Surya Enginering

Surya Engineering is a manufacturer of Rebar Couplers which are use to join the reinforcement bars end to end. Couplers are an efficient alternative for traditional lap splice or overlapping joints. Cost benefit analysis show that use of threaded rebar couplers is a cost effective method as compared to old method of lap splicing / overlapping joints.
Rebar Couplers are readily available for any rebar diameter ranging from 16 mm to 40mm. Surya Engineering can customize our products to meet your specific requirement.

High cycle fatigue test

 

High cycle fatigue testing is typically conducted on specimens in load/stress control to develop Stress-Life (S-N) Curves.  An S-N Curve is generated by testing samples at a constant load/stress and recording the number of cycles to failure.  The data is then compiled and a best trend fit is applied.  This establishes a relationship between a particular load/stress level and the fatigue life of the material.

Low cycle fatigue test

 

There are two types of fatigue tests namely low cycle fatigue test and high cycle fatigue test. All reinforcement couplers should be able to satisfy the requirement for low cycle fatigue tests. The mechanical splice should withstand 10 000 cycles of alternating tension and compression load when tested by a standard method.

An MBT Coupler is a high-strength mechanical connector used in reinforced concrete construction to join reinforcing steel bars (rebar) end-to-end or in lap-free splices. Designed for speed, reliability, and structural integrity, MBT Couplers eliminate the need for traditional rebar overlapping, reducing material waste and labor costs while enhancing load transfer between bars.

Key Materials Used in MBT Couplers:

1. Coupler Body:

   • Carbon Steel (Grade 8.8 or 10.9): High-tensile carbon steel provides exceptional strength and durability, ensuring reliable load transfer between rebars.

   • Stainless Steel (Grade 304/316): Used in corrosive environments (e.g., marine, chemical plants) for superior rust resistance.

   • Galvanized Steel: Zinc-coated for added corrosion protection in standard construction applications.

2. Threads:

   • Case-Hardened Steel: Precision-cut threads are hardened to resist wear and deformation during installation.

   • Alloy Steel (Cr-Mo): Chromium-molybdenum alloy enhances thread strength and fatigue resistance under dynamic loads.

3. Sealing Components (Optional):

   • EPDM/Neoprene Gaskets: Watertight seals prevent moisture ingress in joints exposed to water or humidity.

   • Nylon Inserts: Protect threads during transport and handling.

4. Coatings/Treatments:

   • Hot-Dip Galvanizing: For extended corrosion resistance.

   • Epoxy Coating: Used in aggressive chemical environments.

   • Zinc-Aluminum Coating: Combines galvanic and barrier protection.

Benefits of MBT Coupler Materials:

1. High Strength-to-Weight Ratio:

   • Carbon/alloy steel ensures tensile strength up to 1,000 MPa, matching or exceeding rebar performance.

2. Corrosion Resistance:

   • Stainless steel or galvanized coatings extend lifespan in harsh environments.

3. Durability:

   • Resists deformation, vibration, and seismic forces due to robust material engineering.

4. Compatibility:

   • Matches common rebar grades (e.g., ASTM A615, BS 4449, IS 1786).

5. Ease of Installation:

   • Pre-threaded couplers with standardized threads simplify on-site assembly.

Applications:

• High-Rise Buildings: Lap-free column/wall reinforcement.

• Bridges & Tunnels: Corrosion-resistant splices in critical joints.

• Industrial Floors: Rapid installation for large-scale slabs.

• Seismic Zones: Reliable load transfer in earthquake-resistant structures.

Compliance & Standards:

• Meets ISO 15835, ASTM A1034, and BS 8110 for mechanical splices.

• Certified for use in LEED projects due to reduced material waste.

Why Choose MBT Couplers?

• Cost Savings: Eliminates rebar overlap (up to 40% material reduction).

• Time Efficiency: Faster installation vs. traditional lapping.

• Structural Integrity: Full tension/compression capacity with no weak points.
