BITEC, the Bangkok International Trade & Exhibition Centre, is a large exhibition venue located east of Bangkok in the Bang Na district.

Dextra was involved in the Phase 2 expansion of the exhibition center, which took place between 2014 and 2016. The expansion project added three exhibition halls, increasing the exhibition space by more than 32,000 sqm under a ceiling height of 25 meters.

Dextra trabajó junto con el contratista italo-tailandés para diseñar y suministrar tension rod systems that support the roof structure above the new BITEC exhibition halls.

In total, Dextra delivered 298 assemblies in various diameters, each composed of multiple rods connected with couplers and turnbuckles and anchored to the structure with fork ends. In several cases, the total assembly length exceeded 50 meters (with an average of 33 meters).

Delivery took place at the end of 2015, and installation was completed by mid-2016. Bangkokians can still easily admire the barra de tensión roofing structure when stopping at BTS Bearing station or driving along the Bang Na-Trat highway.

Para estructuras tan grandes, tension rods Ofrecen una serie de ventajas en comparación con otras soluciones de “tensado”: menor alargamiento bajo cargas, menores fuerzas de postensado requeridas, mejor resistencia a la corrosión, menor relajación a largo plazo y menores costos de mantenimiento y vigilancia.

Además, son fáciles de instalar gracias a sus extremos en forma de horquilla y ofrecen una estructura de tejado muy estética.
