Types of High-Density Storage Systems

Floor space is a scarce resource in any warehouse. Different types of storages shelves have helped eliminate part of the problem by giving you a place to store goods.

The problem is that you generally need to create an access aisle next to each storage shelf so that you can reach the items when you need them. In an average layout, static access aisle space between shelving units can take up to 60% of your floor space.

The solution is to use a high-density storage system. This is a system designed to minimize the need for access aisles. There are many options available.

Is high-density storage right for my business?

It’s time to consider a high-density storage solution if you feel that your business:

• has more inventory than space
• lacks efficiency in finding, retrieving or stocking inventory
• has out of control inventory handling costs
• is facing high costs to build on extra space

An internet search for a high-density storage system for online sale will give you a list of suppliers, like SRS. Make sure that you choose a reputable supplier that meets all safety and quality compliance requirements.

What types of high-density systems are available?

Pallet flow racks

Pallet flow racks are designed to use the force of gravity for inventory to move safely on rails from one side of a shelf to the other.

New pallets are loaded onto one side of the system. It glides gently at a subtle downward angle and rests against older inventory. A forklift will retrieve the palette at the furthermost end which triggers the pallets behind it to gently slide into place for collection. This solution supports the notion of first in first out inventory storage.

Industrial Pallet Racks

Pushback pallet rack

Pushback pallet racks also work with the force of gravity, but this time, the slight incline slides the pallet on a rail to the front end of the system and not to the back.

When newer pallets are placed on the shelf, they push the older pallets towards the back. But when a pallet is retrieved from the front of the row, the back pallets shift forward on the rails where the front one rests, ready for collection.

This supports the concept of last in first out inventory storage.

Drive-in and drive-thru pallet racking systems

A drive-in and drive-thru pallet racking system allow a forklift to drive into the storage racks to place or retrieve pallets. This eliminates the need to access isles that consume floor space.

Loads must be a width that can rest securely on side rails because there is no solid shelving to support the load. Only inventory with the same SKU can be stored in the one row since a forklift can only retrieve the closest pallet. This system is only suitable for first in last out inventory requirements.

Mobile pallet racking

Mobile pallet systems use racks that can be pushed up against each other using a system of floor tracks. They are compressed into a smaller floor space because you don’t need static aisles next to each rack.

When you need to access a particular rack, then the rest are pushed aside to create a single access aisle next to the target shelf. Mobile pallet racks are popular solutions in warehouses, freezers or cold storage facilities that need compact, heavy-duty storage.

Mobile shelving units

Mobile shelving units work on the same concept as mobile pallet racking systems but are designed on a smaller scale.
The racks of shelves are installed on a solid base and slide back and forth on track-rails. Units can be operated either manually or electronically. The choice usually depends on the total weight you anticipate loading in each rack.

These shelving units are popular for file or inventory storage. It’s a popular solution for filing large amounts of sensitive records like in government buildings, law enforcement offices, commercial businesses or healthcare facilities. Museums, galleries, and libraries keep valuable assets safe when they are not in circulation.

They are a compact solution for inventory storage in businesses like automotive, horticulture or industrial industries.

Greater efficiencies with high-density

This list shares some, but not all of the options available. Whichever you choose, you can be sure that the high-density system will provide a storage solution to minimize access aisle space and maximize storage space.
