The 30' Polytunnel is the widest standard single span tunnel. It has a circumferential length over the hoop of 13.4m which is ideal for using the widest polythene sheet available (14m) fixed to a base rail. It is necessary to have a base rail with this width of tunnel as the cover is not wide enough to be buried into the ground. The straight sides are slightly higher than out other structures and at 4'2" they are probably the highest on the market. The steel used is the 60.3mm Z35 pre galvanised tube. There are additional inner diagonals as introduced on the 27' model and also an additional strut at each end which supports the centre of each goal post end frames.The timbers are tanalised 3" x 3" with a H-frame above the doorway of 3" x 2". The foundation tubes are 1½" nominal bore hot dipped galvanised tube which allows usual tensioning of the cover after sheeting.
The standard sizes we supply are with the hoops at 6ft spacing's.
