* The calculation basis for the sale price is our published upper copper quoted on the exchange for copper on the day prior the day the order is received. The sale price is increased or reduced by the difference between the copper base price and the copper quote. The copper number is multiplied by the copper difference. If not otherwise stated, the copper number applies per 1000 m. Other metal surcharges (e.g. aluminum, nickel, lead) are handled equivalent to the copper calculation. All information without guarantee.
