Bundling, Forklift Stillage & Container Top-Up Specs
All six lengths up to 820 cm load straight inside standard 40HC ocean containers (12.03 m internal length) and 13.60 m trailers alongside scaffold frames.
Structural Engineering Details, Fleet Compatibility & Field Performance
Bridging Active Truck Gates, Storefronts & Garage Ramps
When ground-level garage ramps, hospital emergency bays, or retail storefronts must remain unobstructed during facade renovation, twin SM-A171 galvanized steel lattice beams span the opening and transfer multi-story upper scaffold loads onto flanking double-leg towers.
Temporary Weather Roofs & Suspended Scaffolds with SM-A481 Aluminium Beams
Weighing just 24.8 kg at 6.20 m (versus 62.0 kg in steel), the SM-A481 aluminium lattice beam is the premier choice for temporary weather-protection roofs, glass-atrium maintenance bridges, and high-altitude cantilevered staging.
Universal Ø48.3 mm Chords & SM-A653 Spigot End-to-End Splicing
Both steel and aluminium series use Ø48.3 mm O.D. top and bottom chords, accepting standard EN 74 couplers anywhere for lateral compression-chord bracing. Two beams can also be spliced end-to-end using bolted SM-A653-048000 internal spigot connectors (2.4 kg).
