    Dextra Steel Manufacturer | Rebar Couplers | Tension Bars | Bartec


    Established in 1983 by French expatriate entrepreneurs, Dextra Group has developed over a long history, during which it encouraged those with an entrepreneurial spirit and constantly strived towards innovation and growth, leading to diversification.

    Our three main activities are manufacturing, trading and freight forwarding, all within the construction and industrial sectors.

    Our steel and composite solutions are engineered and manufactured by Dextra in our three production facilities located in Thailand, China and India.

    We engineer and distribute technical solutions for a vast array of construction application: reinforced concrete, rebar nuclear, marine, precast concrete connection and more.

    We engineer and organize very large oversized shipments from/to Asia, taking care for you of all the Thailand logistics behind the most challenging relocations.

    Our Expertise:

    Rebar Mechanical Splicing
    Well known in the construction industry, Dextra rebar splicing solutions allow to swiftly connect reinforcement bars of various grades and diameters. Our range is divided into 3 applications:

    Cast-In-Place >> Mechanical splicing solutions allowing fast, high-performance and reliable rebar connections thanks to their parallel-thread system. Prior preparation of the rebar is done thanks to a highly productive Dextra equipment or directly by sourcing prepared rebar from one of our distributors.
    Precast >> Solutions which allow the connection of precast elements together without the needs of wet in situ joints.
    Repair >> Solutions which do not require the bars to be prepared, can be operated with light tools and require a minimal bar length.

    Bartec coupler is a full performance (tension / compression / cyclic / fatigue) rebar splicing system designed for the connection of concrete reinforcing bars from Ø12 to 50mm (ASTM #4 to #18). A standard Bartec® connection is made of a parallel-thread rebar coupler and two bars whose end have previously been enlarged before being threaded: thus the cross section of the bar isn’t reduced. The benefit is to simplify your inventory: A single standard coupler for most applications.

    Bridges and Viaducts
    For bridges and viaducts construction, Dextra offers post-tensioning bar (PT Bar) systems that can be used for both permanent or temporary applications. Our range takes advantage of both fully threaded bars and smooth bar and includes all required accessories to perform applications such as the post-tensioning of heavy structure or temporary heavy-lifting operations.

    Ground Anchor
    Retaining walls for excavations are vertical and tensile structures that only allow limited deflection. Typically, pre-stressed active anchors are preferred. High strength tendons anchored to the retaining wall on one end and to the ground on the other end through a bulb of pressure injected grout named ‘bond length’.

    On soil-covered slopes, soil is constantly moving downslope due to gravity, therefore larger displacement have to be considered. Typically passive anchors are preferred. High strength tendons are fullygrouted from the face of the slope into the stable ground.

    Frieight Forwarding in Thailand
    Dextra is well used to the most challenging transportation projects having moved over the last 24 years very large items for power plants, petrochemical, and oil & gas industry.

    Precast Connection
    Each Grout sleeve features a threaded end (used for the connection to reinforcement at the precast factory) and a wide cavity to perform a grout connection at site.

  3. #3
    Sonitec
    This is a sonic pipe solution invented to facilitate the integrity testing of foundations using the CSL testing method.
    This allows to determine the structural integrity and homogeneity of concrete within diaphragm walls, bored piles, drilled shafts, barrettes, concrete piles or augercast piles.

    Tension bar systems
    Dextra’s Tension Bars System is usually purchased complete with fork end clevises suitable for connection to the host structure. Typical applications include hangers and supports, cross bracing and truss stiffening elements.
