BWG 21 refers to the Birmingham Wire Gauge (BWG) system, which is commonly used to measure the thickness or diameter of wires. In the BWG system.

For galvanized iron wire, BWG 21 corresponds to a diameter of approximately 0.81mm or 0.032 inches. Galvanized iron wire is coated with a layer of zinc to protect it from corrosion, making it suitable for various applications such as fencing, construction, and crafts.
