Ringlock Scaffolding Lattice Girder

Engineered to international standards for safety, speed and durability on every job site.

Overview

The Ringlock Scaffolding Lattice Girder — often called a lattice beam — is a horizontal long-span member built from two parallel Ø48.3 chords linked by a diagonal triangular web. Where a standard ledger or even a truss ledger would deflect, the lattice girder carries heavy loads across wide gaps, so it is the beam of choice for bridging walkways, roads and ditches, supporting bridge decks and soffits, and carrying long-span working platforms in ringlock scaffolding.

Ringlock Scaffolding Lattice Girder - Triangular-Web Long-Span Beam

Key Features

  • Two-chord triangular lattice, far stronger than a flat ledger
  • Spans 2.07–8.52 m (6'10" to 28') in one piece
  • Bolted to ledgers/transoms with wedge clamps
  • No-spigot version for standard bay connections
  • Hot-dip galvanized Q345/S355, EN 12810 / AS-NZS 1576 / OSHA
  • Clears walkways, roads and ditches with a clean span

A lattice girder is the heavy-duty spanning element of a ringlock system. Its triangular web pattern distributes load efficiently to the two support points, letting it clear openings that no flat ledger could. Each end is bolted directly to the ringlock ledger (or to a transom) with the supplied wedge clamps, so the girder seats firmly on the bay. Options include spigoted ends that join two girders end-to-end for even longer spans, or the no-spigot version for standard connections. Like the rest of the system, the ringlock lattice girder is hot-dip galvanized Q345/S355 steel, built to EN 12810 / EN 12811, ANSI, AS/NZS 1576 and OSHA, with ISO 9001 quality and FOB Shanghai delivery from ACE SCAFFOLD.

A lattice girder is a deep, triangulated beam — the strongest horizontal member in the ringlock family for clear-span work. Where a flat ledger would simply deflect, the lattice girder holds its line across wide gaps and lets the scaffold bridge openings that no other member could.

Triangular-Web Long-Span Beam

Two Ø48.3 chords and a diagonal web form a rigid lattice that bridges far wider gaps than a solid ledger — ideal for spans from 2.07 m up to 8.52 m.

Bolted to the Ledger, Not the Rosette

The girder ends clamp onto the ledger with wedge bolts, so it sits above the bay as a secondary beam and lifts heavy loads clear of the standard rosette connection.

Where to Use It

Bridge decks and soffits, long-span formwork, stage and grandstand platforms, and any opening over walkways, roads or ditches where a clear span is required.

Frequently Asked Questions

Q
What is a ringlock lattice girder used for?
It is a long-span horizontal beam for ringlock scaffolding — used to bridge walkways, roads and ditches, support bridge decks and soffits, and carry heavy long-span working platforms that a standard ledger cannot clear.
Q
How does a lattice girder connect to the scaffold?
Each end is bolted to a ringlock ledger (or transom) with wedge clamps. The no-spigot version makes a standard connection; spigoted versions join two girders end-to-end for longer spans.
Q
What lengths are available?
The no-spigot series runs from 2.07 m (6'10") up to 8.52 m (28'), covering most bridge, soffit and long-formwork spans.
Q
Is the lattice girder stronger than a truss ledger?
Yes for clear span. A lattice girder is built as a deep triangular beam, so it carries heavier loads over wider gaps than a truss ledger, which is itself stronger than a flat ledger.
Q
What material and finish are used?
The ringlock lattice girder is hot-dip galvanized Q345/S355 steel, built to EN 12810 / EN 12811, ANSI, AS/NZS 1576 and OSHA, for site, coastal and offshore use.
Q
Can lattice girders be combined with other ringlock beams?
Yes. Lattice girders bolt to the same ledgers as standard and truss ledgers, so engineers can mix them — placing lattice girders only where the span demands and lighter members elsewhere — to control cost while meeting the design load.
