Types Of Stack Racking Storage
Stack racking storage refers to a type of shelving or storage rack system used to organize and store various materials, equipment, or inventories in a systematic and efficient manner. It typically consists of multiple horizontal tiers or rows of open, stackable trays, bins, or boxes that can be easily accessed and stacked vertically to maximize space. Some common types include:
Selective Pallet Racking
This is the most common type of pallet racking. Each pallet is directly accessible in selective pallet racking, so forklift operators can retrieve any pallet without moving others. It is ideal for warehouses with diverse product lines and high inventory turnover.
Narrow Aisle Racking
Narrow aisle racking reduces aisle width while maintaining accessibility. With the use of specialized equipment like narrow-aisle forklifts, businesses can increase storage density without sacrificing efficiency. This type of racking is often used in warehouses with medium turnover rates and limited space.
Dynamic Pallet Racking
Dynamic pallet racking, such as gravity flow racks, uses wheels or rollers to create a first-in, first-out (FIFO) inventory system. This type of racking is suitable for warehouses that handle perishable goods, like food and beverages, and require timely rotation of stock.
Drive-In/Drive-Through Racking
In drive-in racking, forklifts are allowed to enter the rack bays to deposit or retrieve pallets from the back or front, depending on the system. It maximises storage capacity by allowing dense stacking of pallets. This type of racking is commonly found in warehouses with high volumes of stale inventory.
Material And Design Of Stack Racking Storage
Materials Used In Stack Racking Storage
Stack racking storage systems are constructed from various materials, each offering unique benefits concerning strength, durability, and weight capacity.
- Steel:Owing to its immense strength and rigidity, steel is the most popular material for industrial storage racks. Steel stacks are available in steel of various grades, including stainless steel, which provide protection against moisture and chemical damage, making them ideal for harsh environments.
- Wood:Wooden stacks are typically made of plywood or hardwood, which are suitable for home and workshop usage. Wood is an easily adjustable and renewable material; hence, it can be used for rustic or vintage decor styles. Moreover, wooden racks can be finished with varnish or paint to enhance their durability and aesthetics.
- Plastic: Plastic stacking rack systems are designed with polypropylene, polyethylene, or ABS plastic, which are lightweight and inexpensive. Plastic options usually include moisture resistance and are easily moved or adjusted, making them ideal for light-duty use, especially in areas requiring high humidity.
- Metal (Other Than Steel): Other metals, such as aluminum, are lighter and rust-resistant. These are ideal for specific environmental conditions but are usually more expensive.
- Hybrid Materials: Stacking rack systems can also be constructed from hybrid materials, combining metals and plastics, often with additional features such as wheels or collapsible designs for extra mobility and versatility in compact spaces.
Design Features Of Stack Racking Storage
- Load-Bearing Capacity: The stack rack design is influenced by the quantity and the type of materials to be stored. Stronger beams and shelves are specified for higher loads to maintain structural integrity and prevent collapse.
- Stack rack storage systems are usually open-frame in designs, including open shelving, which makes it possible to store different items like containers, boxes, or pallets. Such a design promotes flexibility in storage.
- Tier Configuration: Multi-tier or adjustable tiers are provided in stack racking systems. These enable the height of the shelves to be changed according to the size of the stored items and the available vertical storage space.
- Accessibility: The design of the stack racking system is concerned with making the stored items easily accessible. Rolling drawers, pull-out shelves, or sloped bases are designed to ensure that items can be easily retrieved and replaced.
- Modular Design: The stack storage racks are usually designed to be modular and can be expanded or reconfigured easily as the needs or requirements for storage change over time.
Applications Of Stack Racking Storage

- Warehouse: Warehousing and distribution centers use stack racks to store pallets of bulk items. It organises stock piling and makes it easier to store and retrieve items during order fulfillment. Stack racks are often used to temporarily hold items during peak seasons or special promotions in overflow or short-term storage.
Institutional And Commercial Applications
- Library:Stacked racks are found in libraries to store books and other related materials systematically. It provides easy access and maximizes constrained space, thus enhancing the organization of the library collection.
- Hospitals, clinics, and other healthcare facilities use stacking racks to store frequently used medical supplies, equipment, and pharmaceuticals. The method of stacking helps to categorize items according to usage to enhance retrieval efficiency and space management.
How To Choose Stack Racking Storage
- Weight Capacity: Stack racking storage systems should be selected depending on the load it will carry. The materials to be stored determine the weight-bearing capacity of the rack. Ensure that the chosen rack has enough capacity and does not exceed the maximum limit.
- Material Quality:Look for the material used in the racking design. Stainless steel and corrosion-treated steel are preferred for heavy-duty or outdoor applications. For light-duty storage, engineered wood, plastic, and metal may be suitable.
- Accessibility: How accessible the stored items should also be considered. If the items are stored frequently, select a rack with open or sloped shelves, pull-out tiers, or easy slide bins to provide access. Less handled items can be stored in stackable containers or closed bins.
- Space Constraints:If there are constraints to space, the requirements of stack racking storage should be according to the available space. Measure the height and width so that the racking unit can fit adequately into the area intended for it. Consider using tiered designs that maximise vertical space.
- Expandability: Future storage needs may also be considered. If there is a possibility of future growth, select a racking system that is expandable or easily adjustable in height and width for further enhancements.
- Cost Considerations: Other factors to consider include the available budget versus benefits. Different racking systems have different price tags, depending on materials and designs. Weigh the cost against the savings in space and efficiency.
