The frictionless movement of modern rolling stock produced by Siemens and Bombardier depends heavily on the maintenance depots serving each of the six lines. SFS UK was invited to quote for suitable fasteners for three of the six maintenance bays.
The building of the maintenance hall envelope for line 1 (North-South, blue) and line 2 (East-West, red) was entrusted to the company Arabian Profiles in Sharjah. Following intensive discussions and evaluation with the SFS team of experts, a standing seam Aluminium profile was chosen, to be retained using SFS SX3 A4 austenitic, self-drilling fasteners. The SXC sandwich panel fasteners safely secured the Zamil Steel wall panels.
While Kalzip, based in Germany was awarded with the standing seam for line 3 (East-West, orange) depot, Dark Globe, from Portugal,was responsible for the installation.The main contractor, Salini, a joint venture bidder from Italy, elected to source the fasteners directly from SFS. The architects had indicated a requirement for 1,550,000 painted AP14 rivets used on the overlap of the roof deck. SFS also provided 380,000 TDA fasteners for fixing the halters to the deck. A further 100,000 TDB-S self-tapping fasteners were used to join the deck to the main steel.
