A residential contractor in the United States was constructing a 15-story apartment tower with repetitive slab pours. Using traditional timber props and fixed-length supports, they faced three critical issues:
With 15 floors to pour, they needed a quick-adjust, reliable vertical support system that could streamline slab cycles.
The team switched to telescopic adjustable steel props with a pin-and-collar adjustment mechanism.
Key product specifications:
| Specification | Detail |
|---|---|
| Material | Q235 steel (48mm outer tube, 40mm inner tube) |
| Working range | 1.5m – 4.0m |
| Load capacity | 20–30 kN per prop |
| Adjustment | Pin holes + threaded collar |
| Finish | Hot-dip galvanized |
Key advantages on site:
| Metric | Timber Prop | Adjustable Steel Prop | Improvement |
|---|---|---|---|
| Shoring setup time per floor | Full day | Reduced by 1 day | Faster cycle |
| Load capacity | Variable | 20–30 kN | Consistent support |
| Reuse between pours | Limited | Collapsible & reusable | Lower cost-per-use |
Outcome: The contractor reported that switching to adjustable steel props cut shoring time by a full day per floor, accelerating the overall schedule significantly. The props' galvanized finish resisted moisture and rust, ensuring consistent performance across the 15-story build.
