Growing Flowers, Growing Needs

When a leading flower distribution company in Miami, Florida, found itself bursting at the seams, they faced a familiar problem: limited space and soaring demand. With fresh-cut flowers coming in daily and no more square footage to spare, their options were limited. Expanding the building was too costly. Relocating meant operational disruption. But with creative thinking and the right partner, they found the perfect solution—not by building out, but by building up.

Enter the Two-Story Modular Mezzanine System—a custom-built storage solution from Panel Built, delivered through trusted partner Atlantic Rack.

This high-performance system completely transformed their existing warehouse, creating over 7,000 square feet of additional usable storage space. By going vertical with a two-level mezzanine, the flower company doubled their capacity without adding a single square foot to their building’s footprint.

Why Build Up, Not Out?

The Challenge

The client had a large volume of delicate, perishable inventory—fresh flowers arriving daily from growers around the globe. Their warehouse needed more room to organize, sort, and temporarily store this inventory before distribution to florists and retailers across the region.

But space was at a premium. Constructing an addition would be too expensive and take months. And moving wasn’t an option—they needed a solution that didn’t disrupt business.

A warehouse interior shows a large yellow metal mezzanine with stairs, surrounded by stacked boxes and pallets. Bright lighting highlights workers and construction materials scattered throughout the space.

The Solution

The answer came through vertical expansion—a two-level modular mezzanine that leveraged the height of their warehouse to dramatically increase storage capacity. Modular mezzanines offer a fast, flexible, and cost-effective way to multiply usable space without touching your building’s exterior walls.

With help from Atlantic Rack and Panel Built, this flower company turned an underutilized vertical area into a fully functional, code-compliant, and highly durable storage zone as part of a complete warehouse transformation strategy, learn more from our Logistics Arsenal for Warehousing and Logistics guide.

Engineering the Perfect Fit: Structural Features

Designing a mezzanine of this scale—two full stories and 33’ x 110’ in size—meant paying special attention to structural integrity, especially with the dynamic nature of warehouse activity and the delicate nature of floral products.

A large warehouse with tall yellow and gray metal shelving under construction, boxes and pallets organized on the floor, and workers in safety vests handling materials and equipment.
A warehouse interior with a partially constructed two-level mezzanine featuring bright yellow railings and stairs, surrounded by stacks of boxes and building materials.

Heavy-Duty Structural Beams

To support the system’s impressive 125 PSF load rating, extra-wide structural beams were selected. These beams not only accommodate the daily load of flower pallets, carts, and equipment but are designed for long-term durability and safety.

To anchor the system effectively, holes were cored into the existing concrete slab, allowing structural columns to be embedded deep into the foundation. This level of reinforcement ensures that the mezzanine remains stable for years to come, even under constant use.

Flooring that Performs: Durability Meets Practicality

Different warehouse zones demand different floor types—and this project was no exception. To serve various storage needs while ensuring safety and performance, the mezzanine combines two flooring systems:

Resin Deck Flooring

Ideal for general-purpose storage, resin decking is tough, cleanable, and resistant to the moisture and mess often found in flower operations.

Bar Grate Flooring

Where ventilation and spill-through are critical—especially in zones with water runoff or misting systems—bar grate flooring provides airflow, drainage, and additional load strength.

This hybrid flooring approach keeps the space flexible and functional for changing inventory and storage requirements.

Eight 6-Foot Double Swing Gates

Efficient movement of goods is critical in a busy floral warehouse. That’s why the mezzanine was fitted with eight 6’ wide double swing gates—strategically positioned to streamline loading and unloading.

Whether it’s forklifts transporting large pallets or employees moving carts of fresh flowers, these gates make it easy to access both levels safely and efficiently these gates make it easy to access both levels safely and efficiently—especially when combined with optimized pallet rack systems for faster picking and staging.

Safety and Compliance First

High Visibility Finishes

The mezzanine was finished in a combination of safety yellow and industrial gray powder coating, making it both eye-catching and highly resistant to wear and corrosion. The powder coating ensures the structure remains clean and professional-looking for years while providing visual safety cues for employees.

IBC Code Compliance

Every component of the structure—from railings to platforms to load ratings—was fully engineered and installed to meet the latest International Building Code (IBC) standards. In an industry where safety is paramount and inspections are common, having a code-compliant system is non-negotiable.
