MBT Rebar Couplers

Premium MBT Couplers for strong, threadless rebar connections—durable, corrosion-resistant, and easy to install.

Applications:

  • Commercial Buildings: Ideal for constructing high-rise buildings, shopping malls, and office complexes

  • Infrastructure Projects: Widely used in the construction of bridges, tunnels, and highways.

  • Industrial Facilities: Essential for the framework of factories, warehouses, and production plants.

  • Residential Projects: Provides robust support for modern residential buildings and multi-story apartments.

ShreeShakti Nextgen produces premium MBT Couplers, offering a hassle-free solution for joining reinforcement bars without threading or welding. Crafted from high-strength EN8D steel, these couplers ensure durability, corrosion resistance, and long-lasting performance. Designed to meet industry standards, they provide secure and efficient connections, making them ideal for demanding construction projects. With a simple installation process and availability in multiple sizes, MBT Couplers are the perfect choice for reinforcing structures with ease and reliability.

Product Features

  • No threading or bar rotation required, ideal for retrofit and congested site conditions.

  • Constructed from premium-grade EN8D steel for strength, durability, and corrosion resistance.

  • High-strength bolts create a solid mechanical grip on the rebar surface.

  • Accommodates misaligned or irregularly cut bar ends.

  • Available in multiple sizes to suit rebar diameters from 12mm to 40mm (or custom).

  • Suitable for both tension and compression zones.

  • Quick and easy installation using standard hand tools – no special machinery required.

Essential Machines Required On-Site

  • Impact Wrench: Power tool used to tighten MBT coupler bolts quickly and accurately. Speeds up installation.
  • Torque Wrench: Tightens shear bolts until heads snap at preset torque for a secure, consistent connection.

Bar Preparation

  • Simply cut the rebar square at the end — no threading, forging, or bar-end treatment is needed.

  • Insert both rebar ends into the MBT Coupler until they meet at the center stop.

  • Tighten the shear-head bolts using a calibrated torque wrench until the heads shear off, indicating proper installation.

  • No bar rotation or threading ensures suitability for projects with fixed or congested bars.

Key Benefits

  • Threadless Connection: No specialized threading machinery required.

  • Time-Saving: Ideal for quick on-site connections and repairs.

  • Retrofit Friendly: Excellent for upgrades and bar extensions in existing structures.

  • Secure Load Transfer: Designed to exceed the tensile strength of the parent bar.

  • Minimal Bar Preparation: Reduces labor and installation errors.

  • Versatile Applications: Perfect for bridges, seismic retrofits, precast elements, and rebar extensions.

Shreeshakti Nextgen Rebar Coupler Testing

To ensure every MBT coupler delivers high performance and structural safety, we conduct extensive quality testing on all batches.

Standard Testing Protocols

  • EN8D Material Test – Confirms raw material quality and mechanical properties.

  • Tensile Strength Test – Ensures the splice can carry full bar strength.

  • Elongation Test – Verifies ductility and performance under tensile stress.

  • Location of Fracture Test – Confirms bar-break performance (outside the coupler zone).

  • Distance of Fracture from Coupler – Ensures code-compliant performance.

  • Slip Test – Measures movement under axial loading; ensures minimal displacement.

  • Bend Test – Validates resistance to bending and lateral forces.

  • Yield Stress Test – Assesses behavior beyond the yield point under applied loads.

Additional Optional Tests (Available on Request)

For special infrastructure and seismic projects, we offer:

  • Cyclic Tensile Test – Measures performance under alternating stress conditions.

  • Low Cycle Fatigue Test – Simulates extreme events like earthquakes.

  • High Cycle Fatigue Test – Tests long-term durability under repeated small stresses (e.g., bridges, rail infrastructure)
