Storage Mezzanines

Is your building losing storage space for supplies and equipment and you feel you need to expand in order to accommodate everything? Storage mezzanines offer a great solution for creating a new area for storage without losing any existing floor space. Any facility that needs to improve efficiencies by improving organizing can benefit. This includes manufacturing and distribution facilities, hospitals, hotels, hangars and more.

Utilize Ceiling Space to Create New Storage Areas

You want your business to grow, but sometimes growth and progress can come at a very sudden pace. When your capacity begins to outgrow your present means, expansion or relocation may not be immediately viable, nor the most optimal solution.

Utilizing Porta-King’s storage mezzanines and platform systems can create new storage options by building up and repurposing unused air space. The mezzanine system is constructed with structural steel framework designed to support raised platforms that create safe, secure space above your existing floor.

Factories where floor plans are typically dedicated to large machines and stores of materials often don’t consider valuable vertical space, and when you consider the other options of expansion or relocation, building up with storage mezzanines is the cost and time effective solution your business needs.

Storage mezzanine platforms allow you to create new areas above your workspace without the need to construct entirely new areas of your building. Since you will be utilizing unused ceiling space, you can continue to use the space underneath for personnel and equipment.

Porta-King structural steel mezzanines are a cost efficient way to easily create additional space for storage or manufacturing by utilizing existing ceiling space inside new or existing buildings. Additional floor space is created by going up, not out, saving you the considerable cost of new construction. The prefabricated design also saves time since all components arrive prefabricated and ready for immediate installation.

Unlike many of our competitors, we’ll supply you with a truly prefabricated mezzanine system. All of our connecting hardware is pre-welded onto the structural components prior to shipping. Many of our competitors call their mezzanines prefabricated, but that just means the various components used to construct their mezzanines are prefabricated prior to shipping. Unlike a Porta-King mezzanine, this doesn’t always mean these components arrive welded to the structural components and ready to be mechanically fastened together.

This video demonstrates the speed in which our mezzanines can be installed. This 18′ wide by 48′ long mezzanine, including our single piece, sectional guard rail was completed by a two man crew in just 2 days.

Note the ease with which our 6′ wide sliding gate operates. Heavy-duty steel construction ensures years of trouble free service. Other mezzanine gate options are also available.

Fast, Safe Construction Saves You Time & Money

Prior to shipping, our storage mezzanines are designed in-house by our engineers, which enables us to ship pre-engineered structural components to you that are ready for installation, thereby reducing the cost of construction and giving you a truly prefabricated mezzanine.

Frequently Asked Questions

One of the significant advantages of choosing a reputable mezzanine or tower provider is the potential to minimize or eliminate the need for on-site welding during the installation process. Many leading providers, like Porta-King, design their mezzanines and towers to be completely bolt-together constructions. This means that all the structural components are prefabricated and pre-drilled, allowing for a seamless assembly process that requires no welding.

By eliminating the need for welding, you can significantly reduce the time and cost associated with installation. Welding requires specialized equipment, skilled labor, and additional safety precautions, all of which can add to the overall project expense. In contrast, a bolt-together system can be installed quickly and efficiently, often using only basic hand tools and a smaller crew. This not only saves hundreds of dollars in installation costs but also minimizes disruption to your facility and allows you to start using your new mezzanine or tower sooner.

When evaluating potential mezzanine or tower providers, be sure to inquire about their installation process and whether they offer a bolt-together solution to maximize your savings and efficiency.

Column base plate pressure is a critical factor to consider when installing a mezzanine, as it determines the amount of load that will be transferred to the concrete foundation beneath the structure. The base plate pressure is calculated by dividing the total load on each column by the area of the base plate. If the resulting pressure exceeds the capacity of the existing concrete slab, it may be necessary to modify the foundation to ensure proper support for the mezzanine. This can involve cutting the existing concrete and pouring new footings to distribute the load more effectively.

By assessing the column base plate pressure early in the planning process, you can identify any necessary foundation modifications and factor them into your project timeline and budget. Failing to address this crucial aspect of mezzanine installation can lead to structural issues and safety hazards down the line. Therefore, it’s essential to work with an experienced provider who can accurately calculate the base plate pressure and recommend the appropriate foundation solutions for your specific mezzanine installation.

The dead load of a mezzanine refers to the weight of the structure itself, measured in pounds per square foot (psf). This includes the weight of the structural components, such as the steel beams, columns, and decking, as well as any permanent fixtures or equipment that are integral to the mezzanine. The dead load is a constant value and does not change based on the usage of the mezzanine. In contrast, the Design Live Load (DLL) accounts for the weight of any additional items placed on the mezzanine, such as inventory, machinery, and personnel. The DLL is determined by the intended use of the mezzanine and can vary depending on the specific application.

When designing a mezzanine, engineers must account for both the dead load and the DLL to ensure that the structure can safely support the total load without compromising its integrity. By understanding the difference between dead load and DLL, you can make informed decisions about your mezzanine installation and ensure that it meets your load-bearing requirements.

DLL, or Design Live Load, is a critical factor in the engineering and construction of mezzanines and towers. It refers to the maximum weight, measured in pounds per square foot (psf), that the structure is designed to support safely. This load includes the weight of any equipment, materials, and personnel that will be present on the mezzanine or tower during normal use. The DLL is determined by the intended use of the structure and is a key consideration in the design process.

By specifying the appropriate DLL, engineers can ensure that the mezzanine or tower is built to withstand the expected loads and maintain its structural integrity over time. When planning for a mezzanine or tower installation, it’s essential to accurately assess your load requirements and communicate them to your provider to ensure that the final structure meets your specific needs and safety standards.

When planning for a mezzanine installation, two essential height measurements to consider are the top of deck height and the clear height. The top of deck height refers to the distance from the existing facility’s finished floor to the top surface of the mezzanine floor. This measurement is crucial for determining the overall height of the mezzanine and ensuring that it fits within the available vertical space.

On the other hand, the clear height is the distance from the existing facility’s finished floor to the lowest point on the underside of the mezzanine structure. This measurement is important for understanding the usable space beneath the mezzanine and ensuring that it can accommodate any necessary equipment, storage, or personnel. By carefully considering both the top of deck height and clear height, you can ensure that your mezzanine installation maximizes the available space and meets your specific operational requirements.
