Ringlock scaffolding, known for its distinctive rosette connection system, has transformed the construction industry over the past four decades. This modular scaffolding technology was invented by Germany’s LAYHER company in the 1980s as an upgraded product following cuplock scaffolding-10-15. Often called “daisy disc” or “rosette scaffolding,” it represented a significant leap forward in modular design and assembly efficiency.
Before Ringlock entered the global market, construction sites primarily relied on tube-and-coupler systems and the cuplock system developed by SGB in the 1950s. While cuplock offered speed for repetitive jobs, its fixed four-way connections limited flexibility-7. In the 1990s, after Ringlock’s initial patent protection expired, the system began spreading worldwide, undergoing adaptations to meet diverse regional standards and creating a modular scaffolding system-41-15.
The core innovation at the heart of Ringlock’s evolution is its rosette node — a circular steel plate up to 10mm thick, welded onto vertical standards at intervals, with eight holes for horizontal and diagonal connections-10. This allows up to eight multi-directional connections at a single point, enabling complex scaffolding configurations for curved facades, bridges, and industrial structures-1. The wedge-and-hammer connection requires no bolts, nuts, or spanners, significantly speeding erection while reducing lost parts and safety risks-1.
Since its introduction, Ringlock’s application scope has expanded dramatically. Originally designed for large concert lighting stands and background frames, it now serves high-rise buildings, bridge engineering, tunnel projects, shipbuilding, power plants, and oil refineries worldwide-5-3. Leading industry players like Doka have launched certified Ringlock systems, while the global ring lock scaffolding market was valued at US$2.42 billion in 2023 and continues growing steadily-16–.
Today, Ringlock scaffolding stands as the industry benchmark for modular flexibility, with tool-free assembly, exceptional load capacity, and hot-dip galvanized durability — a true testament to four decades of engineering evolution that continues to shape the future of construction safety and efficiency-1–.
