Material Handling
…Material handling refers to the movement, protection, storage, and control of materials and products throughout manufacturing, warehousing, distribution, consumption, and disposal. It is a critical component of supply chain operations, ensuring that goods are transported efficiently and safely from one location to another. Effective material handling reduces costs, improves productivity, and minimizes product damage.
