Extension springs are important components in various mechanical systems, providing the force needed to extend and retract parts. They come in a variety of types and designs, including Extension springs with loop ends, extension springs with hook ends, and custom extension springs. These springs are designed to absorb and store energy, releasing it when the spring is extended or pulled.

Metal wire grid panels are also commonly used in warehouses and storage facilities to organize and store a wide range of items. The panels can be attached to walls or placed on freestanding racks to create shelving units for storing boxes, tools, or other items. The grid pattern allows for easy visibility and access to stored items, making it easy to keep inventory organized and easily accessible. In addition, the panels can be used to create dividers and partitions within a storage space to create separate sections for different types of items.
