Chennai International Airport is the main airport serving the southern city of Chennai in India. Located to the south of the city, it is the fourth busiest airport in India.

Dextra was involved in the construction efforts surrounding the airport’s renovation, which took place between 2008 and 2012.

For Chennai Airport, Dextra delivered its popular บาร์เทค rebar coupler solution, which is the primary rebar coupler used in large projects across India.

The main contractor for this project was Herve Pomerleau International (HPI) – Consolidated Construction Consortium Limited. The contractor chose the Bartec solution to splice การเสริมแรง in all columns and ท่าเทียบเรือ (vertical connections) as well as for beams and foundation mats.

Thanks to its parallel thread technology and rebar prepared with various thread lengths, Bartec offers a very high level of performance. It requires only one coupler for both standard applications (when one bar can be rotated inside the coupler) and การประยุกต์ใช้เชิงตำแหน่ง (when no bar can be rotated).

Mae Fah Luang Chiang Rai Airport, located in Chiang Rai, Thailand, is a vital transportation hub for the region. Serving as a gateway to popular tourist destinations like Chiang Mai, Chiang Rai, and the Golden Triangle, the airport has recently undergone a significant renovation and expansion project aimed at modernizing its facilities and increasing its capacity. As part of this project, Dextra supplied over 180 tons of เหล็กเดือย หรือ เหล็กโดเวล เหล็กเส้นสำหรับใช้ในงานก่อสร้าง จุดต่อ in the airport’s runway pavement.

The construction of a runway pavement requires careful planning and preparation. One essential component of the runway pavement is the construction joint, which connects individual concrete slabs. These จุดต่อ are necessary to ensure that the pavement can withstand the heavy loads of aircraft and endure extreme weather conditions. Without proper construction จุดต่อ, the pavement may experience cracking, spalling, and other types of damage.

เหล็กเดือย หรือ เหล็กโดเวล bars are a critical component of construction จุดต่อ, as they facilitate load transfer between individual concrete slabs. Typically made of steel, เหล็กเดือย หรือ เหล็กโดเวล bars are placed perpendicular to the construction joint, allowing for movement between the concrete slabs while providing support and enabling efficient load transfer.

For the Mae Fah Luang Chiang Rai Airport project, Dextra supplied over 35,000 เหล็กเดือย หรือ เหล็กโดเวล bars, totaling more than 180 tons of steel. The เหล็กเดือย หรือ เหล็กโดเวล bars were manufactured at Dextra’s facility in Thailand and delivered to the construction site in stages to meet the project’s timeline.

The successful completion of this project has not only increased the airport’s capacity but also improved its safety and reliability, providing a more efficient transportation hub for the region.
