When considering your next pallet racking solution, you’ll face the choice between welded and bolted uprights (the vertical supports running from the ground to the top of the rack). Both are reliable options that will support your needs, but there’s a noticeable trend towards the increasing popularity of bolted pallet racking in North America. While North America has traditionally used welded uprights, the rest of the world has favored bolted uprights for pallet racking. Nearly two decades ago, American racking manufacturers began producing bolted racking, and its use has been steadily increasing. Here are five reasons for the growing popularity of bolted racking:
5 Benefits of Bolted Upright Pallet Racking
Costs of Manufacturing
The production of bolted racking is generally less expensive due to the elimination of labor and welding costs. These savings can then be passed on to the customer.
Economical Repairs
Repairing bolted frame racking is simple and economical. The damaged section can be easily identified, removed, and replaced. Conversely, repairs on welded frame racking require cutting, grinding, welding, and painting, making the process more time-consuming and costly. Additionally, it is more challenging to verify the effectiveness of repairs on welded frames.
Seismic Considerations
The movement caused by seismic activity can be harmful to racking. Bolted racking, being less rigid, offers more flexibility and resilience during such events. In contrast, welded frames are less forgiving and are more likely to crack or break during seismic activity.
Customization of Racking
Bolted uprights allow for easy and cost-effective customization. The adjustable bracing can be repositioned along the uprights, enabling the columns to be cut to various heights. Customizing welded racking, however, requires a process similar to making repairs: cutting out braces, shortening the column, rewelding, and repainting. It’s important to note that many engineers find it challenging to approve repaired welded-frame racks.
Shipping Costs
Welded frames are shipped from the manufacturer in their larger, preassembled state, requiring more space for transportation compared to disassembled bolted frames. Bolted frames allow for more compact shipping arrangements, utilizing transport trailer space more efficiently. This space efficiency can result in transportation cost savings of up to 60%.
Common Myths of Bolted Pallet Racking
The concern that bolts may loosen over time, necessitating regular monitoring and tightening, is unfounded.
- Serrated lock nuts securely hold fast and only loosen when deliberately manipulated with appropriate tools.
- Rack installers are well-versed in properly securing these nuts, and the straightforward design minimizes potential errors.
- Even if a nut were to loosen, the rack system would retain its structural integrity because the bolt, essential for securing the braces and supports, remains in place.
FAQ’s
What are the main advantages of choosing bolted upright pallet racking over welded frames?
Bolted upright pallet racking offers several advantages, including cost savings in manufacturing, easier repairs, better seismic resilience, customizable options, and reduced shipping costs compared to welded frames.
Is bolted racking as durable as welded racking?
Yes, bolted racking is designed to be as durable as welded frames. The critical structural integrity is maintained by securely fastened bolts and serrated lock nuts, ensuring long-term reliability even under heavy loads.
How difficult is it to customize bolted upright pallet racking to fit specific warehouse needs?
Customizing bolted racking is straightforward and cost-effective. The adjustable bracing allows for flexible configuration, accommodating various heights and layouts without the extensive welding and modification required for welded frames.
Are there any disadvantages to choosing bolted upright pallet racking?
While bolted racking offers numerous benefits, it\’s important to consider installation time, as assembling bolted frames may take slightly longer compared to installing pre-assembled welded frames. However, this additional time investment is often offset by the cost savings and flexibility offered by bolted systems.
How does bolted racking compare in terms of maintenance and repair costs?
Maintenance and repair costs for bolted racking are generally lower than those for welded frames. Simple repairs involve identifying and replacing damaged sections, whereas welded frame repairs often require extensive cutting, welding, and repainting, which can be more time-consuming and costly.
What precautions should be taken regarding bolted racking and seismic activity?
Bolted racking, with its flexibility and resilience, is well-suited to handle seismic movements. The design allows for slight movement without compromising structural integrity, whereas welded frames are more susceptible to cracking or breaking under seismic stress.
How can I ensure the longevity and safety of bolted upright pallet racking in my warehouse?
Regular inspections and maintenance by trained professionals ensure that bolted racking remains safe and functional over time. Monitoring for any signs of loose bolts or wear ensures early detection and prevents potential safety issues.
Conclusion
Bolted upright pallet racking stands out for its cost-effectiveness, ease of customization, and resilience during seismic events. It offers efficient shipping and simpler maintenance compared to welded frames. This shift reflects its suitability for modern warehouse needs, providing both operational flexibility and long-term cost savings. Choosing bolted racking ensures robust storage solutions that meet today\’s demands effectively.
