First Tunnels polytunnels are sectional buildings which allows the grower the wildest choice and specification to provide the ideal environment for the crop in production. Their straight sides give excellent working and growing space and are a huge improvement on the old style elliptical tunnels.

We have two bending machines, tube swagers, punching and tube forming machines. We have sawing machines and a full range of metalwork facilities. This allows us to have complete control of our manufacturing processes to ensure high quality at very competitive prices.

All our Polytunnels use large diameter, high tensile steel tube manufactured by Europe’s steel manufacturers. All steel used is galvanised inside and out for maximum corrosion protection and to the Z35 specification. This means that it has a much higher bending resistance than standard mild steel tube and is therefore stronger in use.

The swage joint system is used on all our Polytunnel designs. A swage is where the tube end is reduced in diameter. This allows the tubes to be sleeved together giving a low cost and a extremely strong joint, which means the structures are fast to build and have a very strong anchorage in the ground. They all have excellent side clearance and shoulder room. Close hoops spacings also increases the strength and reduces unsightly polythene or plastic ‘sag’ and consequently loss of headroom.

Whilst our standard structures are sturdy and strong, certain sites may demand greater performance. Crop bars are usually added to increase snow load performance and wind resistance not to mention their use for suspending hanging baskets.

Should you require a specialist design or variation on our range of Polytunnels, please do not hesitate to call, we are only happy to assist you.
