Used Silo Evaluation

A buyer in Philippines purchased a used silo without inspection. After disassembly, they found 30% wall loss in the lower shell. The repair cost exceeded the purchase price. That experience taught us: always inspect before buying used equipment.

Inspection checklist: Measure wall thickness at multiple points (focus on lower shell). Check coating condition and remaining life. Inspect all bolts for damage or corrosion. Verify structural integrity (no dents or distortion). Review maintenance history if available.

Relocation Planning

Bolted silo relocation: Document all connections before disassembly. Mark all components for reassembly. Photograph complex assemblies. Use proper lifting equipment. Protect coating from damage during handling.

Logistics considerations: Transport components without damage. Protect from corrosion during storage. Verify foundation at new site matches silo. Check local codes at new location. Plan for any missing or damaged parts.

Refurbishment Requirements

Common refurbishment needs: Coating repair or replacement (budget 30-50% of new coating cost). Bolt replacement if corroded (budget 10-20% of bolt value). Gasket replacement for all joints (budget 5-10% of silo cost). Component replacement for worn items.

Refurbishment process: Disassemble and clean all components. Inspect and sort (reuse, repair, or replace). Apply new coating to reused components. Replace all gaskets and worn hardware. Reassemble with new hardware as needed.

Cost-Benefit Analysis

Used silo cost components: Purchase price (30-50% of new). Transportation (5-10% of new). Refurbishment (20-40% of new). Installation (same as new). Total typically 60-100% of new silo cost.

When used makes sense: Temporary or short-term need. Budget constraints with acceptable risk. Standard sizes available immediately. Bolted construction for future relocation. Spare silo for backup capacity.

Frequently Asked Questions

Q: How do I know if a used silo is worth buying?

A: If refurbishment costs exceed 50% of new silo cost, buy new. Always get professional inspection before purchase.

Q: Can any silo be relocated?

A: Only bolted silos can be relocated economically. Welded silos are typically scrapped at end of service life.
