Galvanized steel coil prices move with three things: substrate cost, zinc, and freight. Cold-rolled substrate follows iron ore and coking coal, while the zinc coating adds a cost tied to LME zinc—heavier Z-numbers cost more. Energy, mill utilization, and regional duties shift the base price monthly. Then add width, thickness, coating, spangle, and quantity: non-standard sizes and small lots carry premiums. Get quotes stating pricing basis, validity, and tolerance, and compare landed cost per square metre, not per tonne.
