Steel fencing is the strongest fence possible. Steel is an alloy of iron and carbon, although it is sometimes combined with different metals such as tungsten and chromium for other desirable characteristics. It is often the fence of choice in very dry inland climates like in the American West where anecdotal evidence suggests it sees very little rust.
How Steel is Made: a Brief Summary of a Blast Furnace: There are two types of metals, ferrous & non-ferrous. Ferrous comes from, or contains iron, while Non-Ferrous does not contain iron. Some examples of ferrous metals would be mild steel, cast iron, high strength steel, and tool steels. Examples of non-ferrous metals would be copper, aluminum, magnesium, titanium, etc. To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added.
