Demountable Post Pallets

For warehouses managing bagged goods like flour, animal feeds, or agricultural products, floor stacking creates costly problems: crushed products, wasted vertical space, and chaotic inventory management. Our heavy-duty portable stack racks provide an immediate solution, allowing you to safely stack 4-5 layers high, protect your inventory, and transform your floor space into valuable cubic storage.

The Hidden Costs of Floor Stacking Flour and Animal Feed

For industries producing bagged goods, such as flour mills and animal feed manufacturers, the traditional method of floor stacking (block stacking) seems like a simple, low-cost storage solution. However, this approach conceals significant operational inefficiencies and direct financial losses. The core problem lies in the inherent limitations of the goods themselves; products like swan flour or layer mash for chickens are not designed to be structural supports.

Direct Product Damage and Revenue Loss

When bags are stacked directly on top of each other, the bottom layers bear the full weight of the stack. This immense pressure leads to several negative outcomes:

Wasted Vertical Space and Inefficient Operations

A warehouse's most valuable asset is its cubic volume, yet floor stacking only utilizes a fraction of it. The height of a stack is limited by the crush strength of the bags, typically capping out at a low level. This means managers are paying for expensive overhead space they cannot use.

Furthermore, block stacking enforces a rigid Last-In, First-Out (LIFO) inventory system. Accessing a specific batch or SKU, such as hog starter feeds, located at the bottom or back of a stack requires the time-consuming and labor-intensive process of moving every other pallet on top of it. This double-handling increases labor costs and the risk of product damage with every move.

How Portable Stack Racks Revolutionize Bagged Goods Storage

The solution is to shift the load-bearing responsibility from the product to a dedicated steel structure. A portable stack rack, also known as a post pallet or pallet stillage, is essentially a heavy-duty steel pallet with removable corner posts. This simple but powerful design fundamentally changes warehouse dynamics.

From Product-Bearing to Structure-Bearing

With industrial stacking racks, a pallet of bagged goods is placed inside the rack's base. When another rack is stacked on top, its legs rest securely on the four corner posts of the unit below. The weight is transferred directly through the steel frame to the floor. The bags on the bottom layer experience zero compression from the loads above them. This single change eliminates crush damage and allows you to safely stack fragile or irregularly shaped items as high as your forklifts can reach.

Unlock Vertical Space and Maximize Density

By creating a self-supporting modular structure, stack racks allow warehouses to utilize their full vertical height. It is common to stack units 4 or 5 high, instantly increasing storage capacity by 400-500% on the same floor footprint. This transforms unused overhead space into valuable, revenue-generating storage and can delay or eliminate the need for costly warehouse expansion or off-site storage.

Achieve 100% Selectivity and Operational Flexibility

Unlike block stacking, every stack rack is a discrete, movable unit. A forklift can access any pallet in any position without disturbing the ones above, below, or next to it. This provides the 100% selectivity of traditional pallet racking but without the need for fixed aisles. When inventory levels change with seasonal demand, these portable stack racks can be moved, reconfigured, or, when empty, dismantled and nested together to open up floor space for other operations like cross-docking or order fulfillment.

The Tangible Impact on Your Bottom Line

Implementing a stack rack system is not just an equipment upgrade; it's a strategic move that delivers measurable returns by addressing the core pain points of bagged goods storage.

Drastically Reduced Product Write-Offs

By preventing compression damage, the primary cause of inventory loss is eliminated. This directly translates to higher yield, less waste, and increased profitability. For food-grade products, protecting the integrity of the packaging also reduces the risk of contamination, ensuring compliance with health and safety standards.

Streamlined Warehouse Workflow

The unitized nature of stack racks optimizes material handling at every stage. During inbound receiving, pallets can be immediately placed into racks and stacked, drastically reducing unloading times. For outbound shipping, the exact pallet needed can be retrieved and loaded directly onto a truck without redundant handling, improving order accuracy and fulfillment speed.




Frequently Asked Questions

What exactly is a stack rack?

A stack rack is a modular, portable storage solution consisting of a steel base and removable corner posts. It allows you to stack pallets of goods vertically without the items themselves bearing any weight. This protects products from damage and maximizes warehouse storage density.

How much warehouse space can I realistically save?

By stacking 4 to 5 units high, you can increase your storage capacity by 400% to 500% on the same floor area compared to single-level floor stacking. It turns your vertical, unused air space into productive storage.

Are stack racks safe for heavy loads like bags of flour or cement?

Absolutely. Heavy duty stack racks are engineered from high-strength steel (like Q235) and are designed to support thousands of pounds per unit. The weight is transferred through the steel frame, making it an extremely safe and stable method for heavy, palletized goods.

Can I use my existing forklifts with these racks?

Yes. Stack racks are designed with four-way fork entry pockets, making them fully compatible with standard warehouse forklifts and pallet jacks. No special equipment is required for handling.

How do stack racks differ from permanent pallet racking?

The key difference is flexibility. Permanent racking is bolted to the floor, creating fixed aisles and a rigid layout. Stack racks are portable and modular, allowing you to change your warehouse layout in minutes to adapt to seasonal inventory changes or new operational needs. When empty, they can be knocked down and stored in a fraction of the space.
