An all British shielding structure using a unique modular system from a series of purpose made components produced from the highest quality materials. The self supporting aluminium structure is designed, manufactured and installed under our strict quality control. Each RF cage is produced to suit local site conditions. The rigid construction is easily adapted to overcome late changes in sizes and specification and allows the easy introduction of additional filters. The finished product exceeds the attenuation levels required by the major equipment manufacturers. Our designs are regularly revised and updated as new scanners are introduced. The standard thickness of the walls and ceilings is approximately 50mm, excluding any internal finishes. Floor thickness, excluding the final covering but including the 4mm base insulation membrane, is approximately 27mm. Our cage is produced from a series of single and multiple extruded aluminium tube sections locked together with special brackets to form a rigid frame of walls, ceiling and floor. The floor frame is infilled with high density boards to give a flush finish. Additional supporting pads for the magnet can be introduced if necessary. The internal surfaces of the frame are lined with aluminium sheet, locked into the threaded groove in the extrusion with a face fixed moulded aluminium cover strip. This unique system gives a double overlap of the material at each panel joint for the maximum level of performance.
