Warehouse Storage Rack Systems
Warehouse racking systems are composed of pallet rack, a steel structure configured in rows with multiple levels of storage for pallet loads
Warehouse storage rack systems are the most common storage methods in warehouses or distribution centers. There are many different sizes and configurations of warehouse racking, which are determined based on the customized needs of the user and the products they are storing. Warehouse racking systems also comes in many forms, from high selectivity to high density. Some of the warehouse pallet rack types are:
| Warehouse Pallet Racking System Types | Selectivity | Density | FIFO/LIFO | Pick Rate | Cost | System Size | System Height |
|---|---|---|---|---|---|---|---|
| Selective Rack - Wide Aisle | High | Low | FIFO | High | Low | Any | High |
| Selective Rack - Narrow Aisle | High | Medium | FIFO | Medium | Low | Medium to Large | High |
| Double-Deep Selective Rack | Medium | Medium | LIFO | Medium | Low | Any | High |
| Twinload | Low | Medium - High | LIFO | Low | Medium - Low | Medium to Large | Medium |
| Drive-In Rack | Low | Medium - High | LIFO | Low | Medium - Low | Medium to Large | Medium |
| Push-back Rack | Medium | Medium - High | LIFO | High | Medium | Medium to Large | Medium |
| Pallet Flow Rack | Medium | Medium - High | FIFO | High | Medium | Medium to Large | Medium |
| Shuttle System - Semi-Automated | Medium | High | FIFO | Medium | Medium | Medium to Large | Medium |
| Shuttle System - Fully Automated | High | High | FIFO | High | High | Large | High |
| Crane System - Single-Deep - Semi-Automated | High | High | FIFO | Medium | High | Large | Very High |
| Crane System - Double-Deep - Semi-Automated | Medium | High | LIFO | Medium | High | Large | Very High |

Types of Warehouse Storage Rack Systems:
There’s no one-size-fits-all solution, and different rack systems cater to specific needs:
- Pallet Racking
The most common type, offering a simple and versatile storage solution for all kinds of palletized goods. - Selective Pallet Racking
The workhorse of warehouses, providing easy access to individual pallets using forklifts. - Drive-In/Drive-Thru Racking
High-density storage solution where forklifts enter the rack itself to load and unload pallets. Perfect for large quantities of similar items. - Push-Back Racking
Similar to drive-in, but pallets sit on nested carts on rails that roll back as pallets are added, creating a “last-in, first-out” system. Ideal for perishable goods.
Benefits of Warehouse Storage Rack Systems:
- Increased Storage Capacity
Utilize your warehouse’s vertical space, maximizing storage capacity. - Improved Inventory Organization
Designated spots for pallets keep everything organized and easy to find. - Enhanced Warehouse Efficiency
Faster picking and retrieval of goods thanks to better organization and forklift accessibility. - Safety and Security
Racks can be designed to incorporate safety features like guardrails and seismic braces to protect your inventory and staff.
Choosing the Champion: Selecting the Perfect Warehouse Racking System
The ideal warehouse storage rack system depends on your specific needs. Here’s a battle plan to help you choose your champion:
- Product & Weight
Pallet racking is the go-to for hefty palletized goods while shelving systems are perfect for smaller, individual items. When selecting racks or shelves, consider weight capacity. - Inventory Turnover
Frequently accessed items need to be readily available. For a fast-moving inventory, select racking with easy-to-reach storage locations. Low-turnover items can be placed on higher shelves or in denser storage solutions.
Many factors go into the design of pallet storage rack, including pallet sizes and weights, accessibility to product requirements, forklift utilization, and many others. Some of the factors to consider for designing a storage rack system may include:
- Sizes and weights of the pallet loads to be stored
- Storage density and selectability of pallets desired
- Number of SKU’s and pallets per SKU
- Building clear height, along with fire protection limitations
- Inventory rotation requirements
- Hazardous classification of the product to be stored
Conquering the Chaos: Essential Storage Methods in Warehouses
Warehouses are the beating hearts of countless industries. They keep products flowing, ensuring goods reach store shelves and customer doorsteps. But within these bustling centers lies a constant challenge: organization. With so much inventory, implementing efficient storage methods in warehouses is crucial.
Here, we’ll explore some of the most common storage methods for maximizing space, streamlining operations, and keeping your warehouse running smoothly.
1. Pallet Racking: The Workhorse of Warehouses
Pallet racking is an absolute staple. These robust structures utilize vertical space, featuring horizontal beams supported by upright columns. Pallets loaded with goods are placed on the beams, allowing for high-density storage. Pallet racking is incredibly versatile and comes in various configurations, including:
- Selective Pallet Racking
The most common type offers direct access to each pallet for easy retrieval. - Drive-in/Push-back Racking
High-density option where pallets are loaded on rails, creating a compact storage system. - Carton Flow Racking
It uses gravity to move cartons on rollers, ideal for fast-moving items.
2. Beyond the Racking: Additional Storage Solutions
Warehouses house a diverse range of products, and sometimes, specialized storage solutions are necessary. Here are a few examples:
- Bins and Containers
Ideal for small parts, keeping them organized and accessible. - Hanging Storage
Perfect for long items like clothing or pipes, maximizing vertical space. - Drive-in/Drive-thru Buildings
Designed for oversized inventory, allowing forklift access throughout the structure.
Choosing the Right Storage Methods in Warehouses
The optimal storage solution depends on several factors, including:
- Product type and size
Pallet racking for bulky items, shelves for smaller goods. Inventory turnover
Frequently picked items need easy access, while low-turnover items can go higher up.
By carefully considering these factors and implementing the most effective storage methods in warehouses, you can create an organized, efficient space that optimizes operations and keeps your inventory flowing smoothly.
