Dextra มีส่วนร่วมในการก่อสร้างอาคารผู้โดยสาร 2 และโครงสร้างที่เกี่ยวข้อง ซึ่งเกิดขึ้นระหว่างปี 2552 ถึง 2556

For Mumbai Airport, Dextra delivered its popular บาร์เทค 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.

ในสถานที่ก่อสร้าง บาร์เทค 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. บาร์เทค 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), บาร์เทค เสนอวิธีที่ง่ายและคุ้มค่าในการเชื่อมต่อเหล็กเส้น

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.
