> Framework
The EFASS framework has been specifically designed to maximise strength, minimise weight and still be robust enough to withstand multiple erection and strikes in hostile environments. In order to achieve this, only the highest grade materials and components have been selected with quality being paramount.
The main frame members are manufactured from light weight structural aluminium extrusions. All joints, inserts and footplates are manufactured from high grade steel engineered to gain the most strength with least weight. The aluminium extrusion has been designed with utility slots to accommodate the assembly of components and accessories, both internally and externally, along their full lengths, eliminating the need to weld to the aluminium, which would greatly reduce its structural properties. All major forces are transferred to the steel joints and any stress and wear points between the softer aluminium are taken out by using compression stops. To prevent electrolytic reaction of dissimilar metals and protect from corrosion, the aluminium is anodised and the steel is hot dipped galvanised after fabrication.
> Quality
The quality aspect of the product is brought into the front with attention to detail. This can be highlighted in typical roof and footplate joints, where shear load is taken from steel bolts through the softer aluminium section by providing steel compression stops on the connecting joints. A further example can be seen on footplate where hinge location includes oilite bushes and stainless steel pins.
> Weather Protection Span Joints
Weather Protection is provided by inserting an engineered rubber profile into the outside utility slot over the full length of the span profile. Rubber, although expensive, has proven to be the most effective solution, especially in hot conditions as the other cheaper plastic alternatives deteriorate very quickly.
