The most common question we get from plants evaluating storage options is whether to go mobile or stay with static shelving. The honest answer is that it depends on three numbers — and most plants have not calculated any of them.
Variable 1: Floor space cost
What does a square foot of your facility actually cost you? Add lease or amortized purchase, utilities, insurance, taxes, and the opportunity cost of not using that space for production. The number is usually $80–$250 per square foot per year.
The higher this number, the faster mobile pays back. Mobile gives you back 30–60% of the floor space static would consume.
Variable 2: Inventory growth rate
If your sleeve and plate inventory is growing 5–10% per year (typical for a healthy converter), static shelving will run out of capacity within 3–5 years. The cost of expanding a static system later — or worse, replacing it — wipes out the upfront savings.
Mobile carriages add modular capacity without rebuilding the system.
Variable 3: Operator labor cost
Search time is real. Static systems with high inventory density become hard to navigate. Mobile systems with vertical storage and defined locations cut search time by 70–90%.
Multiply that against your fully loaded mounting room labor cost and the savings show up fast.
When static is actually right
Static storage is the right call for small operations (under ~300 sleeves), low inventory turnover, abundant floor space, and no growth expected. We sell plenty of static systems for these cases.
When mobile is right
Everyone else. The breakeven is usually under 24 months once all three variables are honestly accounted for.
