KERO systems compared head to head

Every pair of KERO systems in the ScaFix catalogue: which bay lengths and depths they share, which only one of them has, and what the planning engine counts for each on the same example house, parts group by parts group.

How do the KERO systems differ?

ScaFix has 3 KERO systems: KERO RHU 070, KERO RK 073 and KERO RPL 070. On the same example house (11.4 m × 5.3 m), KERO RHU 070 needs 288 parts and KERO RPL 070 288. No bay length is offered by all 3 systems, so their bay grids differ.

Pair by pair: bay lengths and depths

Each pair of KERO systems, from the catalogue the engine plans with. «Only in» lists the bay lengths one system has and the other lacks; the last column is the parts total of each on the example house.

Parts group by group on the same house

Each KERO system planned on ScaFix’s example house (11.4 m × 5.3 m) with the default settings. The rows are the groups of the app’s parts list; «–» means the system has no part in that group. How the example is set up is on the methodology page.

Questions and answers

Can I mix parts from two KERO systems in ScaFix?

No. ScaFix plans each wall with one system’s own parts and never mixes systems in a parts list. Whether two systems of one maker may be combined on site is for KERO’s instructions to say. ScaFix is a planning aid, not a structural approval.

Why do the parts totals of the KERO systems differ?

A wall is filled with each system’s own bay lengths, so a shorter bay means more bays, standards and ledgers; the depth changes the transoms and decks, and frame systems count frames where modular systems count standards and ledgers. The totals say nothing about price or load class.
