Standard Pallet Racking Upright Sizes

The upright, or frame, is the vertical structure of a pallet rack system that holds the beams and supports the load. Understanding the dimensions of these uprights is critical when choosing the right system for your warehouse needs.

1. Common Upright Depths

The upright depth determines how far the pallet rack extends from the wall or other structures. The most common pallet racking upright depths are:

• 36 inches: Suitable for lighter loads and smaller spaces.
• 42 inches: Standard depth for most warehouse applications.
• 48 inches: Ideal for deeper shelves and heavier loads, providing greater support.
• 60 inches: Used for high-density storage and larger items requiring extra depth.

Selecting the right upright depth ensures optimal space utilization and load-bearing capacity.

2. Pallet Rack Beam Dimensions

Pallet rack beams connect the uprights and hold the pallets. They vary in size to support different load capacities. The most common beam dimensions include:

Standard Beam Lengths:

• 96 inches (8 feet): Commonly used for standard pallets.
• 120 inches (10 feet): Suitable for larger storage needs.
• 144 inches (12 feet): Ideal for extended storage and larger inventory.

Beam Thickness:

• 1.5 inches to 2 inches: Standard for lighter loads.
• 2.5 inches to 3 inches: Used for heavier loads and bulk storage.

Choosing the right beam size ensures the system can support the weight of your inventory while maintaining stability.

3. Height Specifications

Upright height is another critical factor in pallet racking dimensions. The height of the rack must align with the warehouse ceiling height and your storage needs. The common range for upright heights is:

• 8 to 12 feet: Standard for most warehouse applications, suitable for typical storage and easy access.
• 12 to 20 feet: For mid-rise storage, allowing for higher stacking without impacting efficiency.

After selecting the right dimensions, don’t forget to account for the required clearance between racks to ensure smooth and safe operations.

Required Clearance Between Racks

To ensure smooth operation and safety, it’s essential to maintain the correct clearance between racks. A general guideline for clearance is:

Aisle Width:

• 7 to 8 feet: Standard for regular operations and smaller aisles.
• 8 to 10 feet: For larger, high-volume warehouses requiring more space for movement.

Forklift Clearance:

• 3 to 4 feet: Between the racking and forklifts to allow safe maneuvering.
• 5 to 6 feet: For larger forklifts or narrow aisle systems.

Proper clearance reduces the risk of collisions and ensures easy access to stored materials.

Once clearance is established, the next step is to explore the different types of pallet racking systems and their specific dimensions for optimal space utilization.

13 Types of Pallet Racking and Their Dimensions

There are several types of pallet racking systems available, each with its own size specifications. The most common types include:

With the types of racking in mind, let’s look into the essential steps for choosing the right size of pallet racking that fits your warehouse’s needs.

7 Steps to Choosing the Right Size of Pallet Racking

Choosing the right pallet racking dimensions requires careful consideration of several factors. Here are seven steps to guide you through the process:

1. Assess Inventory Needs

The first step in choosing the right pallet racking system is evaluating your inventory. Understanding the types, sizes, and weights of the items you plan to store helps determine the required pallet racking dimensions. Key questions to ask include:

• What is the size of the pallets?

Standard pallet size is typically 48” x 40” (length x width), but you may have custom-sized pallets, such as 42” x 42” for European or other non-standard pallets.

• How heavy are the items?

The weight will impact the beam size and frame depth. Typically, the weight of the palletized goods will directly correlate to the racking system's capacity and strength.

Formula:

Average load per pallet = Total weight of items on pallet / Number of pallets.

This helps determine the load-bearing capacity needed for each rack.

2. Identify The Size And Weight Of Your Pallets

Pallet size and weight play a critical role in determining the racking system’s dimensions.

• Standard Pallet Size: 48” x 40” is the most common size, but some industries use larger or smaller pallets.
• Custom Pallet Sizes: Measure your largest and smallest pallets to ensure your racking system fits these dimensions.

For example, a 48” x 40” pallet may fit in a standard 42” rack depth, while a 48” x 48” pallet may need a 48” rack depth.

Formula:

Rack Depth Calculation = (Pallet Length + Gap for Handling) x 1.2

This ensures enough space for forklifts or other equipment to move the pallets easily.

3. Calculate Frame Depth

Frame depth is important for supporting your pallets while ensuring accessibility.

• Standard Frame Depth: 36" - 48" is common, but for heavier or larger pallets, deeper frames (up to 60”) may be necessary.
• Consider pallet depth: If your pallet is deeper than the standard rack depth, you will need more space between racks for forklift maneuvering.

Formula:

Optimal Depth = Maximum Pallet Depth + Minimum Aisle Clearance

Ensure that the pallet depth doesn’t extend too far beyond the rack to prevent wasted space and improve maneuverability.

4. Determine Frame Height

Consider the warehouse height and the types of goods you are storing when selecting the frame height. Racking height determines vertical storage capacity, but it must also balance with accessibility.

• Standard Height Range: 8-30 feet is typical for most warehouses, but custom heights can go as high as 40 feet for high-rise systems.
• Choose based on goods: If you store large items, taller racking might be necessary, but if you need frequent access to goods, shorter racks might improve workflow.

Formula:

Rack Height = Ceiling Height – Safety Clearance – Forklift Reach

Ensure the height allows for the optimal use of vertical space while leaving room for safe operation.

5. Select Beam Size

The size of the beams depends on the weight and size of the pallets you’re storing.

• Standard Beam Size: 96 inches (8 feet) is a common length for beams, but 120 inches (10 feet) or 144 inches (12 feet) can be used for larger warehouse layouts.
• Beam Load Capacity: Choose beams based on load calculations—typically, beams should support 3,000-5,000 pounds per pair.

Formula:

Beam Load Calculation = (Pallet Weight per Level) x Number of Pallet Levels per Beam

This ensures the beams can support the total weight at each level of storage.

6. Analyze Your Warehouse Space

Measure your warehouse space carefully to ensure that the pallet racking system fits within your available floor space. The system should optimize your layout for both accessibility and safety.

• Warehouse Layout: Understand your warehouse’s dimensions, aisle width, and available floor space.
• Aisle Width Calculation: Ensure there’s adequate aisle space for fork trucks and other equipment to move around. Aisle width should typically be 7-8 feet for narrow aisle systems and 10-12 feet for standard aisles.

Formula:

Total Aisle Space = Total Warehouse Width - (Rack Width x Number of Rows)

This formula helps you determine how many rows of racks fit within your warehouse while leaving room for aisles.

7. Account For Safety And Regulations

Ensure your pallet racking system meets all relevant safety standards, including those set by OSHA and other regulatory bodies.

• OSHA Compliance: Ensure the system complies with OSHA 1910.176 for material handling and storage.
• Safety Features: Consider adding rack guards, safety barriers, and load limit labels for safe operation.
• Maintenance: Regularly inspect racks for damage, including bent beams, cracked uprights, or issues caused by forklift collisions.

Formula:

Rack Safety Load Capacity = Beam Load Capacity x Frame Load Capacity

This helps ensure your pallet racks can safely hold the weight distributed across the beams and uprights.

After selecting the right size, it's critical to keep safety in mind. Let's look at the key warehouse rack safety considerations to ensure a secure setup.

5 Warehouse Rack Safety Considerations

When selecting pallet racking, it’s important to prioritize safety. Here are five safety considerations to keep in mind:

1. Load Limits: Always adhere to the load limits specified by the manufacturer to avoid rack failure.
2. Aisle Width: Ensure aisles are wide enough for forklift maneuvering, with proper clearance for operators.
3. Regular Inspections: Conduct routine inspections for damaged racks, beams, or uprights, as well as signs of wear and tear.
4. Rack Labeling: Clearly label racks with weight capacities and product type information to prevent overloading.
5. Forklift Safety: Train operators on safe forklift practices to avoid collisions with racks and ensure equipment is used correctly.

With safety in mind, understanding the key components of warehouse racks will help you make an informed decision on materials and installation.
