metalled

Metalled refers to a surface that has been covered with metal or a metallic substance. This can encompass a wide range of applications and materials. In the context of roads and pathways, "metalled" typically describes a surface constructed from crushed stone, gravel, or similar aggregate that has been compacted and bound together. This type of surface is often referred to as a macadam road or a gravel road. Historically, metalling was a common method for improving unpaved surfaces, making them more durable and less prone to rutting and mud. The term "metalled" suggests a hard, stable surface, distinct from dirt or mud.

Beyond road construction, the term can be used more generally. For instance, a piece of equipment might be described as "metalled" if its components are coated or plated with metal for protection, decoration, or improved conductivity. In some older or specialized contexts, it could also refer to the application of metal leaf or plating to an object for aesthetic purposes. The specific material and method of "metalling" will vary greatly depending on the intended use and the desired outcome. The fundamental concept remains the introduction of a metallic element to a surface to alter its properties.
