We suggest you continue reading onto the following pages, which explain how our designs work for you and the differences between our Euro, Standard and Multispan ranges. If you have access to the internet, our website www.polyhouses.com includes case studies which cover most of our product range. The perspective drawings on each page give an idea of scale and illustrate the bracing layout and optional timber end frame arrangement. We separate these from the main polyhouse to enable you to source your own timber if so desired.</p> <p>Our designsAll Polyhouses use large diameter, high tensile steel tube manufactured by our UK steel suppliers to Z35 specification. This means that it has a much higher bendingInside Galvanised steel Outside Zinc Z35 Alloy Steel Zinc</p> <p>resistance than standard mild steel tube and is therefore stronger in use. The large diameters give additional strength for resistance to wind and snow loads. Most foundation tubes have a 2mm plus wall thickness. The foundation tubes are a key part of the Polyhouse and it is vital to ensure maximum strength in this area. All tube is galvanised inside and out for maximum corrosion prevention. In normal conditions we have seen our Polyhouses exhibit little serious corrosion, even after 20 years use.</p> <p>PlanningIn nearly all instances planning perFordingbridge pioneered the use of swaged joint systems in polyhouse design and use this extensively throughout our Polyhouses.

This allows tubes to sleeve together giving a low cost, extremely strong joint which is fast to assemble. The foundation tubes to hoops, the hoops themselves and the ridge and crossbraces use this swage system. All Polyhouses have corner windbrace diagonals and most have an additional gable end roof diagonal support.</p> <p>DimensionsAll Polyhouses dimensions are quoted centre of foundation tubes down the length of the building. Single span foundations tube measurements are given as the outside dimension across the hoop span at ground level. On multispans the inner span dimensions given are centre of gutter to centre of gutter.</p> <p>CladdingThe hoop circumference of each Polyhouse is shown to calculate the width of cladding required.

Actual base sizes are covered in our instructions, but as a guide you will need 1 cubic metre for every 10 foundation tubes. A 7m x 18m would therefore need around 2 cubic metres. For larger projectsFoundation tube in concrete</p> <p>of the polythene or netting at the sides of the tunnel, unless a ground level rail is used. If providing your own cladding, you must add at least 0.75m (2ft 6ins) each side to trench into the ground, or at least 0.3m (1ft) if cladding to a side rail. Please note that anti-hot spot tape is included in the price of polythene when ordered with a new Polyhouse framework.</p> <p>we would normally use ready-mix. A 20 Newton metre/GEN3 mix should be ordered. A ready mix load is normally 6 cubic metres so you will need to work fast! For larger sites we would suggest you hire a mechanical auger with a 500mm bit.
