Made from galvanised steel, crops bars are fixed across the intermediate hoop at head height.(excluding the two ends)
Another beneficial effect of Crop Bars is they also help strengthen the Polytunnel, providing extra protection against heavy winds on particularly exposed sites.
First Tunnels make crops bars for use exclusively on their range. However, they can make crop bars in any size to suit other makes of Polytunnels.
