• Double-Deep Racks: Enhances storage capacity by storing two pallets deep; requires specialized forklifts for access.
• Push-back Pallet Racks: Uses nested carts on inclined rails to push pallets back as new ones are loaded, optimizing space and accessibility.
• Drive-in Pallet Racks: High-density storage that allows forklifts to enter from either end, commonly used for bulk storage.
• Pallet Flow Racks: A gravity-fed system designed for FIFO (First In, First Out) inventory management, ideal for perishable goods.
• Cantilever Racks: Best for long, bulky, or irregularly shaped items like pipes, lumber, or steel bars.
• Stack Racks: A flexible and portable storage solution, often used for seasonal or bulk inventory storage needs.

What Are the 5 Methods of Storing Goods in a Warehouse?

You can get creative with your warehouse storage, integrating different types of storage methods. Five common methods of storing goods in a warehouse include:

1. Pallet Racking: Uses large racks to store palletized goods, making it ideal for bulky inventory.
2. Multi-Tier Racking: Stacks multiple levels of racking to store high volumes of goods efficiently within a compact footprint.
3. Shelving: Includes individual shelves to store smaller items, typically organized by category for easier retrieval.
4. Mobile Shelving: Mounted on rails and can be moved to access specific sections, maximizing floor space.
5. Mezzanine Flooring: Creates additional storage space by adding a raised platform within the warehouse to increase vertical storage capacity.

What Are Warehouse Pallet Rack Components?

While there are different configurations for pallet racking, the basic components include upright frames, shelf beams, and support items.

Upright Frames

Upright frames are made up of two metal columns that are braced internally. The columns have holes for horizontal beams to connect. You can get upright frames in a variety of heights, widths, and post sizes to handle different dimensions and weight loads.

Horizontal Beams

Horizontal beams are the rails that attach to the frame and create the shelves. Pallet rack beams support loads and attach at the front and back of the upright frames. Typically, these come in either step beams or box beams, which can support wire decking or other additional support.

Supporting Components

There are several supporting components to help manage weight loads and stability, including:

• Base plates to anchor racks in place for greater stability
• Anchor bolts to adhere racks to flooring
• Wire mesh decking to help support items on shelves and prevent them from falling through the racks
• Post protectors and guards. Also called straddle protectors, these bolt onto racks or flooring to protect pallet racks from impact from equipment such as forklifts.

Benefits of Pallet Racking Systems

The right new or used warehouse racking can make your warehouse safer and more efficient. Benefits include:

Maximizing Warehouse Space

A well-designed warehouse pallet racking system maximizes warehouse space by utilizing vertical storage. This allows you to store more inventory in a smaller footprint. By optimizing vertical storage, you can improve overall efficiency and organization.

Reducing Product Damage

Pallet racking systems help protect your inventory by preventing unnecessary movement and reducing the risk of product damage. Unlike traditional floor stacking, racks provide structured storage that keeps goods securely in place.

Lowering Labor Costs

Labor costs are typically the biggest budget item. Moreover, salaries are increasing, and it’s difficult to find and retain good workers. So, when you can reduce labor costs, you increase your profits.

Smart pallet racking systems can significantly reduce labor costs by improving efficiency in inventory management. Automated storage solutions and strategically designed racking configurations allow employees to locate and retrieve items faster, reducing the time spent on manual searching and handling.

Enhancing Organization and Accessibility

A pallet racking system keeps inventory well-organized, making it easier for warehouse workers to locate and retrieve products. This streamlined organization reduces misplacements, enhances inventory tracking, and improves order fulfillment speed, leading to increased productivity.

Minimizing Out-of-Stock Issues

Proper storage and organization of inventory through pallet racking systems help minimize out-of-stock situations. By ensuring stock levels are efficiently managed and readily accessible, you can improve order accuracy and customer satisfaction while reducing delays caused by misplaced or hard-to-reach products.

Scalable for Business Growth

As your business grows, your storage needs evolve. Warehouse pallet racking systems offer scalable solutions that allow you to expand capacity easily. Additional racks can be integrated into the existing system, providing a cost-effective way to accommodate increasing inventory, without requiring a complete redesign of your warehouse layout.

Speeding Up Shipping and Order Fulfillment

Efficient storage leads to faster picking and shipping. With pallet racking systems, items are stored in designated locations, allowing forklifts and warehouse teams to access goods quickly. This improves order processing speed, reduces shipping delays, and enhances overall warehouse workflow.

Safety: What Are OSHA Requirements for Warehouse Racking?

The Occupational Safety and Health Administration (OSHA) has specific requirements for warehouse racking, covering installation, maintenance, and inspection standards. You can review OSHA requirements on the agency’s website. In broad strokes, here are the general guidelines:

• Racking systems must be properly installed according to manufacturer guidelines.
• Load capacities must be clearly marked and followed to prevent overloading.
• Regular inspections should be conducted to identify structural issues or damage.
• Employees must be trained in safe handling and storage practices.
• Aisles must be kept clear to allow safe forklift operation and emergency access.

OSHA recently launched a three-year program aimed at reducing and preventing workplace hazards in warehouses, fulfillment centers, and distribution centers. The main areas of focus include material handling and storage, walking and working surfaces, powered industrial vehicle operation, means of egress, and fire protection.

How Safe Is Warehouse Racking?

The warehouse industry has a high rate of safety incidents compared to other industries. In fact, warehousing and transportation ranks second in the number of fatal work injuries, behind only construction.

With proper installation, usage, training, regular inspections, and maintenance, pallet racks can last for 10–20 years (or longer). The racks themselves are safe. An examination by the National Institute for Occupational Safety and Health (NIOSH) revealed that nearly every warehouse accident was preventable and caused by human error rather than equipment failure. In cases where pallet racks failed or collapsed, the most likely culprit was improper usage, such as overloading shelves or overstocking items.

What Are the Causes of Warehouse Overstocking?

Overstocking is a common problem, both for safety and tying up capital. Some of the common causes of warehouse overstocking include:

• Poor inventory management, creating surplus stock
• Seasonal demand fluctuations
• Inefficient warehouse design

In recent years, we’ve seen more overstocking than normal. Inconsistent supply chains increased the number of warehouse operators that move from a just-in-time strategy to just-in-case to avoid stockouts. This has created higher inventory levels in many cases and stressed existing storage solutions.

Does Warehouse Racking Need to Be Certified?

By the letter of the law, new or used warehouse racking does not have to be certified. As long as you meet OSHA’s general workplace standards, you’re compliant.

However.

There are good reasons to ensure your pallet racks are certified, especially when it comes to safety and liability. The Rack Manufacturers Institute (RMI) offers a voluntary certification program for manufacturers called the R-Mark^©. This certification is awarded to companies that demonstrate they can consistently design and manufacture rack systems that comply with OSHA and American National Standards Institute (ANSI) standards, including:

• ANSI MH16.1: Steel Storage Rack Systems
• ANSI MH16.3: Industrial Cantilever Storage Rack Systems
• ANSI MH26.2: Industrial Storage Rack Decking

“The review, conducted by an independent, professional rack engineer, confirms that the manufacturer has the ability to design and build rack systems that meet RMI standards.” — RMI

Such certification can be helpful in case of disputes about safety, or legal actions.

Whether your warehouse pallet racks are certified or not, following all of the manufacturer’s recommendations, proper use, and regular inspections and maintenance is essential to create a safe work environment.

What Equipment Is Used in Material Handling?

Material handling involves more than a warehouse pallet rack system. Modern warehouses are leveraging automation and other equipment for efficient material handling. This includes:

Carousels

Horizontal and vertical carousels rotate to deliver items. They reduce floor space and bring materials to pickers faster, eliminating travel time and use of other equipment.

Automated Storage and Retrieval Systems (AS/RS)

AS/RS systems utilize advanced robotics and automation to streamline high-density storage and retrieval, reducing labor costs and increasing efficiency.

Forklifts and Reach Trucks

Essential for transporting and retrieving pallets from high shelves, various types of forklifts and powered trucks are available in electric, gas, and diesel.

Conveyor Systems

Automated and manual conveyor systems facilitate the movement of goods within a warehouse, reducing manual handling.

Pallet Jacks

Manual and electric pallet jacks are also options for maneuvering smaller loads and retrieving individual items. These are commonly used in e-commerce order fulfillment.

Overhead Cranes and Hoists

Designed for lifting and moving heavy or oversized materials safely, cranes and hoists are often used in manufacturing and distribution facilities.

Lift Tables

Hydraulic or electric tables can raise materials to ergonomic heights, reducing strain on workers and improving workflow.

Pick Systems

Pick modules and robotic arms automate order picking, reducing errors and increasing efficiency in high-volume warehouses.

Hand Trucks and Dollies

Simple yet essential, hands trucks and dollies help transport smaller loads across short distances within a warehouse.
