SYSTEM 01.04 · MULTI-SPAN CONFIGURATION
MS-1200: 12.0 m multi-span film house, 40×90×2.0 arches at 1.0–1.2 m.
Reference configuration for wide bays and fewer gutter lines. The widest standard multi-span before a truss. Span 12.0 m, bay 4.0 m, eaves 4.0–6.0 m, 40×90×2.0 arches on 1.0–1.2 m centres, G 300 gutter line.
The 12.0 m span is the number that decides everything else in this house. At this width the arch carries a predictable bending moment, the gutter carries the bay load, and the post under the gutter carries both. Change the span by a metre and all three change.
| Member | Section | Spacing | Note |
|---|---|---|---|
| Arch | 40×90×2.0 | 1.0–1.2 m | bent to roof radius |
| Gutter | G 300 | per bay line | brackets at each arch |
| Purlin | C 80×40×15×2.0 | 1.0–1.2 m | punched to pattern |
| Gutter post | Ø60.3×2.0 | each arch | base plate or anchor |
| End frame | Ø48.3×2.0 + bracing | each end | door frame integrated |
| Fittings | clamps / brackets | per member | BOM with the frame |

What changes when you move up a size
From 6.2 m to 8 m the arch section usually stays the same and the gutter grows. From 8 m to 9.6 m the arch has to step up to 40×80, and from 9.6 m to 12 m either the arch goes to 40×90 or the house gains a truss. That step is the single biggest price jump in the range.
