Scaffold Planks

scaffold is a makeshift structure temporarily created to support construction workers and materials during construction. It has been in use since time immemorial.


Several types of scaffolding are used today. There are pre-constructed, modular system of pipes or tubes, made from different kinds of materials such as steel, aluminium, or even wood or bamboo as commonly used in Asia.

Safety in Erecting Scaffold Planks

Scaffoldings are critical to the success of the construction. Its structure must be ensured to be safe and secure. Therefore, guidelines have been created in order to verify the safety of scaffolding.


Scafflink Australia strictly follows these rules and regulations. Every scaffolding specialist must keep in mind that:

  • Inspections and testing must first be held on all scaffold planks.
  • To create a work surface, there should be at least two lumber scaffold planks standing side by side.
  • Scaffold planks must completely cover the area between front and rear vertical supports or the rear guardrail.
  • Scaffold planks should be verified and secured against any movement in any possible direction, including uplift.
