Industrial Scaffolding Selection Guide: 7 Critical Differences Between Ringlock & Frame Facade Scaffolding

In refineries, petrochemical plants, and power stations, choosing between Ringlock Modular Scaffolding (Layher Allround®) and conventional H-Frame Facade Scaffolding determines turnaround safety and schedule performance.

7 Core Engineering Differences

1. 3D Spatial Geometry: 8-way rosette connections (90° and 15°–120° angles) wrap around spherical tanks and pipe racks where 2D frames collide.
2. Load Classes (EN 12811-1): Ringlock supports Load Classes 4, 5, and 6 (300–600 kg/m²) and TG 60 shoring (60 kN/leg) vs. Class 3 (200 kg/m²) for facade frames.
3. AutoLock™ Wedge Safety: Instant gravity wedge locking approved under DIBt Z-8.22-939.
4. S460 MH Lightweight Steel: 12% lighter components with 24% higher bending strength.
5. 100m+ Wind Load Resilience: Certified under EN 1991-1-4 and TP-21-012.
6. Multi-Application Versatility: Suspended, cantilever, bridging, and circular tank scaffolds from one inventory.
7. 30% Faster Turnaround Execution: Eliminates tube-and-clamp modifications in congested process units.
