Construction Scaffolding System Galvanized Coupler Quick Lock System of Scaffolding

Ringlock Scaffolding is a modular, high-load, and versatile steel scaffolding system also known as Cuplock or Disc-Lock. It is characterized by vertical standards (uprights) with fixed steel rings (cups or discs) welded at regular intervals (typically 500mm or 1000mm). Horizontal ledgers and diagonal braces are connected using a unique wedge or blade that locks into these rings, creating a fast, secure, and robust node connection without loose nuts or bolts.

The Ringlock system offers significant benefits for large-scale, heavy-duty projects: Fast Assembly & Dismantling: The wedge-lock mechanism allows for tool-free or minimal-tool connections, drastically reducing labor time (up to 60% faster than tube-and-coupler). High Load Capacity: The rigid node connection provides exceptional strength and stability, making it ideal for heavy-duty support, shoring, and access. Intrinsic Safety: The wedge lock is non-detachable when under load, preventing accid

A complete system includes: Vertical Standards: Uprights with welded rings/cups. Horizontal Ledgers: Connect between standards using wedge heads. Diagonal Braces: For lateral stability, also using wedge connections. Base Jacks & U-Head Jacks: For height adjustment and leveling. Staircase Units, Guardrails, and Toe Boards. Special Components: Cantilever beams, ladder brackets, mobile bases.

Material: All primary components are made from high-strength steel tubing (Q235B or Q345B). Tube Diameter: Standard: 48.3mm OD. Heavy-duty versions use 60.3mm OD. Ring/Cup Spacing: 500mm is the international standard for vertical spacing, enabling modular planning. Surface Treatment: Hot-Dip Galvanized (HDG) is standard for maximum corrosion resistance and long life. Painted versions are available for cost-sensitive, short-term projects.

Assembly is quick and logical: Set Standards: Place standards with base jacks on a level foundation. Insert Ledgers: Slide the ledger's wedge head into the ring/cup on the standard. Lock: Use a hammer or mallet to tap the wedge down, locking it securely. A visual check confirms it's locked. Add Braces & Platforms: Insert diagonal braces in the same way to create a rigid bay. Install transoms and decking. Disassembly is the reverse, simply lifting the wedges with a tool.
