Longspan Shelving with Diamond Hole Uprights is a bolted medium-to-heavy-duty storage system designed for warehouse and industrial environments.
It combines high-strength steel uprights with a diamond hole positioning structure and bolted beam connections, delivering a rigid and stable shelving framework suitable for long-term industrial use.
Compared with light-duty shelving systems, this structure offers significantly improved load stability and deformation resistance, making it ideal for warehouses, workshops, and logistics centers.
Bolted Structure System
Uses bolt and nut connections for higher rigidity and long-term warehouse stability.
Diamond Hole Uprights
Improves beam positioning accuracy and reduces movement under heavy load.
Adjustable Levels
Shelf height can be adjusted by repositioning bolted beam connections.
Heavy Duty Design
Engineered for medium to heavy industrial warehouse storage applications.

Load Capacity (Engineering Reference)
Load capacity depends on beam span, steel thickness, and upright reinforcement. The following values are industry-standard engineering references for longspan shelving systems.
Light Duty
200 – 300 kg / level
Standard Warehouse
300 – 600 kg / level
Heavy Duty
600 – 1000 kg / level
Total bay capacity can reach 2000–4500 kg per bay, depending on configuration and span length.
Applications
Warehouse Storage
Ideal for bulk carton and SKU storage in distribution warehouses.
Manufacturing Plants
Suitable for storing tools, parts, and semi-finished goods.
Logistics Centers
Supports fast picking and organized inventory management.
Retail Stockroom
Efficient backroom storage for retail and supermarket supply chains.
Structural Comparison: Diamond Hole vs Butterfly Hole Uprights
The upright structure directly affects load stability, beam locking strength, and long-term warehouse safety. Below is a professional comparison of two common longspan shelving upright designs.
| Feature | Diamond Hole Uprights | Butterfly Hole Uprights |
|---|---|---|
| Structural Stability | High rigidity, strong locking | Moderate stability |
| Load Capacity | Medium to heavy duty (up to 1000 kg/level) | Light to medium duty |
| Beam Fixing Method | Bolted + precise alignment | Clip-in / hook connection |
| Long-term Performance | Stable under continuous load | May loosen under heavy use |
| Best Application | Industrial warehouses / logistics centers | Retail / light storage |
Installation Method
This bolted longspan shelving system is designed for stable, fixed warehouse installation. The assembly process is simple and suitable for on-site installation.
- Position uprights and ensure vertical alignment
- Fix beam connectors using bolts and nuts
- Tighten all structural joints for stability
- Install shelf panels (steel / plywood / mesh)
- Adjust shelf height according to storage requirements
No special equipment required. Suitable for warehouse assembly teams.
