ALTRAD MAG 42 scaffold: bay lengths, depths and parts list

ScaFix plans ALTRAD MAG 42 scaffolding with the system's own bay lengths (3 m) and depth (0.74 m), draws the scaffold in 3D and works out the parts list. Below is our example house with ALTRAD MAG 42.

How many parts does ALTRAD MAG 42 need for a house?

ScaFix plans ALTRAD MAG 42 with the bay lengths 3 m and the scaffold depth 0.74 m. On ScaFix’s 11.4 m × 5.3 m example house, scaffolded all round, ALTRAD MAG 42 needs 216 parts; Jamax needs 268 on the same house.

Good to know

Ties from ALTRAD's MAG 42 sheet (one tie per 24 m², unsheeted); bracing follows ScaFix's general rule because the sheet prints none.

ALTRAD MAG 42 compared with similar systems on the same house

The same example house, computed by the same engine with each system's bay length and default depth. The difference in piece count comes from the bay length, the depth and how the system is built.

How to compare the setup

  • These are fixed ScaFix examples, not customer jobs. Use the wall dimensions and roof shape stated with each example.
  • Compare the same system variant, bay lengths, scaffold depth, deck heights and access. Matching house dimensions alone do not give matching parts lists.
  • The displayed quantities are calculated by ScaFix's engine. Check the setup against the manufacturer's assembly instructions and the actual job; a parts list is not a structural calculation.

Limits

  • The number of wall ties follows the system's tie rule. Their positions must be checked against the manufacturer's assembly instructions.
  • Round corners, silos and hanging scaffolds are in Pro. A round scaffold is not a standard configuration and needs a calculation or the supplier's documentation. A hanging scaffold (Layher Allround and HAKI Universal) always needs a structural calculation from the supplier or an engineer.
