What is a carpenter's tape measure primarily made of?

A carpenter's tape measure is primarily made of plastic or metal because these materials offer the necessary durability, flexibility, and accuracy required for measuring various distances on construction sites or woodworking projects. Metal tape measures, often made of steel, provide high strength and resistance to wear, while plastic ones can be lighter and more flexible, making them easier to handle and less prone to rusting or corrosion. The combination of these materials allows for the tape to be used over and over again without significant degradation, which is essential for the precision needed in carpentry and other trades.
