Ringlock Scaffolding Manufacturer & Supplier in India
Sun Corp manufactures ringlock scaffolding systems in hot-dip galvanised mild steel for infrastructure, industrial, and high-rise construction projects. Supplied from our Jeedimetla, Hyderabad facility to construction sites across India — including metro rail, bridge, power plant, and commercial building projects.
What Is Ringlock Scaffolding?
Ringlock scaffolding is a modular access system where ledgers and diagonal braces connect to a rosette plate welded on the standard at fixed intervals. Each rosette has 8 connection points — 4 for ledgers and 4 for diagonal braces — allowing multi-directional connections at a single node. One hammer tap locks the wedge pin into position, creating a rigid, stable joint without loose clamps or fittings.
Ringlock vs Cuplock — Key Difference
Cuplock uses a cup-and-wedge system with 4 connection points per node, making it fast for straight, repetitive structures. Ringlock uses a rosette with 8 connection points, making it superior for curved geometries, circular tanks, bridge piers, and complex industrial structures where multiple bracing angles are required.

Where Ringlock Scaffolding Is Used
Infrastructure Projects
Ringlock scaffolding is the system of choice for metro rail viaducts, ROB bridges, flyovers, and cooling towers — where curved geometry and multi-directional bracing are required. The 8-way rosette allows angle changes without losing structural integrity.
Industrial Plants
Refineries, power plants, and petrochemical facilities use ringlock systems for maintenance access around circular tanks, pressure vessels, and boiler structures. The galvanised finish withstands industrial environments with chemical exposure.
High-Rise Construction
For perimeter access on towers above 30 floors, ringlock provides superior lateral stability and integrated stair tower capability compared to cuplock systems.

Frequently Asked Questions — Ringlock Scaffolding
What is the load capacity of ringlock scaffolding standards?
Sun Corp ringlock standards in 48.3mm x 3.2mm S355 steel support vertical loads up to 60 kN per standard depending on height and bracing configuration. Load calculations should be done by a qualified structural engineer for each project.
What is the difference between ringlock and cuplock scaffolding?
Ringlock uses an 8-way rosette connection allowing multi-directional bracing — ideal for curved and complex structures. Cuplock uses a 4-way cup connection for fast erection on straight, repetitive layouts. Ringlock components cannot be mixed with cuplock components.
Does Sun Corp supply ringlock scaffolding for infrastructure projects?
Yes. Sun Corp supplies ringlock systems to metro rail, bridge, ROB, and power plant projects across India. We have supplied to L&T, Adani Power, BHEL, and NTPC project sites.
What surface treatment does Sun Corp use on ringlock components?
All ringlock components are hot-dip galvanised with a minimum 85-micron zinc coating, providing corrosion resistance for outdoor and industrial environments. Powder-coated finish is also available on request.
Can ringlock scaffolding be used for circular structures like cooling towers?
Yes. The 8-way rosette allows ledgers and braces to connect at multiple angles, making ringlock the preferred system for circular tanks, cooling towers, silos, and bridge piers where curved geometry is required.
