Steel Lattice Beam 450mm
Steel lattice beams are scaffold bridging beams made of steel scaffold tubes. It is 450mm in depth (centre-to-centre height/distance between top and bottom), offering bridging in scaffolding for large-span required constructions, such as roofs, staging floors, and bridges.
Steel lattice beams feature top and bottom chords with a standard diameter of 48.3mm. Between the top and bottom chords, square steel tubes are welded on, serving as vertical and brace supports for the bridging beam. The design maximises the loading capacity of the steel scaffold bridging beams to take heavy-duty loads in construction, even for big spans.

Steel Lattice Beam Features
- Take heavy weights for a large-span scaffolding construction
- Easier to erect with prefabricated dimensions
- Enhance the safety and stability of the scaffolding structure
- Save scaffolding materials and accessories because of the heavy-duty and big-span function
- Durable with a long lifespan for repeated Use
- Compatible and Adaptable For All Scaffolding (including tubular scaffold and system scaffolding like ringlock, cuplock, etc)
- Can be secured by normal standard scaffolding couplers and fittings
Steel Lattice Beams
Steel lattice beams are designed as components of the ringlock scaffolding system initially. The standard sizes of the steel lattice beams are usually compatible with the ringlock bays(ringlock ledgers and transoms). Thus, the standard sizes of ringlock scaffold steel scaffold lattice beams are 2.25 m, 3.25 m, 4.25 m, 5.32 m, and 6.32 m.

How to Calculate Steel Lattice Beam Sizes In Ringlock Scaffolding System
Steel lattice beam sizes are the combination of ringlock scaffolding bays. The following are two examples of how the scaffold lattice beam size is calculated in the ringlock scaffold system.
5.32m Long Lattice Beams and Ringlock Bays | |
| No. | Bay Length |
| 1 | 1.57m + 2.07m +1.57m |
| 2 | 1×2.07m + 2×1.57m |
| 3 | 2×2.07m |
| 4 | 2*2.57m |
6.32m Long Lattice Beam Size and Ringlock Bays | |
| No. | Bay Length |
| 1 | 3×2.07m |
| 2 | 1 x 2.57m + 1*1.57m +1*2.07m |
| 3 | 2 x 2.57m |
| 4 | 2 x 3.07m |
Although steel lattice beams are initially designed for ringlock scaffolding, they do not have a specific ring system ledger and wedge locking mechanism, unlike ringlock girder beams. Thus, the scaffold bridging scaffold beams can be used in other scaffolding systems, including tube clamp scaffolding, cuplock scaffolding, and Kwikstage scaffolding.
In erection and construction, the scaffold lattice beams are secured to scaffolding structures using standard scaffolding couplers. While two steel lattice beams are connected by beam connectors (spigots), which have holes, and are secured to the scaffolding steel lattice beams using bolts and nuts, or span pins, cotter pins, and hinged pins.
Steel Beam VS Alloy Beams
450 scaffold bridging beams include steel lattice beams and aluminium(alloy) beams.
Steel lattice beams are made of steel structure, while alloy beams are made of aluminium scaffolding pipes.
| Items | Steel Lattice Beam | Aluminium Ladder Beam |
| Weight | Heavy | Light |
| Load | Bearing More Load | Less Load |
| Grade | S235/S355 | 6061 / 6082 |
| System | All Scaffold | All Scaffold |
| Diameter | 48.3mm | 48.3mm |
| Depth | 450mm | 450mm |
