Lindapter CE Marked Hollo-Bolts Specified For Central Square, Leeds The multi-million U-shaped building is structured around a large fully glazed winter garden with a modern exposed steel design. The atrium framework is secured with Lindapter’s CE Marked Hollo-Bolts which connect structural hollow section back to circular hollow section to form five bowstring trusses. The 27m-tall trusses support a large balcony on level 8 and allow all floors to benefit from natural daylight. Lindapter’s countersunk M16 HolloBolt was chosen to secure the beams and splice connections because of their high clamping force, independent product approvals and discrete architectural finish. The simple installation required access from one side only and did not require drilling or welding, helping the contractors to complete the project on time. In addition to the atrium structure, Lindapter composite decking fixings were used for suspending building services throughout the entire 12 storey office building, including the first two floors which are dedicated to retail, leisure and health and fitness. 10 As a British pioneer with over 80 years’ experience in designing and manufacturing steel-to-steel connections, Lindapter has an extensive range of independent product approvals. Although Lindapter invented the first blind fastener in 1948, the range has developed significantly and today the Hollo-Bolt is available in various architectural head types, lengths and finishes.
