Norwegian industry encompasses a variety of companies producing a wide range of physical products. These products are either sold directly to consumers (e.g., textiles, chairs, plows, paint) or used as components in composite products (e.g., car parts, boat propellers, circuit boards, navigation systems). Additionally, Norwegian companies manufacture technology and production equipment essential for other businesses (e.g., 3D printers, packaging machines, robots, machining equipment, control systems). This sector is collectively known as manufacturing, which in Norwegian refers to industrial production.
