An industrial contractor in Jakarta, Indonesia, was building a 15,000 m² logistics warehouse with 12-meter-high concrete roof beams and a 200mm thick suspended slab. They faced three major issues with traditional tube-and-clamp scaffolding:
Slow assembly — 10 workers took 8 days to erect falsework for a single bay
Inconsistent connection quality — clamps loosened under vibration, requiring constant re-tightening
High material loss — loose clamps and fittings were frequently misplaced or stolen
They needed a faster, safer modular system with minimal loose parts.
We supplied a Cuplock scaffolding system — named for its cup-and-blade connection mechanism.
| Specification | Detail |
| Material | Q235 steel, hot-dip galvanized |
| Vertical standard | 48.3mm OD × 3.2mm |
| Cup spacing | 500mm intervals |
| Connection | Fixed bottom cup + sliding top cup + blade end |
| Max leg load | 70–90 kN |
How it works: Insert ledger blade into bottom cup, slide top cup down over blade, hammer tight — one strike per connection.
Key advantages:
No loose clamps (cups are pre-welded, blades forged onto ledgers)
Vibration actually tightens the connection (no re-tightening needed)
Only a hammer required — no wrenches or bolts
| Metric | Tube & Clamp | Cuplock | Improvement |
| Installation time per bay | 8 days | 5 days | 40% faster |
| Workers required | 10 | 7 | 30% less labor |
| Loose part types | 8+ | 2 (standards + ledgers) | Minimal loss |
| Re-tightening needed | Frequent | None | Zero maintenance |
Outcome: Warehouse roof completed 3 weeks ahead of schedule. Contractor saved approximately 4,800 USD in labor and reported 95% material recovery (vs. 70% for tube-and-clamp).
For industrial warehouses and concrete slab support, Cuplock delivers:
Switching to Cuplock scaffolding helped this Jakarta contractor cut installation time by 40%, eliminate re-tightening, and reduce material loss. For warehouse falsework and general construction, Cuplock is a reliable, cost-effective choice.
