Scaffold types
What is a system scaffold?
System scaffold is prefabricated scaffold whose components connect at fixed positions, usually through rosettes or cups welded to the standards, rather than being coupled anywhere along a tube.

</figure>The connections are predetermined, which is the whole trade-off. Assembly is faster and more consistent and needs fewer loose fittings, but the geometry is fixed to whatever the system allows.
Tube and fitting can be coupled anywhere along a tube, so it adapts to awkward buildings that a system cannot. Most firms run both and choose per job.
Systems are not interchangeable between manufacturers, and mixing components across systems is a real and common hazard — the connections may engage without achieving the designed performance.
What goes wrong on site
- Components from different systems mixed because they appear to fit.
- A system used on a building whose geometry it cannot follow, producing gaps and improvised infill.
- The manufacturer's instructions treated as optional.
