Base steel (~97%) is not LME-Zn-hedgeable.
