Metal racks, also known as metal shelving or metal storage racks, are storage systems made primarily from metal materials. They are widely used in various industries and applications for efficient organization and storage of goods and materials.

Here are some common types of metal racks:

1. Boltless Shelving:

- Structure: Boltless shelving consists of metal uprights, horizontal beams, and metal shelves. The components are designed to be easily assembled without the need for bolts or special tools.

- Adjustability: Boltless shelving typically offers adjustable shelf heights, allowing for customization to accommodate different product sizes and storage requirements.

- Versatility: Boltless shelving is versatile and can be used for storing a wide range of products, including boxes, cartons, small parts, and lightweight items. It is commonly used in warehouses, offices, retail stores, and garages.

2. Pallet Racking:

- Structure: Pallet racking is a type of metal rack system designed for the storage of palletized goods. It consists of upright frames, horizontal beams, and wire mesh or solid metal decks.

- Selective Pallet Racking: Selective pallet racking is the most common type of pallet racking. It provides direct access to each pallet, allowing for easy stock rotation and retrieval.

- Drive-In/Drive-Through Racking: Drive-in and drive-through racking systems allow forklifts to drive directly into the rack structure for storage and retrieval. They are suitable for high-density storage of homogeneous products with low turnover.

- Push-Back Racking: Push-back racking utilizes inclined rails or carts to store pallets in a last-in, first-out (LIFO) configuration. Pallets are loaded from the front and pushed back by subsequent pallets.

3. Cantilever Racking:

- Structure: Cantilever racking is designed for the storage of long and bulky items such as pipes, lumber, and steel bars. It features vertical columns with horizontal arms that extend outward to support the load.

- Versatility: Cantilever racks can be customized with adjustable arms to accommodate different lengths and weights of items. They provide easy access to stored items without obstruction from uprights or front beams.

4. Wire Shelving:

- Structure: Wire shelving is made of metal wire frames and shelves. It is lightweight, durable, and provides excellent visibility and airflow.

- Application: Wire shelving is commonly used in commercial and industrial settings, such as retail stores, healthcare facilities, and food storage areas. It is ideal for storing items that require ventilation, such as perishable goods, electronics, and small parts.

5. Mezzanine Racking:

- Structure: Mezzanine racking systems involve the installation of a raised platform or mezzanine level within the warehouse or facility. The structure is typically made of steel and can support various types of metal racks for additional storage capacity.

- Benefits: Mezzanine racking systems maximize vertical space utilization by creating additional levels for storage. They are commonly used when floor space is limited, allowing businesses to expand their storage capabilities without the need for extensive construction.

These are just a few examples of metal racks commonly used in storage and organization settings. The specific type of metal rack chosen depends on factors such as the type of items to be stored, available space, load capacity requirements, and operational needs.
