Scaffold parts: what they are called and how many you need
A facade scaffold is built from the same part types whatever the brand: standards or frames, ledgers, decks, guardrails, toeboards, braces, base jacks and wall ties. Here is what each part does, and how many ScaFix calculates for the example house with Layher Blitz, Layher Allround and PERI UP. 11.4 m × 5.3 m: 271 parts with Layher Blitz, 481 parts with Layher Allround and 567 parts with PERI UP.

What parts make up a scaffold?
A scaffold is made of load-bearing parts (standards or frames on base jacks), horizontal parts (ledgers and transoms), working platforms (decks), edge protection (guardrails and toeboards), bracing (diagonal braces) and anchoring (wall ties). On the 11.4 m × 5.3 m example house that gives 271 parts with Layher Blitz, 481 parts with Layher Allround and 567 parts with PERI UP.
The parts and what they do
The definitions are the same as in the scaffolding glossary.
- Base jack: An adjustable screw jack under each standard that levels the scaffold on the ground or on a base plate.
- Standard: A vertical tube that carries the scaffold's load down to the ground; in a frame scaffold the standards are part of the frames.
- Frame: A prefabricated vertical element of two standards with welded crossbars, the main part of a frame scaffold.
- Ledger: A horizontal member along the wall that joins two standards and carries decks or guardrails.
- Deck: The working platform laid on a lift between the ledgers or frames, in steel, aluminium or timber.
- Guardrail: Rails at about 1 m and 0.5 m above the deck on the open side, so nobody falls off the platform.
- Toe board: A board along the edge of the deck that stops tools and material from sliding off.
- Brace: A diagonal member that stiffens the scaffold along the wall so it does not sway.
- Wall tie: An anchor that ties the scaffold to the building so it cannot tip over; the number follows the system's tie rule.
- Stair tower: A scaffold bay with stair flights between the lifts that gives safe access to every working level.
How many scaffold parts does the example house need?
The 11.4 m × 5.3 m example house with a gable roof (eaves 4.5 m, ridge 6 m), calculated by ScaFix with three systems. Parts per part type:
| Part type | Layher Blitz | Layher Allround | PERI UP |
|---|---|---|---|
| Frames and standards | 60 | 96 | 120 |
| Decks | 25 | 25 | 33 |
| Guardrails | 36 | 72 | 96 |
| Toeboards | 24 | 24 | 32 |
| Diagonals | 16 | 8 | 8 |
| Ends | 20 | 16 | 8 |
| Wall ties and fittings | 56 | 56 | 74 |
| Base jacks and legs | 34 | 64 | 40 |
| Ledgers and beams | – | 120 | 156 |
| Parts in all | 271 | 481 | 567 |
Questions and answers
What are the parts of a scaffold called?
The main scaffold parts are standards or frames, ledgers and transoms, decks, guardrails, toeboards, diagonal braces, base jacks and wall ties. Modular scaffolds use standards with rosettes and loose ledgers; frame scaffolds use prefabricated frames.
How many scaffold parts does a house need?
It depends on the system, the walls and the height. For the 11.4 m × 5.3 m example house, ScaFix calculates 271 parts with Layher Blitz, 481 parts with Layher Allround and 567 parts with PERI UP. The systems are built differently, which is why the numbers differ.
How do I get the parts list for my own scaffold?
Enter your walls with length and height in ScaFix and pick the system. The app calculates every part per wall and shows the scaffold in 3D.
