Show SHEET ZINC. A seming anomally is found in the fact that in the United States "tin-plate" is the favorite roofing, the use of sheet zinc for roofing being almost unknown; and yet in England, the home of the tin-plate industry, and in all parts of Europe zinc is now the most favored fav-ored material. A roof of good tin, properly laid and painted thoroughly at least once in every three years, will last from twenty to thirty years; the life of a slate roof may be from thirty to fifty years, while the life of a zinc roof maybe estimated from the fact that the first zinc roof ever put up,' in 1811, exists to-day in good condition. |
