Birmingham New Street Station and Grand Central Building

Sectors: Rail
Applications: Stainless Steel Facade connections


After Martifer designed the stunning façade, Network Rail stipulated that self-drilling screws were not suitable because the fixing must exceed the 40 year life expectancy of the stainless steel façade panels. Therefore, Network Rail's Civil Engineer for Birmingham New Street Gateway Project explored various cladding fixings from the UK, European and USA markets. He even considered using British Aerospace, BAE System, jet fighter's body riveted connection. The Civil Engineer decided that Lindapter’s Hollo-Bolt was the best connection solution for this iconic structure as it met Network Rail’s safety and maintenance requirements and the Council Planners needs.
The Engineer took advantage of Lindapter’s free connection design service and the research and development department to receive an engineered solution. The Lindapter R & D team developed a bespoke M5 countersunk Hollo-Bolt in stainless steel, which exceeded the maintenance and safety requirements, complemented the design of the façade and provided a quick and easy installation process. Lindapter products have been used throughout the £750 million renovation of Birmingham New Street and Grand Central building. As well as securing the façade, Lindapter fixings have been used to connect the building services, station fittings and over 60 premium retailers’ shop fronts.
As a premium British manufacturer with over 80 years experience, Lindapter has a wide range of product approvals. The Hollo-Bolt is the only expansion bolt that is featured in the BCSA and SCI design guide ‘Joints in Steel Construction’. It is also the only structural steel expansion bolt to have full seismic approval from Californian-based ICC-ES for resisting wind loads and seismic loads.
