PRODUCT FAMILY 05 · GUTTERS
Roll-formed gutters that turn the eaves line into a water supply.
200, 250 and 300 mm roll-formed profiles, with end caps, outlets, brackets and stop ends. Buyers increasingly specify gutters not to drain the roof but to harvest it — in dry markets the water is worth more than the steel.
A greenhouse gutter does two structural jobs as well as one hydraulic job: it ties the arch line together and it carries the load of any crop wire hung beneath it. That is why the bracket detail matters as much as the profile width — a 200 mm gutter on a light bracket deflects where a 250 mm gutter on a proper bracket does not.
| Profile | Developed width | Wall | kg/m | Typical bay |
|---|---|---|---|---|
| G 200 | ≈ 520 mm | 2.0 mm | ≈ 8.2 | 6.2–8 m houses |
| G 250 | ≈ 640 mm | 2.0 / 2.5 | ≈ 10.0 / 12.6 | 8–9.6 m houses |
| G 300 | ≈ 760 mm | 2.0 / 2.5 | ≈ 11.9 / 14.9 | 12 m houses, high rainfall |
Developed width and weight are nominal; profile geometry is set by the roll former and confirmed on the profile sheet.
