| When steel was introduced into construction at the beginning of the 20th century, a new affordable building material became available for roofing. Metal was rolled into flat sheets, stiffened by ridges, then dipped into molten zinc to protect them from corrosion. All of this, when fabricated by an automated process in a steel mill, produced the cheapest and most available metal roofing material on the market, and its use grew tremendously. Over time, it was also used as building siding, particularly on industrial buildings, where fire concern was an issue. |
