Comparing Industrial Door Types: Spiral vs Sectional vs PVC
Choosing the right industrial door depends on usage frequency, insulation, speed, and budget. Here’s how our high-speed spiral door compares to traditional sectional and PVC roll-up doors:
1️⃣ Spiral Door (NHentrance HSD8022/HSD4322)
| Feature | Details |
| Opening Speed | 0.7–1.8 m/s |
| Panel | 43mm PU insulated aluminum |
| Drive System | Dual spiral guide (low friction, no noise) |
| Durability | 7+ years with low maintenance |
| Wind Resistance | National Level 3 / 3.5kPa |
| Best For | Exterior entrances, logistics zones, automotive |
Offers unmatched speed + insulation + aesthetics.
2️⃣ Sectional Door
| Feature | Details |
| Opening Speed | 0.2–0.5 m/s |
| Panel | PU foam, sandwich board |
| Drive System | Torsion spring & pulley |
| Durability | 4–5 years, moderate maintenance |
| Wind Resistance | Medium |
| Best For | Warehouse front doors, garages |
Cheaper upfront, slower operation.
3️⃣ PVC Roll-Up Door
| Feature | Details |
| Opening Speed | 0.8–1.5 m/s |
| Material | PVC curtain, optional window |
| Durability | 3–4 years (fabric wear) |
| Wind Resistance | Low to medium |
| Best For | Indoor partitions, dustproof zones |
Flexible but not ideal for strong wind or exterior use.
NHentrance Material Superiority
- 43mm aluminum door panel = better insulation (K ≤ 0.5 W/m²·K)
- CFC-free PU core, meets international thermal standards
- Optional polycarbonate vision windows (impact resistant)
- Stronger axle, QPQ-treated bearing shaft (anti-rust 3–5x better)
- Double spiral rail = zero contact = zero wear
Conclusion
If you are upgrading from a sectional or PVC door, a spiral door is your long-term investment — fast, quiet, durable, and energy-saving.
