Bangkok BTS

Bangkok BTS

The Bangkok mass Transit System (BTS) is a large urban skytrain system located across Bangkok, the capital city of Thailand. The system was inaugurated in 1999.

As of 2017, the system consists of 24 elevated stations and 37 km of elevated rail organized in two main lines crossing each other in Siam central station.

The BTS system is undergoing an extension of its two main lines with line segments and stations expected to enter in operations in 2019 and 2020.


For various packages over the years, Dextra has supplied Sonitec tubes, which are used to test the concrete pile foundations below stations and rail.

In total, Dextra supplied approximately 40,000 linear meters of Sonitec tubes, a distance actually equivalent ot the BTS system length itself.


For pylon vertical bar connections, Dextra offered its Bartec connection. Bartec allows to conveniently splice prefabricated rebar cages by the use of a simple rebar coupler, allowing savings in steel compared to overlap and accelerating site operations.

In Thailand the threading operation is supported from Dextra’s factory, conveniently located in the North East of Bankgok. Contractors receive the rebar already prepared and mounted with their rebar coupler.
