[1855-60; obs. terne ( < F: dull; see TARNISH) + PLATE1]

* * *

Steel sheet with a coating of terne metal, an alloy of lead and tin applied by dipping the steel in molten metal.

The lead content gives terneplate a dull appearance, a noncorrosive surface, and solderability. The tin (12–50% of the alloy) wets the steel, making possible the union of lead and iron, which would otherwise not alloy. While it is still used for roofing, gutters and downspouts, casket linings, gasoline tanks, oil cans, and various containers, it has largely been replaced by other, more durable steel products that are easier to manufacture. See also galvanizing, tinplating.

      steel sheet with a coating of terne metal, an alloy of lead and tin applied by dipping the steel in molten metal. The alloy has a dull appearance resulting from the high lead content. The composition of terne metal ranges from 50–50 mixtures of lead and tin to as low as 12 percent tin and 88 percent lead. The tin serves to wet the steel, making possible the union of lead and iron, which would otherwise not alloy. Terneplate is made by a process similar to galvanizing or tinplating—i.e., by dipping the sheets into a series of heated baths, the first of a zinc chloride flux, followed by the molten terne metal, and finally one of palm oil. Terneplate has the strength and formability of steel and the noncorrosive surface and solderability of terne metal. While it is still used for roofing, gutters and downspouts, and casket linings and in the manufacture of gasoline tanks for automobiles, oil cans, and containers for paints, solvents, resins, and so on, it has largely been replaced by other, more durable steel products that are easier to manufacture.
