This is a form of iron that is known for its toughness and malleability. It has a very low carbon content (less than 0.08%) and is worked (or "wrought") by hand, often through hammering, bending, and shaping. It was widely used historically for decorative fences, gates, and railings due to its ability to be molded into intricate designs. Today, true wrought iron is rare and mostly found in historical restoration projects.
Historically, "rod iron" referred to a specific form of iron that was created by cutting up wrought iron bars. In modern terms, "rod iron" often refers to round, slender bars of steel or iron that are used in construction or for making items like railings and gates. The term is now loosely used to describe iron rods, but these rods are typically made of steel, not true wrought iron.
