The Ringlock Layher ledger forms the horizontal backbone of modular ring scaffolding structures. By utilizing the modular rosette system, engineers can secure up to eight separate ledger and diagonal connections at a single planar junction node. Our Ringlock Scaffolding Ledger is fabricated to exact geometries where the forged ledger head contains a precision-punched wedge pin. When introduced into the rosette, the engineered wedge creates a force-locked, rigid node configuration.
This self-locking connection mechanism avoids the structural failures common to traditional bolt-and-coupler methods. Due to the exact angle configurations designed into the rosette (typically 4 large slots for diagonal braces and 4 small slots for ledger ends at perpendicular 90-degree lines), vertical alignment is automatically maintained, eliminating human alignment errors during high-speed field installation.
Technical Insight: Standard ledger nodes fabricated with Q355B low-alloy high-strength steel provide high bending moment resistance, enabling scaffolding systems to support heavy industrial masonry and industrial pipeline loads without experiencing permanent structural deformation.
Global industrial purchasing directors for petrochemical plants, marine offshore shipyards, and high-rise commercial structures face three primary supply chain vulnerabilities: consistency in metallurgical grades, long-term corrosion prevention, and regional regulatory compliance.
Zhuozhan Industry addresses these vulnerabilities by adhering to strict raw-material sourcing policies. Every batch of hot-dip galvanized steel undergoes chemical spectrographic analysis to ensure compliance with EN 10025 standards. Furthermore, our hot-dip galvanization process conforms directly to ISO 1461, ensuring an average coating thickness above 80 microns. This robust zinc barrier protects the underlying structural steel against highly corrosive maritime spray and chemical refinery atmospheres, delivering an extended operational lifespan of 15 to 20 years.
When considering operational cost-efficiency, the structural transition from legacy scaffold formats (such as tubular system scaffold and frame scaffolding) to Ringlock Layher ledger systems yields quantifiable field performance gains:
Fabricated using high-yield Q355B steel, our system supports a single-point node capacity of up to 10 metric tons, 1.5 times greater than typical modular cuplock assemblies.
Under realistic site conditions, a single standard erector can install 150 to 300 square meters of scaffold frame per day—a 300% to 500% speed increase over tube-and-clamp setups.
By maximizing the load-bearing potential of each standard and horizontal ledger, total equipment weight drops by 30% to 50% without compromising structural safety factor margins.

Steel pipes are cut to exact ledger dimensions with a tolerance of ±1mm, generating recyclable metallic offcuts.
Ledger ends are formed to receive forged heads. Noise levels are monitored under industrial workplace standards.
Automatic welding cells attach cast-steel ledger ends to the pipe. Smoke extraction units filter particulate matter.
Self-locking wedge pins are automatically riveted into the ledger heads, finalizing the safety mechanism.

Strategic supply agreements, comprehensive design capabilities, and global distribution logistics.
Our manufacturing base is close to major industrial shipping ports: Caofeidian Port, Jingtang Port, and Tianjin Port, reducing overland freight times and logistics costs.
Over 20 structural design engineers develop customized structural layouts for scaffolding, formwork, and shoring systems, ensuring compliance with local project requirements.
All scaffolding systems are manufactured to comply with EN 12810/12811, AS/NZS 1576, and ISO 9001 standards, with third-party mill test certifications available upon request.
As a key supplier to major state-owned and central construction groups, we have supported large projects like the Nanjing South Railway Station expansion.
Innovations in metallurgy, traceability, and structural engineering to improve safety and ease of installation on-site.
To balance safety with manual handling limitations, the industry is transitioning toward high-strength micro-alloyed steel. By incorporating trace amounts of niobium and vanadium, we can reduce ledger tube wall thickness from 3.25mm to 2.75mm while maintaining equivalent structural load-bearing performance. This reduces overall system weight by 15%, lowering transport emissions and worker fatigue during erection.
Large industrial projects require strict asset management and component tracking. Our next-generation ledger products can be fitted with integrated RFID tags welded into the cast head. This allows project teams to track the service history, cycle count, and safety certifications of each scaffolding component from delivery through to demobilization on site.
