Ringlock scaffolding is a modular system that is part of the broader category of scaffolding systems, which also includes Cuplock and Kwikstage systems. Ringlock scaffolding, also known as pin lock scaffolding, rosette scaffolding, ring lock scaffolding, or multidirectional scaffolding, is constructed from pre-fabricated components such as horizontals, vertical standards, diagonal braces, and planks, etc. This system is designed for ease of assembly, disassembly, and transportation, making it a popular choice for various construction and industrial applications.
There are many different parts in the ringlock scaffolding, following is the introduction of some basic parts:
The ringlock verticals, also called standards, are the backbone of the Ringlock system, providing the primary support structure. They are typically made from high-strength steel tubes with welded rings (scaffolding rosettes) at intervals of 500mm. The tubes are mostly Q355 material grade. Lengths come in 0.5m, 1m, 1.5m, 2m, 2.5m, 3m, 4m.
Horizontals, also known as ledgers, are used to connect vertical standards. They come in two types: O Type and U Type, each designed to fit specific configurations within the Ringlock system.
O type ledger is made of 48.3 x 3.2mm tubes, Q235 or Q355 material grade.
U type ledger is made of a special type of U profile.
Different casting ledger heads are used to adapt to steel tubes and U profiles.
Ringlock scaffolding O type ledgers come in sizes of 0.73m, 0.9m, 1.09m, 1.29m, 1.57m, 2.07m, 2.57m, 3.07m, or other custom lengths. In the USA, lengths come in 2’2”, 2’10”, 3’, 3’6”, 3’10”, 5’2”, 6’, 7’, 8’, 10’, etc.
Ringlock scaffolding U type ledgers come in sizes of 0.73m, 1.09m, 1.29m, 1.57m, 2.07m, 2.57m, 3.07m, or other custom lengths.
U type ledger is more used in Layher type ringlock scaffolding. U type hook steel plank is designed for this type of ledger.
O type U type
Diagonal braces are used to provide lateral support and stability to the scaffolding structure. They help prevent sway and ensure the structural integrity of the scaffolding. They are typically made from 48.3 x 2.5mm steel tubes, punched at two ends and with casted diagonal heads at both ends.
Ringlock scaffolding diagonal braces come in sizes of 0.73m x 2m, 0.9m x 2m, 1.09m x 2m, 1.29m x 2m, 1.57m x 2m, 2.07m x 2m, 2.57m x 2m, 3.07m x 2m, or other custom lengths. The bay height is usually 2m.
Planks serve as the working platform for workers. They are available in different types, including O Type, U Type, and American Type, to accommodate various load-bearing requirements and project needs.
The width comes in 190mm, 228mm, 240mm, 320mm, etc.
Lengths often match the lengths of the ledgers for the best fit.
O type U type American type
The base collar is used to connect the vertical standards to the base jack, providing a stable foundation for the scaffolding structure.
The base jack is an adjustable component that allows for leveling the scaffolding on uneven surfaces. It provides the initial support for the vertical standards.
The diameter of the threaded rod is usually 38mm, which is compatible with 48.3mm ringlock vertical tubes.
The leveling jack can be made with round or square threads.
Side brackets are used to provide additional support and stability to the scaffolding structure, especially at corners and intersections. They come in one, two, and three-board configurations.
Double ledgers are used to increase the load-bearing capacity of the scaffolding. They consist of two horizontal beams connected by tubes or plates, forming a truss-like structure. Ledger heads are welded at both ends for connection use.
U bridging ledgers are made of U type profile and are used to connect vertical standards at different levels, providing additional support and stability. They are more commonly used in Layher type scaffolding.
Aluminum or stairways are used a lot in ringlock system scaffolding for access use.
The scaffolding rosette is a welded ring on the vertical standards, featuring multiple holes that allow for the connection of horizontals and other components.
The ledger head is a component that connects the rosettes of the vertical standards to the horizontals, ensuring a secure and stable connection.
Ledger head O type Ledger head U type (for U transoms)
Brace heads are casting steel end that is assembled to two ends of the diagonal tube. It connects to ringlock scaffolding vertical rosette holes by wedges.
The rosette clamp is used to secure ringlock ledgers and braces for strengthening the scaffolding system, providing a tight and stable connection.
Lattice beams are used to provide additional support and rigidity to the scaffolding structure, especially in high-load applications.
Steel ladders are integrated into the scaffolding structure to provide safe access to different levels of the scaffolding.
The length comes in 2m, 3m, 4m, etc.
The horizontal rungs are made from anti-slip tubes.
Hot-dip galvanization involves immersing the steel components in a bath of molten zinc. It is the best way to the protect the scaffolding surface andwithstand various weather conditions and physical impacts. It can extend the life of the steel pipe to 15-20 years.
Powder coating involves applying a dry powder to the metal surface and then curing it under heat to form a hard, durable finish. It is highly resistant to chipping, scratching, and fading, making it suitable for long-term use. Nowadays, we kindly give up the surface treatment of painting, to protect the environment. Powder coating becomes a good option, because it is more eco-friendly than painting, and much cheaper than hot dip galvanization.
The modular design of Ringlock scaffolding (with less components than other system scaffolding) allows for easy assembly and disassembly, making it highly versatile and adaptable to various construction needs.
Ringlock components are typically made from high-strength steels such as Q355 and Q235, ensuring durability and safety. The system can support significant loads, making it suitable for heavy-duty construction projects.
Hot-dip galvanized surface finish also guarantees the long-life span of the scaffolding system.
The above features also make the ring lock scaffold require less maintenance.
The use of diagonal braces and other support components such as base jacks, ensures the stability and safety of the scaffolding structure. This is crucial for preventing accidents and ensuring a safe working environment.
When erecting the ringlock scaffold, all you need is a hammer, to fix the wedge in the holes of the vertical rosette. This quick and easy assembly of Ringlock scaffolding components reduces construction time and labor costs, improving overall project efficiency. Research indicates that Ringlock saves 53% of time compared to Tube and Clamp Scaffolding when erecting.
Due to the special design and the high efficiency of the ringlock scaffolding, fewer scaffolding clamps and fewer scaffolders will be needed for the construction job.
While the initial investment in Ringlock scaffolding may be higher, the system's durability, reusability, and energy efficiency can lead to long-term cost savings.
Ringlock scaffolding is used in a wide range of applications, including:
Construction
High-rise buildings, bridges, dams, and other large construction projects.
Industrial Maintenance

Setting up Ringlock scaffolding involves several key steps:
Planning and Inspection
Before assembly, inspect all components to ensure they are in good condition and free from damage.
Base Jack Installation
Install the base jack on a level surface and adjust it to ensure stability.
Vertical Standards Assembly
Connect the vertical standards to the base jack using the base collar. Ensure the standards are vertically aligned and securely fastened.
Horizontal Ledgers Installation
Attach the horizontal ledgers to the vertical standards. Ensure the ledgers are securely fastened and aligned correctly, making sure the wedges are tight in the position.
Diagonal Brace Installation
Install diagonal braces between the vertical standards and horizontal ledgers to provide lateral support and stability. Ensure the wedges are tight in position.
Plank Installation
Place the planks on the horizontal ledgers, ensuring they are securely hooked and provide a stable working platform. Make sure the locks are in position.
Additional Components
Install additional components such as side brackets, double ledgers, and U bridging ledgers as needed to enhance stability and load-bearing capacity.
Final Inspection
Conduct a final inspection to ensure all components are correctly installed and securely fastened. Check for any signs of instability or damage.
