Galvanized Ringlock Scaffolding System Brace Head End
The ledger ends manufactured by EK Scaffolding are cast from ZG230-450 grade steel, achieving a minimum joint shear strength of up to 25 kN. Precision-machined using CNC technology, these ledger ends feature exact dimensions that ensure a precise fit with the rosette standards, thereby effectively minimizing structural sway. Welded using Golden Lion automated welding machines, they achieve full-penetration welds characterized by robust seams and uniform strength, completely eliminating the risks associated with missed or weak welds. This ensures that the scaffolding platform remains rigid and stable at all times, even in high-altitude working environments exceeding 50 meters.
Comparison of Manufacturing Processes for Ringlock Scaffolding Ledger Ends
| Category | Cast Steel Ledger End (Investment Casting) | Pressed Steel Ledger End (Stamped/Welded) | Forged Ledger End |
| Application Scenarios | Mainstream export model; currently the most common style in the international market, frequently used in high-quality engineering projects. | Economical model; commonly found in projects with extremely strict cost-control requirements. | Heavy-duty engineering model; utilized in heavy-support systems (e.g., bridges, power plants) where safety performance requirements are exceptionally rigorous. |
| Manufacturing Process | Utilizes the precision casting process involving either silica sol or water glass. | Formed by stamping thick steel plates using molds, which are then welded onto the ends of the steel tubes. | Produced by subjecting steel material to high-temperature forging. |
| Key Features | Smooth surface finish and extremely high dimensional accuracy, allowing for a nearly perfect fit with the Ringlock rosette. | Relatively simple structure and lighter self-weight. | Possesses a denser internal metal grain structure, with virtually no porosity or sand inclusions. |
| Advantages | High strength and excellent consistency; significantly enhances the torsional rigidity of the node connection. | Extremely low cost and short production lead times. | Exceptional toughness; performs outstandingly in extreme cold or high-impact environments without risk of brittle fracture. |
| Disadvantages | None | The contact area is typically smaller than that of cast ledger ends; more susceptible to localized deformation under heavy loads, resulting in slightly lower durability. | Highest production cost; the external finish is typically less refined than that of cast components. |

Ringlock Scaffolding Ultimate Guide 2026
Ringlock is a type of modular scaffolding. Modular scaffolding is a system scaffold with prefabricated interlock components without the need for scaffolding couplers and fittings to fix. Ringlock scaffolding systems include prefabricated parts of ringlock standard, ringlock ledgers, ringlock diagonal braces, etc, they can interlock each other, and no need for any scaffolding couplers in fixing.
Ringlock system is a group of ringlock scaffolding parts and components, including ringlock standard, ringlock ledgers, ringlock diagonal braces, decks, etc, used to form scaffold frames and towers for construction and shoring.
In the ringlock scaffolding, wedge pins are fixed on the ringlock ledgers and ringlock diagonal braces heads by rivets. It is used to fix ringlock system horizontals and braces between ringlock standard.
More than ringlock system scaffolding, cuplock system scaffolding, kwikstage system scaffolding, quick lock scaffold, crab shoring systems, and frame system scaffolding are modular scaffolds too.
