SYSTEM 05.02 · HIGH TUNNEL CONFIGURATION
HT-600: 6.0 m high tunnel, 3.0 m at the bow.
Reference high tunnel for market gardens and season extension. Width 6.0 m, bow Ø48.3×2.0, roll-up sides, ground-screw anchors.
HT-600 is the simplest frame we quote, and the one where the details matter most. At 6.0 m wide there is no gutter and no post line: every load goes through the bow and its anchor. That is why we quote anchors as a line item rather than an accessory.
| Member | Section | Spacing | Note |
|---|---|---|---|
| Bow | Ø48.3×2.0 | 1.0–1.5 m | bent to radius |
| Longitudinal brace | Ø33.5×1.8 | mid-height | one per side minimum |
| Roll-up side | Ø33.5 + ratchet | per side | film + channel |
| Anchor | ground screw 600 mm | each leg | or concrete |
| End bow | Ø48.3×2.0 | each end | door frame |
Reference only. Wind exposure decides brace count and anchor length.

The cheapest upgrade
A second longitudinal brace and longer anchors cost a fraction of a new frame and add more storm capacity than a heavier bow. Ask for both in the first quotation.
