The deflection head detail is required because all buildings are subject to pressures which can mean that the roof will move either up or down IE if there has been great snowfall meaning that the roof will be subject to extreme weight loading or when the wind is extremely high and large roller shutter doors are open then the wind can produce very high pressure within the building which has the effect of lifting the roof, up therefore the deflection needs to be both up and down and this is normally calculated by structural engineers as to how much deflection is required.

At PJS Solutions we can provide solutions for deflection heads up to+/- 200mm of movement which is quite exceptional.

Due to the multitude of scenarios at which various width partitions at various heights can be attached to the roof either to the portal rafter frame, running across the roof purlins or running parallel to the roof purlins, we have hundreds of solutions for deflection head details which will accommodate the partitions.

There are too many deflection head details to list on this website so please either call or email with your inquiry and we can provide you with the solution that best fits your requirements.
