The world famous Roland Garros Stadium is a complex of tennis courts located in Paris, that hosts the French Open, a Grand Slam championship tennis tournament. The facility was constructed in 1928 and was in need of modernization to keeps its Grand Slam status. The French Tennis Federation proposed a significant expansion which included the reconstruction of the main Philippe-Chatrier Court and stadium.
The stadium expansion required a huge amount of new steelwork, much of which was specified as hollow structural section (HSS) to provide an ideal balance between strength, functionality and aesthetic appearance. The HSS would be used in many areas of the project including the stairways and concourses, and it was here that the steel contractor needed a solution for connecting 3km of stainless steel handrails to the HSS.
The engineer designed an “L” shaped steel section which would be fixed to the HSS to provide a suitable place for the handrail supports to be connected. Hollo-Bolt, the original expansion bolt for Structural Steel that requires access to only one side of the HSS, was specified for the connection of the steel section to the HSS. Hollo-Bolt offers fast installation, high strength capacity, and a wide range of independent technical accreditations, including CE mark, TÜV and ICC-ES Seismic approvals.
Holes in the SHS and “L” shaped steel sections were pre-drilled off-site by the steel fabricator, to make installation in the field a simple process. The contractor offered up the steel sections to the HSS before inserting hexagonal head, size 1/2" Hollo-Bolts with a JS500 zinc plated finish. Installation was quick and easy as each bolt is simply inserted into the pre-drilled holes and tightened with a torque wrench to the recommended tightening torque to provide the necessary clamping force.
The specification of Hollo-Bolts provided a quick and easy solution for connecting the “L” shaped steel sections to the HSS. The contractor was able to secure the handrail supports to the steel section and then complete the installation of the stainless steel handrails.
