Engineered to international standards for safety, speed and durability on every job site.
Overview
ACE SCAFFOLD manufactures ringlock scaffolding — also called ringlock system or modular ringlock — a multi-directional access and support system for building, construction, shipbuilding, offshore and industrial maintenance. Its 8-way rosette node accepts ledgers and diagonal braces at any angle and locks them with a hammer-driven wedge that stays tight under load and vibration, carrying 11.12 kN (2500 lbs) per connection. Built from hot-dip galvanized Q345/S355 high-strength steel with machine-welded (AWS D1.1) seamless joints, our ringlock scaffold erects about 30% faster than cuplock, cuts labor cost and needs little maintenance. As a trusted ringlock manufacturer we provide OEM/ODM service, ISO 9001 certification and FOB Shanghai delivery.

Ringlock scaffolding is a modular, multi-purpose system for access and support structures. It serves building facades, bridges, tunnels, power plants, shipyards, offshore rigs and industrial maintenance, and fits shoring, material loading platforms and formwork support. Erection is fast: a hammer-driven wedge locks every connection, so there are no loose bolts or pins to drop, and crews with basic scaffold training can build complex, multi-angle structures. The system cuts labor cost, handles easily and needs little maintenance. Components use hot-dip galvanized high-strength steel with integral wedge connectors, and a full accessory range is available — steel and aluminum planks, side brackets, toe boards, stairs, ladders, trap doors, swing gates and reinforced ledgers.
The wedge connection stays tight under load and vibration; ledgers and braces will not loosen. All connections fit rigidly and share load through one centre, keeping the structure safe even at great height. The ringlock node accepts up to eight ledger and brace connections; each connection carries 11.12 kN (2500 lbs) safely, and total ledger load must stay within the leg-load limit for the bracing used.
Vertical and horizontal tubes use 48.3 x 3.25 mm high-strength steel; ring plates are 10 mm thick; brace tubes use 48.3 x 2.3 mm high-strength steel with high-strength bolts. Every item is hot-dip galvanized for long service life. Standards and ledgers are machine-welded for clean, flat, seamless joints; welders follow AWS D1.1 for butt and fillet welding. Production runs in clear steps — material, cutting, welding, galvanizing, cleaning, packing — and parts ship in bundles.
Why Choose Ringlock
The 8-way rosette gives four small right-angle holes for ledgers and four large variable-angle holes for diagonal braces, so one node builds straight bays, curved or sloped structures and irregular facades alike. A single hammer assembles the whole system — no tools beyond the wedge, no loose fittings to lose — and because every joint is rigid and load-sharing from one centre, a ringlock bay stays square under wind and live load.
Load Capacity
Each rosette connection carries 11.12 kN (2500 lbs); standards are tested to high axial loads (up to about 151 kN at a 0.5 m bay), and steel plank decks are rated to 6 kN/m² (≈612 kg/m²) for shoring, loading platforms and formwork. Keep total ledger load within the leg-load limit for the bracing used.
Materials & Finish
Standards and ledgers are Q345/S355 (Q355B) high-strength steel; rosettes are 10 mm plates (Ø123 mm) and ledger heads are cast ZG230-450 with 25 kN shear resistance. Every component is hot-dip galvanized to ISO 1461 (zinc ≥80 µm), giving a 10–15 year service life on normal sites and 15–20 years in coastal and offshore service.
What is ringlock scaffolding and how does it work?
Ringlock scaffolding is a modular, multi-directional system built around a vertical standard fitted with welded 8-way rosettes. Ledgers and diagonal braces drop onto the rosette and lock with a hammer-driven wedge, so the whole structure assembles from one node at any angle without loose bolts or pins. It is used for access and support on buildings, bridges, shipyards, offshore rigs and industrial sites.
Q
Ringlock vs cuplock — what is the difference?
Both are modular systems, but ringlock uses an 8-way rosette with a hammer-driven wedge that locks ledgers and braces at any angle, while cuplock uses a cup-and-blade joint with fewer angle options. Ringlock is generally more flexible for curved, sloped or irregular structures and erects about 30% faster because there are no loose fittings to align.
Q
How much load can ringlock scaffolding carry?
Each rosette connection carries 11.12 kN (2500 lbs). Standards are tested to high axial loads — up to about 151 kN at a 0.5 m bay — and steel plank working decks are rated to 6 kN/m² (≈612 kg/m²), suitable for shoring, loading platforms and formwork. Keep total ledger load within the leg-load limit for the bracing used.
Q
What material and finish is used?
Standards and ledgers are Q345/S355 (Q355B) high-strength steel; rosettes are 10 mm plates (Ø123 mm) and ledger heads are cast ZG230-450 with 25 kN shear resistance. Every component is hot-dip galvanized to ISO 1461 (zinc ≥80 µm), giving a 10–15 year service life on normal sites and 15–20 years in coastal and offshore service.
Q
How fast is ringlock to erect and dismantle?
A single hammer locks every connection, so erection and dismantling are fast and need no special tools or loose fittings. Crews with basic scaffold training can build multi-angle structures quickly, which typically cuts on-site time by about 30% compared with cuplock and reduces labor cost.
Q
What applications is ringlock scaffolding used for?
It is used for building facades, bridges, tunnels, power plants, shipyards, offshore rigs, shipbuilding, event staging, shoring and formwork support — anywhere a modular, multi-angle access or support structure is needed.
Q
Which standards and certifications does it meet?
ACE SCAFFOLD ringlock scaffolding is built to EN 12810 / EN 12811, ANSI/SSFI SC100, AS/NZS 1576 and CSA, meets OSHA job-site rules, carries CE marking and is supplied under ISO 9001 quality with FOB Shanghai delivery.
Q
Can ringlock components mix with other brands?
No. The 8-way rosette and wedge-lock are proprietary to ringlock, so components are not compatible with cuplock, kwikstage or tube-and-coupler systems. Always use matched ringlock parts from one manufacturer and follow local safety regulations.
Q
What are the key safety rules on site?
Keep base jack exposure within 300 mm, brace every bay, maintain a 4:1 stability ratio for free-standing towers, fit guardrails, swing gates and toe boards on open edges, and require PPE (hard hat, harness, boots). Inspect components before and after use and replace damaged parts promptly.
Q
How many rosettes does a 10-feet vertical have?
Ringlock standards are welded with rosettes at a 0.5 m (500 mm) pitch, so a 10-foot (3.05 m) ringlock vertical carries 6 rosettes — one every 0.5 m along the tube. Always confirm the exact rosette count and spacing against the stamped drawing for the bay height you plan, because the number of rosettes per standard can vary slightly by length and by manufacturer.
