Key Considerations When Choosing Your Ideal Mezzanine Floor
One final piece of information you need to know about mezzanine floors is to carefully assess the following aspects during the selection process. From picking the floor decking materials to considering the used mezzanines, these pointers are relatively in-depth and thus help you make a well-rounded decision.
Deciding The Floor Decking Materials
Besides catwalk platforms, which leverage the top surfaces of the below racks or shelves as travel lanes, most warehouse mezzanine floors have distinct floor decking materials, making one design different from others. The first step in designing your ideal mezzanine is to pick the decking material you want. Below are a few options:
- Steel: This material is known for its tremendous strength and durability, making it ideal for heavy-duty applications and high-traffic areas in your warehouse. Some steel types, like stainless steel, also perform reliably even in the toughest settings, thanks to their superior corrosion resistance.
- Bar grating: Similar to steel, bar grating also has a high load-bearing capacity. However, this decking option goes the extra mile by ensuring proper ventilation and resisting slippery conditions. That’s how it enhances fire protection and lowers the need for regular maintenance.
- Concrete: What sets concrete apart is its thermal mass, which helps stabilize warehouse temperatures. And although this decking option offers strong support for large weights and machines, it lacks the ventilation advantage of open structures like bar grating.
- Resin composite: This decking option is perfect for warehouses that require a high load capacity of up to 2,000 pounds. The material also enhances skid resistance and is effective against moisture. Besides the functionality, resin composite is a wonderful choice for visual appeal.
- Wood: Wooden decking is not only simple to install but also eye-catching. The material also possesses pretty impressive strength to withstand heavy items. Yet, wood is prone to moisture damage, making it less durable in humid warehouse settings.
- Plywood: The material in question is lightweight yet robust, allowing for speedy installation and optimal space utilization. It’s also cost-effective and environmentally friendly.
- Particle board: Unlike wood, particle board is formed of wood fibers and glued with a 38-millimeter-dense resin. This low-cost material boasts high durability and is slip- and moisture-resistant. This helps expand its application in various situations.
- Laminated panels: These panels are an improvement to the plywood option above. By combining a plywood foundation with dense polyethylene on top, it enhances durability and becomes wear-resistant. They also block moisture, thus better safeguarding the mezzanine floor.
Assessing Mezzanine Floor Height
Mezzanine floor height is the vertical distance between the warehouse’s top surface and its ground floor. Typically, this crucial metric is expressed in feet or meters. Assessing this figure is important, as it influences many aspects of your inventory operations.
The first step before establishing a warehouse mezzanine floor is to figure out the minimum height for the raised platform. The suitable figure should be at least 14 feet (or 4.2 meters) from the platform’s floor to the warehouse ceiling. This number offers enough space and headroom for employees to travel conveniently when handling items.
Determining Mezzanine Floor Area
Regarding the mezzanine floor area, one common practice is to ensure it doesn’t surpass one-third of the entire facility footprint. For instance, in a 12,000-square-foot warehouse, the maximum mezzanine floor space should not be over 4,000 square feet.
This highest value often guarantees that your mezzanine floor meets construction requirements and safety norms. However, if you want a more spacious mezzanine platform, be sure to examine the regulations and request exemptions from the local authority.
Understanding Your Load Capacity
In addition to the minimum mezzanine floor height and the maximum mezzanine floor area above, you also need to evaluate your intended load capacity. A typical warehouse mezzanine can sustain about 50-100 kilograms per square foot. Of course, if you want to carry more stocks, you’ll need more reinforcement to support such heavy loads.
Additionally, you must assess the types of objects held on the mezzanine level. There’s a big difference between static and dynamic loads, with the latter case requiring more careful planning and design. Depending on your storage demands, the mezzanine floor height will require appropriate modifications.
Considering Used Mezzanine Floors
Installing a brand new mezzanine floor is not meant for every warehouse due to budget constraints. Therefore, purchasing second-hand mezzanine floors emerges as a potential alternative. When properly maintained and reassembled, these used structures can still provide years of reliable service while saving you a lot of money.
However, used mezzanines may not be a great match for your warehouse layout, affecting both the aesthetics and efficiency of the area. Compared to custom-built platforms, second-hand mezzanine floors might leave certain spots unused or awkwardly configured, thereby not maximizing your warehouse’s vertical space.
Anticipating Workflow Disruptions
Workflow interruptions are the last thing you want when employing mezzanine floors. There’re many elements that lead to these detrimental outcomes, and mezzanine floor height is one of them. That explains why determining this crucial metric requires your careful assessment of workflow implications.
Although having more extra room for inventory is great, building too high mezzanine floors is not a viable option since it eliminates the storage rooms below. These insufficient areas for staff and equipment can severely disrupt your warehouse operations.
Conclusion
Alright, let’s take your pencil and cross out the question “What is a mezzanine floor?” from your top-10-question list. If you manage to make it here, it’s pretty sure that you can answer the inquiry now.
The warehouse mezzanine floor is by far the most innovative and versatile solution to optimize the facility’s vertical space, thereby maximizing your inventory capacity. The beauty of this solution is that you don’t have to go down the expansion path, which is extremely costly.
