Suvarnabhumi Airport is the main international airport of Thailand, operating both domestic and international flights and acting one of the main gateway to South East Asia for travelers in the region. The airport is located at the east of Bangkok, less than 15 minutes from Dextra main manufacturing facility.

Dextra est impliqué dans la construction de l'aéroport depuis le début en 2001 et a encore contribué aux derniers projets d'agrandissement de l'aéroport.

La deuxième phase d'agrandissement de l'aéroport de Suvarnabhumi vise à augmenter la capacité annuelle de traitement des passagers de l'aéroport à 60 millions de passagers et à fournir 28 portes d'embarquement supplémentaires pour les vols internationaux, amenant le service aux normes internationales et améliorant le confort des passagers et des compagnies aériennes sur une superficie totale de 960 000 mètres carrés.

Plus de 600 000 coupleurs de barres d'armature Bartec ont été largement utilisés dans toutes les parties des aéroports, y compris les poutres, les colonnes, les parois moulées et les cages à pieux. Cette solution d'épissage de barres d'armature populaire permet une connexion sûre et fiable des barres d'armature, pour les applications verticales ou horizontales.

The solutions were delivered with rebar preparation equipment, along with our trained experts, to ensure that production requirements were met in a timely manner.

Moreover, RepairGrip and Unitec couplers were also used for the connection of two rebars with no thread or rebars that have splicing issue.

Heathrow Airport, located approximately 25 km west of central London, is the busiest international airport in the United Kingdom.

Dextra was involved in the construction of Terminal 5 and its associated structures.

For Heathrow Airport, Dextra provided its most advanced rebar Solution de raboutage: Griptec, which is distributed in the United Kingdom by local expert fabricators.

Due to its high performance, inherent reliability, systematic proof loading of every connection in factory conditions, and comprehensive certification, Griptec is specified by major consultants worldwide. In the United Kingdom, Griptec holds all three CARES splicing product certificates: TA1-A, TA1-B, and TA1-C.

For our distributors servicing rebar preparation, the Griptec solution is both convenient and productive. It is supported by a smart machine operated by a single operator, offers highly efficient cycle times (approximately 45 seconds per rebar prepared), and includes a test that systematically proof loads each and every bar/sleeve connection.

For contractors, Griptec provides a simple, effective, and reliable way to connect rebar in columns, parois moulées, and slabs. One application at Heathrow was for the roof of the new underground station. Griptec connections were also used to create temporary openings that allowed workers and equipment to move freely through the rebar structure and could easily be “closed” using single lengths of rebar with Griptec connections at both ends.

Thanks to its parallel-thread technology, Griptec does not require any specific torque wrenching and can be verified through simple visual inspection, offering a significant advantage in simplifying the project schedule and maximizing operational productivity.

Mumbai Chhatrapati Shivaji International Airport is the primary airport serving international airports to Mumbai. It is the second airport in India in term of passenger traffic.

Dextra a participé à la construction du Terminal 2 et des structures associées, qui a eu lieu entre 2009 et 2013.

For Mumbai Airport, Dextra delivered its popular Bartec rebar coupler solution, which is the primary rebar coupler used on large projects in India.

Dextra operates its own threading yard in Mumbai and took responsibility for the rebar preparation for this project.

Sur le chantier, Bartec was used extensively for vertical connections (bar-to-bar vertical column connections) as well as horizontal applications (column-to-beam), typically for reinforcement of ⌀32mm. Bartec offers an exceptional level of performance, ensuring “bar break” performance on the rebar used at Mumbai Airport.

For the contractor (Larsen & Toubro on this project), Bartec offre un moyen simple et rentable de connecter des barres d'armature.

Thanks to its parallel thread technology and rebar prepared with various thread lengths, it requires the same coupler for both standard applications (when one bar can be rotated inside the coupler) and positional applications (when no bar can be rotated). This is a convenient feature that simplifies stock management and prevents product mismatches on site.

King Abdulaziz International Airport (KAIA) is an international airport located in Jeddah, Saudi Arabia.

The airport, named after the founder of Saudi Arabia, King Abdulaziz Al Saud, is the country’s third-largest and busiest airport.

KAIA has four operational passenger terminals: the North Terminal, South Terminal, Hajj Terminal, and Terminal 1. The Hajj Terminal was specifically created for Muslim pilgrims traveling to Mecca each year for the Hajj.

Dextra supplied more than 300,000 Bartec couplers, which were installed in various structures, including bridges, tunnels, railway stations, terminals, the ATC tower, and car parking facilities.

Suvarnabhumi Airport is the main international airport of Thailand, serving both domestic and international flights and acting as one of the primary gateways to Southeast Asia for travelers in the region. The airport is located east of Bangkok, less than 15 minutes from Dextra’s main manufacturing facility.

Dextra has been involved since the beginning of the Suvarnabhumi construction in 2001 and continues to play a role in the airport’s latest expansion projects.

Over the years, Dextra has provided a wide range of technical solutions to support various contractors on different parts of the project.

For foundation piles, parois moulées, columns, beams, and other concrete structures, Bartec rebar couplers have been extensively used throughout the airport. This popular coupler solution ensures safe rebar connections, both vertical and horizontal. In Thailand, Dextra also handles rebar preparation services, which are carried out at our own threading yard in Bangkok.

The terminal roofs and concourses were designed to use Dextra Tension Rod Systems as cross-trusses. These high-performance large bar systems are easy to install and adjust in length, thanks to their fork ends and in-line connectors, while also contributing to the overall aesthetics of the terminal structure.

For the plane remote parking area, where aircraft fine-tune communications with the control tower, Dextra supplied large-diameter PRF Goujon bars to connect the tarmac concrete slabs. Dextra’s PRF bars offer similar tensile performance to steel bars but help reduce the interference typically associated with metallic structures.

Kuwait International Airport is the country’s main airport, located to the south of Kuwait City. The hub currently handles more than 9 million passengers annually and is home to the renowned Kuwait Airways, Jazeera Airways, and Wataniya Airways.

The Mexico City New International Airport is a major infrastructure project designed by Sir Norman Foster and launched in 2014. It aims to provide Mexico’s capital with a state-of-the-art airport hub by 2020. The project is located to the east of Mexico City and is set to accommodate an annual passenger capacity of 68 million, surpassing the previous Benito Juarez Airport, which currently handles 41.7 million passengers annually and is the busiest airport in Latin America. The project features an X-shaped passenger terminal, three runways, and a control tower.

For this, the largest infrastructure project in Latin America, Dextra has been involved in supplying its Coupleurs de barres d'armature Bartec for the foundations of the terminal building (contractor ICA), the transport building (contractor Sacyr), and the control tower (contractor Aldesa).

Bartec couplers, often preferred in seismic areas like Mexico, replace the traditional lapping of large ASTM #12 rebar (equivalent to 38mm) on this project. For such large diameters, it is both faster and more cost-effective to connect bars with couplers rather than using traditional overlapping methods.

Dextra has provided Mexico Airport with up to 10 sets of Bartec equipment (a total of 30 machines, with each set delivered in a container) for all rebar preparation operations. This impressive setup has been supported by our local After Sales team, who have trained the machine operators and maintained the equipment to ensure optimal productivity.
