Pallet racking is a common organizational system used to stack objects in horizontal rows with many levels. In a warehouse, it takes advantage of vertical space by using racks for assisting with storage. Objects stored in these spaces are transported to vehicles and vice versa by means of forklifts or other systems which assist with simple and efficient movement.
What is the purpose of a warehouse pallet racking system?
There are many utilities of a warehouse pallet racking system. Pallet racks allow you to make the most of the storage space in your warehouse. This helps to reduce clutter on your warehouse floor and arrange objects systematically, especially in storage sections with a high density of materials.
A warehouse racking system helps to double (and sometimes triple) your storage capacity. It eases the process of transporting materials by using forklifts which makes the process systematic and efficient. In addition, having a racking system can improve your workers’ productivity by serving as an organization tool for performing operations. Ultimately, installing a pallet racking system can be more cost-effective than increasing the size of your warehouse.
Frequently asked questions (FAQs) about warehouse pallet racking
If you are building a racking system for the first time, there are several elements you need to consider. In this section, we will explore answers to some frequently asked questions about pallet racking for warehouses.
Do warehouse pallet racks need to be bolted to the floor?
Yes, all rack columns are required to be bolted to the floor, according to the Rack Manufacturers Institute (RMI). This consists of both aisle columns and rear columns on all frames. All columns need to have a base plate in addition to anchor bolts that satisfy design specifications set out by the RMI. This setup enables pallet racks to stand upright to ensure safety of warehouse personnel.
How high can warehouse pallet racking go?
The Occupational Safety and Health Administration provides guidelines on height limitations for stacking materials on pallet racks in a warehouse. If you are putting racks on top of each other without any assistance from a machine, the height should be a maximum of 16 ft. If you are using a forklift truck, the maximum height of your pallet rack is 20 ft. Regarding the appropriate stacking height for boxes, it varies based on many factors. The length, weight, and height of the box is among them. Also, keeping shorter stacks at the top of pallet racks makes it safer and less hazardous for everyone in the warehouse.
What factors impact the prices of pallet racking?
A combination of elements influences the cost of pallet racks for your warehouse. Primarily, your storage requirement influences the number of racks you will need. By looking at a list of all products that are in your warehouse, you can segregate them by weight, delivery frequency, density, and shelf life. In addition, the environment within your warehouse affects the kind of pallet racking you need. If temperature control is a component within your warehouse (such as for cold storage), there will be more associated costs.
Durable and resistant types of pallet racks are essential for preventing accidents in a warehouse. Consider the weight capacity of your racking system and check how adaptable it is for accommodating varying storage needs. In addition, your own budget influences the pallet racking that you can use for your warehouse. Though it might be affordable to choose a low-cost option, pallet racks that come in competitive prices offer more stability and better quality in comparison.
What type of pallet racking system should I utilize in my warehouse?
If your warehouse does not require heavy-density storage, selective pallet racking is the least expensive type that is ideal for this purpose. For a high-density storage need, you can choose between drive-in, push back or pallet flow racks. Both drive-in and push back systems follow the last-in-first-out (LIFO) system of inventory retrieval whereas pallet flow follows the first-in-first-out (FIFO) method.

- Do I need load capacities displayed on my racks?
- Can I use plywood instead of wire mesh decking?
- Is it safe to repair a damaged rack?
- Who can inspect racks for safety, and how often should they be inspected?
- Do racks need to be anchored to the ground?
Whether you’re a warehouse manager, a safety professional, or someone interested in pallet rack safety, this article is for you. So, let’s dive in and explore the five common racking questions.
1 - Do I need load capacities displayed on my racks?
Yes, rack load capacities are critical to the safe operation of your warehouse.
Due to safety regulations for pallet racks in North America and increasing demand for enhanced warehouse safety, it’s mandatory to have and display the rack capacity on the rack or in its vicinity.
Did you know that WorkSafe B.C. fined a construction company
more than $330,000 due to damaged racks, including their failure to
provide information regarding the rated capacity of their racks?
What are load capacities?
When it comes to warehouse safety, load capacities are a critical consideration.
A pallet rack load capacity determines the maximum weight limit a particular rack can support. Exceeding that limit can cause rack columns to become unstable, increasing the risk of collapse and employee injuries. For example, a rack designed to hold lightweight items should not be used to store heavy, bulky items, as this can lead to overloading and instability.
In addition to preventing overloading, load capacity displays can be helpful tools for conducting regular safety inspections. By checking them during inspections, you can identify any racks that may be at risk and take corrective action before a disaster occurs.
What is the responsibility of the rack owner?
The ANSI/RMI Standard mandates the display of load plaques in rack installations. It’s worth mentioning that building and safety inspectors may require the installation of such plaques. The plaques must include specific information such as:
- Maximum permissible unit load (i.e., the total weight of the product and its storage container or pallet), as well as the maximum uniformly distributed load per level.
- Average unit load, if applicable (typically calculated by dividing the maximum total product weight by the number of beam levels in the row).
- Maximum total load per bay.
It’s important to note that any changes to the rack’s configuration must be evaluated, like adjusting the beam’s height or removing/replacing a beam with different specifications. A qualified rack design engineer must recalculate the system’s capacity, create new load plaques, and attach them to the rack system to ensure that the load capacity is accurately reflected.
Were you aware that in Canada, only a professional engineer
is authorized and insured to determine the load capacity
of a pallet rack system?
Where should load capacities be displayed?
The load capacities should be marked and visible to all workers using the warehouse racks.
There are several ways of communicating the load capacity of a racking system. One can use adhesive labels placed on the first beam (at eye level) since it allows for a varying load capacity throughout a rack system. Load capacity labels placed on each bay are the most common ways of displaying this information.
If your racks have the same load capacity throughout, you may use rated load plaques at the end of the aisles to remind the forklift operators of the rack load capacity before entering that aisle. It ensures that the maximum load capacity is communicated to forklift operators so they do not overload the racks.

2 - Can I use plywood instead of wire mesh decking?
A few options for pallet rack decking are available, but the most common ones are wood and wire mesh decking. Wire decking is still popular for pallet rack systems. Plywood or timber can sometimes provide an interesting alternative.
To answer the main question, we need to consider various factors:
- The purpose of the decking.
- The load capacity.
- The fire safety.
- The cost-effectiveness of the materials.
Purpose of the decking
Wire mesh decking provides better airflow, visibility, and drainage, which is especially important for storing products that require good ventilation or have fire safety concerns.
Plywood decking, on the other hand, may not provide the same level of ventilation or drainage. Therefore, it may only be suitable for some products.
Load capacity of the decking
Pallet rack wire decking is designed to support heavy loads and has a higher capacity than plywood decking. It would be better if the racking system is intended to hold heavy loads. Additionally, wire mesh decking is more resistant to damage from heavy items.
Plywood may be acceptable when storing lighter-weight products or when items packaged in boxes are not likely to damage the plywood, such as in a picking area without pallets. Additionally, it can help prevent smaller items from falling through the decking
Fire safety
For more 4 direction radio shuttleinformation, please contact us. We will provide professional answers.
Wire decking for commercial pallet racking is more fire-resistant. It allows smoke and heat to rise, and sprinkler water can reach the lower levels through the storage rack, reducing the risk of fire damage to the stored products.
In contrast, plywood is combustible and may pose a fire hazard in certain situations. With a ceiling-only sprinkler system, water cannot reach the fire if it is blocked by wood decking.
Cost-effectiveness
Wire mesh decking tends to be more expensive than plywood, but it is more durable and has a longer lifespan.
Plywood decking may be a cheaper alternative but requires frequent replacement and maintenance.
Here are other things to consider surrounding the use of wood as decking:
- Dirt may accumulate on the plywood over time. Not as much when using wire mesh.
- Plywood decking can fall from the rack and become a hazard. They should be fixed to the beams.
- Plywood may block overhead lighting and reduce visibility into the racking system.
Key takeaways for choosing between wood and wire mesh decking
Ultimately, the decision of whether to use plywood or wire mesh decking will depend on the specific needs of your warehouse and the products you are storing. When deciding, it is essential to consider the weight and nature of the products, the level of protection required, and the budget for the decking.
While the Rack Design Code MH16.1 (RMI) does not provide specific guidelines regarding decking use, we recommend wire mesh decking based on the benefits mentioned below.
Wire Mesh
Pros
• Protects from falling objects.
• Durable material with a longer lifespan.
• Openings let sprinkler water reach lower levels (to prevent fire damage better).
• Better airflow and visibility.
• A variety of wire mesh decking to fit different beams.
Cons
• More expensive than wood decking.
• Ensure decking is not deformed/detached from beams.
Wood
Pros
• Affordable solution.

They are also well-versed in safety regulations and can ensure that the racking system follows safety standards.
Conducting a comprehensive third-party inspection before undergoing an OSHA audit is highly advisable. This inspection should evaluate the condition of your warehouse’s pallet racking systems to identify any issues hindering compliance with OSHA regulations. They may include improper pallet rack installation, hazardous damage, unposted capacity, or unsafe modification. Addressing these concerns before an OSHA visit can help you avoid potential fines and temporary suspension of operations.
How often should racks be inspected?
Rack inspections should be conducted regularly to identify any damage before it becomes dangerous and poses a risk of accidents. The frequency of inspections depends on several factors, including the type of rack, the load capacity, the level of use, and the environmental conditions in which the rack is located.
As a general guideline, a professional rack inspector should inspect racking systems at least once a year. However, more frequent inspections may be required in high-traffic facilities or those with heavy usage or frequent loading and unloading.
Additionally, it is recommended that warehouse racks be inspected after any damage or significant change to the rack system occurs, such as:
- Collisions.
- Overloading.
- Seismic activity.
- Other incidents possibly compromising the safety of the racking system.
As well as annual inspections, conducting thorough monthly checks of your industrial pallet racks is crucial. Warehouse personnel should be trained to identify any visible damage or signs of wear and tear, such as bent or broken beams, loose connections, or missing bolts. Any damages found should be reported to the rack safety expert for further inspection and repair.

5 - Do racks need to be bolted to the ground?
Yes, pallet racks should be anchored to a concrete slab to ensure stability, provide resistance to small impacts, and prevent them from tipping over.
OSHA has taken measures to ensure that businesses that do not correctly anchor their commercial pallet racking are cited for violations. Although avoiding a fine from OSHA is a significant motivator to fasten your racks securely, the potential risks of employee injury or structural damage to the building associated with an unstable rack are more compelling reasons.
Furthermore, if a forklift collides with an unanchored pallet rack, it could trigger a catastrophic chain reaction, like a domino effect, if the surrounding racks are not adequately strengthened. It would result in significant losses ranging from thousands to millions of dollars in damaged inventory.
The anchoring method used for warehouse racks can vary depending on the specific installation site and type of rack. Some common anchoring methods include wedge anchors, screw anchors, or sleeve anchors.
To ensure the appropriate anchoring technique is used for a specific application, seek the advice of a professional engineer or installer. Following the manufacturer’s recommendations and applicable regulations or standards is crucial when selecting and installing anchors. The Rack Manufacturers Institute’s guidelines provide suggestions on the suitable anchor bolts to use for pallet racks. Additionally, please note that seismic anchors are necessary for racks in areas with a high risk of earthquakes.
In addition, regular inspections of rack anchors are also essential for maintaining the racking system’s safety. Over time, anchors may loosen or become damaged, compromising the stability of the racks. Qualified rack safety experts should perform inspections at least once a year to ensure proper safety. If any damage, such as cracks or splits in the concrete or bolts, is detected, they should be addressed immediately.
Key Takeaways for anchoring pallet racks
Properly anchoring warehouse racks to the floor or foundation is necessary to prevent accidents and injuries. The appropriate anchoring method should be determined based on the floor type and load capacity, and regular inspections should be carried out to ensure that the anchoring remains secure.
Regular inspections are also important to ensure that the anchors are still effective. By taking these measures, you can ensure the stability of your racking system.
