Typical Applications

With rebar couplers, columns can be casted at full height, resulting in faster construction cycle.

Without couplers, lap length is required for continuation bar connections. The formwork needs to be tailor made with holes for rebars, often resulting in concrete leakage.

Without couplers, the casting of core wall can only be done floor by floor, along with slab. Couplers will simplify the construction!

Couplers not only eliminate unnecessary rebar cost and rebar wastage up to 10%, but they also reduce the congestion of rebar at lapping area.

Couplers help maintain load path and structural integrity, and reduce cost of overlap length of rebar.

Bending and unbending the bars require more tools and may cause the risk of bar break. Couplers make the installation of continuation bars easier.

To connect pre-fabricated cages, caging couplers are a more flexible and fast method than traditional bar welding.

The use of couplers results in a faster construction cycle and rebar connection.

When space is limited on project site to install a tower crane for the construction of high-rise buildings, an opening in the floor slabs is required. By leaving bridging couplers inside the slabs, the reconnection is easy and time-saving.

The lack of protruding bars on main pier allows for the use of climbing or slipping formworks for faster construction cycles.

Per Bar End

One operator one machine


Light and productive rebar coupler solution.

This splicing system based on cold-rolled parallel threads requires only a single machine and a single operator for its rebar preparation. Like all Dextra splice systems, Rolltec® offers the full range of splice solutions (standard, position, transition, caging) and covers a large range of both metric and imperial measurements.

2 steps process

Thread Rolling

Anchoring alternative to hook bars and long development length.

Headed Bars are a simple and effective alternative to hooks and long development lengths.
A compact disc is mounted onto the reinforcement bar end. The assembly of the rebar and the anchor provides an anchorage superior to long straight or bent reinforcement bars while being simpler and faster to install.

Headed Bars contribute to reducing rebar congestion in the heavily reinforced area, which ultimately eases the compaction process and result in better concrete quality in key areas of the structure.

GFRP rebar for permanent applications.

Corrosion-free alternative to steel rebar, GFRP rebar allow contractors to substitute steel rebar with composite non-corrosive and non-metallic reinforcement. ASTEC Glass Rebar can be used for both new construction or as a strengthening material. ASTEC GFRP rebar solutions offer very high tensile performances for a lightweight: up to 8 times the performance/weight ratio of steel.

Since 1996, Dextra has established new standards becoming the worldwide reference in FRP rebar manufacturing, made by pultrusion. Precursor of this technology, we have successfully supplied thousands of projects all around the world.

For more information, please refer to our technical documentation. Dextra design team is also available to support you in the design and optimization of your GFRP rebar use.


Composite GFRP Rebar.

Corrosion-free alternative to steel rebar Dextra has been a leader in the composite industry for the past 25 years, manufacturing high-quality FRP solutions supplied on large infrastructure projects.

The company excels in offering comprehensive solutions to its customers, with expertise in designing concrete structures reinforced with GFRP rebars.

All Durabar™ GFRP rebars are produced in Dextra ISO-9001 and ISO-14001 certified factories in China and India, following the company’s stringent quality assurance policy.
