utility structures. Power stations, water treatment works, communications masts and similar structures provide the basic utilities required for our modern lifestyle. Often subjecting the struc- ture to very demanding conditions these utilities have to provide total reliability every day, while minimising environmental risk. To balance output and increasingly important environ- mental considerations these struc- tures require extremely high stand- ards of design and construction. HALFEN provides the high technology hidden components that allow these structures to be successfully designed and...

Connections within power and water treatment structures are critical to construction and long-term performance. • Floor connections for switchgear Application Requirements *- High dynamic load *- Exact positioning Connection of services in pumping Application Requirements Exact vertical positioning Minimal maintenance Weir plate connections in water treatment plant Application Requirements radiused lining Fast installation Exceptionally high corrosion resistance
