HAKI Universal or Jamax?
Short answer: neither is better in general; it depends on what you own or can rent, and on the facade. In ScaFix, HAKI Universal has bays of 3.05 m and 2.5 m and depths of 1.66 m, 1.25 m, 1.01 m, 0.77 m and 0.7 m; Jamax has bays of 3 m and 2 m and depths of 0.68 m. On the 11.4 m × 5.3 m example house, HAKI Universal needs 450 parts and Jamax 268; on a straight wall of four bays, 6 m high, HAKI Universal needs 168 (12.2 m) and Jamax 113 (12 m).
The two systems in ScaFix
From the app’s system catalogue. Two differences in the setups: HAKI Universal is a modular system with wedge connections and Jamax a frame scaffold, and ScaFix gives HAKI a stair tower for access and Jamax ladders through the decks, so the stair tower’s parts are in HAKI’s total.
| HAKI Universal · 0.77 m | Jamax · 0.68 m | |
|---|---|---|
| Manufacturer | HAKI | Jamax |
| System type | Modular scaffold with wedge connections | Frame scaffold (facade scaffold) |
| Bay lengths | 3.05 m, 2.5 m | 3 m, 2 m |
| Depths | 1.66 m, 1.25 m, 1.01 m, 0.77 m, 0.7 m | 0.68 m |
| Parts in all | 450 | 268 |

The same straight walls with each system
Five straight walls of 2 to 10 bays, 4 to 12 m high, one per row. Each system uses its own longest bay, so the lengths differ slightly.
| Bays | HAKI Universal · 0.77 m | Jamax · 0.68 m |
|---|---|---|
| 2 | 6.1 × 4 m: 73 | 6 × 4 m: 38 |
| 4 | 12.2 × 6 m: 168 | 12 × 6 m: 113 |
| 6 | 18.3 × 8 m: 329 | 18 × 8 m: 180 |
| 8 | 24.4 × 10 m: 509 | 24 × 10 m: 319 |
| 10 | 30.5 × 12 m: 766 | 30 × 12 m: 426 |
How to choose between them
- Use the system you own or can rent nearby: a mixed yard costs more than a few extra pieces.
- Check the bay lengths against your facades: more bay lengths fit odd lengths more closely.
- Compare the depths: a deeper scaffold gives more room to work but uses different decks and transoms.
- Count the pieces to handle, not only the price per piece: more pieces mean more transport and erection time.
- Follow the manufacturer’s instructions and approval for ties and loads; ScaFix plans, it does not approve.
Questions and answers
Which needs more parts, HAKI Universal or Jamax?
On ScaFix’s 11.4 m × 5.3 m example house, HAKI Universal needs 450 parts and Jamax 268. On a straight 4-bay wall 6 m high, HAKI Universal needs 168 and Jamax 113. The count follows the bay length, the depth and how each system is built.
Can I plan both HAKI Universal and Jamax in ScaFix?
Yes. Both are in the system picker with their own bay lengths and depths, and ScaFix draws the scaffold in 3D and works out the parts list for each.
Is a ScaFix comparison an approval of either system?
No. ScaFix is a planning tool. Erection, ties and loads follow the manufacturer’s instructions and approvals, checked by a competent person.
