Ring Lock Scaffolding System – 8-Way Connection, 150kN Capacity & 50% Faster Assembly for Construction Projects
[Product Overview
The Ring Lock Scaffolding System (disc lock / rosette scaffolding) is a next-generation modular access and support solution engineered for high-speed construction, heavy-load support, and complex structural geometry. Its patented 8-hole rosette design enables connections at 45° increments, allowing unprecedented flexibility for facade access, formwork falsework, bridge construction, and industrial maintenance.
For contractors seeking faster cycle times, lower labor costs, and zero loose parts, Ring Lock delivers up to 50% faster assembly than traditional systems while maintaining EN 12811 certification for global project acceptance.
【Key Differentiators – Why This Version？】
- 50% Faster Assembly– Wedge-lock connections require only a hammer; no nuts, bolts, or loose couplers. One worker can erect40–60 m² per day (compared to 20–30 m² with cuplock).
Zero Loose Components– Wedges are permanently attached to ledgers and diagonals, eliminating dropped parts, lost inventory, and safety hazards.
8-Way Connection (Every 45°)– Unlike cuplock (90° only) or frame scaffolding (fixed angles), Ring Lock supportsoctagonal towers, curved facades, and irregular support gridswithout custom fabrication.
Hot-Dip Galvanized Finish (≥65μm)– Provides20+ years corrosion protection; no painting, no rust maintenance, no deterioration of markings.
Highest Load-to-Weight Ratio– Q355B steel with 3.5mm wall thickness delivers150 kN per standardwhile keeping component weight manageable.
Full Compatibility– Interchangeable with major brands (PERI, ULMA, AT-PAC, Layher) – rosette spacing and wedge dimensions follow industry standards.
