What is Scaffolding?

Scaffolding or staging is building equipment (platform) that is made temporarily and is used as a support for labour, materials and tools in every building construction work including maintenance and demolition work.

Safe scaffolding must be provided for all work that cannot be carried out safely by someone who stands on a strong and permanent construction, except if the work can be carried out safely by using stairs.

Scaffolds must be rigid, built of sound materials on good foundations and be well secured to the building or structure. In public places, scaffolds must be well lit or have warning lights fitted at the base.

Basic function of scaffolding:

  • As a safe working platform, workers stand on the platform and do the work easily and safely.

  • As a platform for placing material & logistic needed for the workers to carry out their job.

  • Scaffolds are used as a walking platform and to transport materials.

Jack Base:

It functions as a scaffolding foot that can be lowered to increase the height of scaffolding as desired.

U-Head Jack:

Works as a link between scaffolding with begisting logs. Similar to Jack Base, U-Head Jack can be lowered according to the desired height.


Serves as a foothold between frame scaffolding. Catwalk / Deck / Platform is used in scaffolding as access or accommodation for construction workers.



Serves as a connector if you want to add reinforcement pipes outside the main parts.
