Storage Systems & Types

The term “Storage” refers to the physical act of storing the materials or stock in a warehouse, on pallets, shelves, racks, boxes, bins etc. with the objective of retrieving them later for issue or dispatch to the customer or internally. Warehouses have secured spaces where inventory is stored before shipping it out to the end customers. A warehouse gives better control over the inventory and ensures that customers receive on-time delivery of products, ultimately leading to higher profits.


Warehouses may employ either one or a combination of different types of warehouse storage systems. Depending on the system’s efficiency, warehouses can greatly improve the order fulfillment and picking processes. An organized storage system is also the key to promoting a safer workplace environment. It helps in avoiding any potential hazards that may endanger warehouse employees as they handle heavy machinery and move about the warehouse.

Objectives of Storage

The main objectives of storage are:

  • Maximum Utilization of Space
  • Accurate identification of the materials stored
  • Ease of storing and picking
  • Protection of the materials

Storage Methods

Storage can be in silos, in piles, on the floor or in the yard.

Block Stacking

The materials, usually in containers are stacked on top of one another till a maximum safe height.

Materials are stored on shelves.

This is often used to store palletized goods. One pallet is stored on the stacking side of the rack. If forklifts are used racks can go up to 30 feet and if overhead stacker cranes are used, racks can even go up to 60 feet.

Types of Storage Equipments

Some of the types of storage equipment generally used are –

Concrete Pigeonholes

These are used for bulk storage of heavy items, particularly in the receiving section. This method is used for storing paper items, bulky packages etc. The pigeonhole sizes may vary from 2’x2’x2’ to 4’x4’x4’.

Wooden Shelves

These can be built to various sizes. They are normally cheap and light in weight. However, they are not durable.

Steel Shelves (Closed or Open)

These are widely used, can be built to any required dimension and are durable. There is complete flexibility, interchangeability and adaptability.

Steel Bins

A bin is a compartment or pigeonhole that is fitted with a bin front. Different sizes are available and are used for storing hardware items, ball bearings, metal parts etc. Bins give protection to materials from dust and dirt.

Slotted Angle Shelves

Some racks have slotted angles. The angles have holes all along their length, and the shelves can be fixed at any point desired, truly providing flexibility to the gap between two shelves. The cross members can be changed to a different position. Flexibility and durability are the characteristics of these types of shelves.

Boltless Shelves

      This is a slight variation of slotted angle shelves. Here, instead of holes that enable two bars to be bolted together, there are pockets into which a short bolt can slide into the upper bar. Such shelves are used generally for heavy parts and can be erected to a tall height.

Light duty cantilever shelving

      Shelving is supported on steel cantilever arms, which pass through central steel uprights. Shelf levels are adjustable.

Long span adjustable shelving

      These are designed to meet span requirements exceeding 900mm and load up to 500kg per shelf.

Mobile storage bins

The racks or bins themselves are made to move. Usually, the bins move upon fixed rails. In some cases, bins are capable of free movement. One end of the rack is mounted on wheels and the opposite end is on stands. The end with the stands is hooked to a forklift truck.

Tote Pans

These are unit containers. They not only provide an improved storage factor, but also facilitate counting, dispensing, handling, checking and issue.

      Racks are of two types – racks for string raw materials such as sheets, bars, sections, or rolls of materials; and racks for storing unit storage equipment, including pallets, tore pans etc.

Some special types of racking are

Roll-through Racking

      Racks are filled with rollers on which the goods rest. The goods enter through one face of the rack and then exit from the opposite side, which is inclined with respect to the stacking face.

Drive-through Racking

      Goods are stored in depth in high racks up to 30 feet and the forklift can go through the racks and pick up pallets from where they are stored at heights.

Mobile Racking

      Racks are mounted on rollers and are moved to make way for a particular rack to be operated.

Advantages of Storage Equipment

The right storage system within the warehouse can truly make a world of difference. However big or small the warehouse, if it is unorganized it will directly affect productivity. A smart and efficient storage system will not only organize the current inventory but it will also make space for new inventory.

  1.       Safety: Due to the kind of work being performed and the weight of all the products involved, warehouses can naturally be dangerous environments. However, with a cluttered warehouse, safety risks can increase tenfold. The safety of employees, inventory, tools, and machines, should always be a top priority. An organized warehouse is a safer warehouse. With an organized system, the products or goods have designated places, that way they stay safe and well protected.
  2. Efficiency and Productivity: A good inventory management strategy is backed by an organized warehouse. If the warehouse is cluttered or disorganized, managing inventory becomes tough. Inventory should be stored in a way that not only allows one to make the most of available space but also assembles it in a neat and efficient way. This ensures that inventory can be located and retrieved in a quick and efficient manner. This, in turn, helps speed up the order fulfilment process and keeps customers happy.
  3. Saves Time and Money: A warehouse that is organized will improve the accuracy of inventory orders. A well-kept storage facility helps figure out exactly how much inventory is needed to have on hand. This will let not only prevent product shortages but also allow storing just enough inventory without keeping any excess in the warehouse. When inventory is neatly displayed, the effort of having to do an inventory recount to ensure records are accurate is eliminated.
  4.  Optimizing the Space Available: Businesses are always on the lookout for space to store new inventory. One of the biggest benefits of investing in a modern and comprehensive storage system is that it maximizes the utility of the available space in the warehouse for inventory storage. Reinventing an existing warehouse system turns out to be a lot easier and more cost-effective than acquiring a new warehouse or office altogether.

A cluttered or disorganized warehouse means setting the business up for potential inventory errors and challenges.
