We are thrilled to announce that our new generation of PC (Pressed Connection) Headed Bars has received certification from both AFCAB in France and CARES in the UK!

AFCAB has certified our model 9D (double chamfer) for general applications. Meanwhile, the CARES TA1-B&C certificate no. 5071 has certified both our models 9D and 9A (single chamfer). These CARES certifications cover a wide range of applications, including general and nuclear construction, showcasing the exceptional performance of Dextra’s product solutions.

Dextra PC Headed Bars, ranging from 10mm to 20mm, feature a circular plate forged to the end of the reinforcing bar. The headed bars meet Eurocode requirements with a load-bearing area at least 9 times the cross-section of the reinforcement bar.

Note

The previous UK Cares certification is now renamed to CARES.
CARES certification does not cover seismic performance. TA1-B is designated for general applications, while TA1-C is for nuclear applications.
The headed bars meet Eurocode requirements concerning load-bearing area.

Cross Island Line (CRL) MRT, Singapore

dextra has played a pivotal role in the construction of Singapore’s Cross Island Line (CRL) MRT project, supplying Glass Fiber Reinforced Polymer (GFRP) soft-eyes, bartec couplers and Barras con cabeza for several crucial packages. dextra continues to support the ongoing packages of this extensive project.

The CRL is set to become Singapore’s eighth MRT line and its longest fully underground line, stretching over 50 kilometers. The project is being executed in three phases, with the first phase anticipated to be operational by 2030.

To minimize the environmental impact on the forested areas of the nature reserve, engineering solutions were meticulously chosen to further mitigate environmental disruption. These solutions include digging deeper into the ground and employing a large diameter boring machine, capable of accommodating two train tracks within a single tunnel. This approach not only reduces the surface footprint but also enhances the efficiency of the tunneling process.

Tunnel Boring Machines (TBMs) are a staple in Singapore’s subterranean infrastructure projects, adept at operating under a variety of ground conditions. The use of GFRP soft-eyes supplied by dextra is integral to these operations. Soft-eyes are essential components in TBM tunneling, acting as temporary openings that allow the TBM to break through concrete walls without compromising structural integrity. The GFRP material is preferred for its high strength-to-weight ratio, corrosion resistance, and ease of installation, ensuring safe and efficient tunneling operations.

dextra‘s expertise and reliable supply of GFRP soft-eyes, bartec couplers and headed bars have significantly contributed to the progress of the CRL project, aligning with Singapore’s commitment to sustainable and innovative infrastructure development. As the CRL project advances, dextra remains a key partner, supporting the construction of this monumental MRT line that will eventually enhance the daily commute for millions of Singaporeans.
