In the milling industry, block stacking is a double-edged sword. You save aisle space, but the bottom layer of your Soft Wheat Flour or Hog Starter feeds gets crushed into concrete-hard slabs. Mold grows where air cannot flow.
Derack's Metal Post Pallets turn your warehouse into a dynamic, vertical storage system without a single bolt drilled into your floor.
For operations managers at companies like GMC or similar milling giants, the balance between storage density and product integrity is a daily battle. Whether you are storing 25kg bags of Hard Wheat Flour or bulk sacks of Laying Mash, traditional wooden pallets fail in two critical areas:
The heavy duty stack racks solve this by changing the physics of storage. By using four steel posts to carry the load, the weight is transferred through the rack structure, not through your product.

In a feed mill producing diverse products—from Chick Booster to Duck Laying Pellets—block stacking creates a "buried inventory" nightmare. To get to the batch produced last week, you have to move everything in front of it. With portable stack racks, you can move an entire stack of 4 units at once, or easily rearrange rows to prioritize batches expiring soon (First-In, First-Out), drastically reducing spoilage rates.
Unlike wood, our galvanised stillages are non-porous and easy to sanitize. They do not retain moisture, effectively breaking the lifecycle of mold and insects. The wire mesh or steel sheet base allows for proper airflow around the sacks, keeping humidity levels consistent even in the center of a dense stack.
Delivering finished flour or feed to large commercial bakeries or distribution centers usually involves losing wooden pallets or dealing with expensive disposal. Derack systems are designed as returnable transport packaging.
Once your customer unloads the sacks, the empty racks don't need to take up a full truck's volume on the return trip. The posts are removed, and the bases nest into each other.
Fig 2. The Nesting Logic. A full truckload of product can be returned as empty racks in just 1/4 of the truck space.
| Feature | Traditional Wood Pallet | Derack Metal Post Pallet |
|---|---|---|
| Stacking Method | Product on Product (Crushing risk) | Frame on Frame (Zero product pressure) |
| Max Height | Typically 2 levels (Unstable) | 4 to 5 levels (Up to 25 ft) |
| Life Cycle | 10-15 trips (Breaks easily) | 5+ Years (Heavy Duty Steel) |
| Hygiene | High Risk (Mold, Splinters, Nails) | Food Safe (Washable, Galvanized) |
We understand that a sack of Siopao Flour behaves differently than a rigid box. That's why our racks feature:
1. Can these racks handle heavy bulk bags (FIBC) of animal feed?
Yes. Our standard portable stack racks are rated for 1,000 kg to 1,500 kg (approx 2,200 - 3,300 lbs) per rack. We can reinforce the base for heavier density loads typical in mineral mixes.
2. We have high humidity in our warehouse. Will these rust?
For food applications, we recommend a Hot-Dip Galvanized finish. This bonds zinc to the steel at a molecular level, providing superior corrosion resistance compared to standard powder coating, ensuring compliance with food safety audits.
3. Do I need to buy new pallets to use with these racks?
Not necessarily. The racks are designed to hold your existing standard wooden or plastic pallets. You simply place your loaded pallet inside the rack. However, many clients eventually switch to using the rack itself as the pallet to eliminate wood entirely.
4. How much space do they save when not in use?
The return ratio is typically 4:1 or higher. This means if you have seasonal fluctuations in flour demand (e.g., pre-Christmas peak), you can collapse the empty racks during low season to reclaim 75% of your floor space for other uses.
5. Can these be used for cold storage of yeast or specialty ingredients?
Absolutely. The steel structure is unaffected by freezing temperatures, unlike plastic which can become brittle. The open mesh design also allows cold air to circulate freely, freezing/cooling the product faster than solid stacking.
