A 3 × 4 m frame for a greenhouse you can panel separately
GARDENER DuoArch greenhouse frame The GARDENER DuoArch is a 3 × 4 m greenhouse frame supplied without polycarbonate panels. Its paired-arch design uses a galvanised steel frame, with arches spaced 100 cm apart. The frame is 400 cm long and 213 cm high, and has a stated growing area of 12 m². Galvanising helps protect the steel against corrosion. Choose suitable panels separately, checking that they fit the frame and suit the loads they are expected to bear.
