Fast-action external door

At Greencell's Spalding plant, a Stertil FlexiEdge M2 fast-action door was specified to replace an existing external door that had reached the end of its working life.

The door curtain is fully flexible with a soft bottom edge which not only self-adjusts to seal on an uneven floor but also avoids any possibility of causing injury to users. In addition, the incorporation of an infra-red photocell, fitted 300mm above floor level, supported by a bottom edge wireless detector ensures instant halting of all door movement in the event of sensing an obstruction of any kind. Also, the flexible soft-edge curtain provides maximum resistance to damage caused by a vehicle collision. If the door edges are knocked out by the collision, they are automatically re-inserted in the side guides as the door opens. 

Due to the exposed nature of the Greencell Spalding plant, the Stertil FlexiEdge door has to cope with adverse weather conditions including unusually high wind loadings. However, the incorporation of top quality materials including galvanised steel for structural strength allied to reinforced polyethylene side guides ensures that the door’s performance and reliability is not compromised.
