A 4 × 20 m frame for your greenhouse covering
Choose the covering separately The AGROMAX 4 × 20 m greenhouse frame is supplied without a covering. Polycarbonate is not included, so check that your chosen panels and fixings suit the frame before buying.
Frame details
- A long growing area: The frame measures 4 × 20 m, with a stated height of 2.96 m and an area of 80 m². Compare these measurements with your available space and planned layout.
- Galvanised steel construction: The frame is made from galvanised steel, with galvanising listed as its rust protection. The stated profile sizes are 40 × 20 mm and 20 × 20 mm.
- 200 cm arch spacing: The arches are spaced 200 cm apart, a measurement to consider when selecting a covering for the frame.
- Polycarbonate not included: This is the frame only; polycarbonate is excluded. Check panel dimensions and fixing compatibility before choosing a covering, as these are not supplied with the frame.
- Extension options: The AGROMAX frame can be extended with compatible 2 m sections. These are fitted in the middle of the greenhouse rather than at the end walls; check model compatibility before selecting an extension.
