STEEL:


All steel tubes are galvanised both inside and outside for longer life (to Z35 standard) with a 1.5mm wall thickness. 


HOOPS:


Two-piece, 60mm steel hoops spaced at 6ft apart (closer spacings can be catered for). 1.83m (6’) straight sides allow for a full working height right up to the inside edge of the structure. 


GROUND TUBES:


Thick walled (3.25mm), heavy gauge, galvanised foundation tubes give longer life and provide a secure structure. 


CROSS BRACING BARS (CROP BARS):


Optional 50mm tubular steel bracing bars (crop bars), supported from the ridge tube by two 32mm tubular steel hangers. Cross bracing bars, not only add strength to the structure but are also used for suspending irrigation spray lines, tying up crops such as tomatoes and vines, and for suspending hanging baskets. 


BASE RAILS, SIDE RAILS AND END FRAMES:


Tanalised 100mm x 50mm (4”x 2”) timber base and side rails. Tanalised 75mm x 75mm (3”x 3”) timber end frames. The timber we use has been Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC) certified, demonstrating our commitment to sustainable forest management


Aluminium options are also available. 


POLYTHENE:


Our standard cladding is 720g (180µm) ‘Visqueen’ anti-drip polythene, with either a clear or diffused option. We also offer a 600g (150mu) 50:50 option, which only has half the normal level of diffusion, making it 50% clear and 50% diffused. Our polytunnel design allows the polythene to be re-tensioned after fitting to get a drum-skin tight cover.

ANTI HOT SPOT TAPE:


Padded foam tape which acts as insulation between the metal and the polythene, to prevent the build-up of heat in the steel frame being transferred to the polythene. Extends the life of the polythene sheet by at least one year. 


DOORS:


Single or double sliding aluminium doors incorporating our Ali-trap polythene fixing system. One-piece, aluminium door track and pelmet (combined) for smooth, trouble-free operation. 


VENTILATION:


Optional side netting with internal roll-down polythene screen. Also available, louvres, roof vents and automatic ventilation systems.
