Parallel Thread Rebar Couplers

ShreeShakti Nextgen offers durable, high-quality Parallel Thread Rebar Couplers with reliable strength and nationwide service.

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.

At Shreeshakti Nextgen Pvt. Ltd., we provide Parallel Threaded Rebar Couplers engineered for strong, durable, and efficient reinforcement bar connections. These couplers are widely used in precast concrete structures, bridges, and high-rise buildings, offering superior strength and ease of installation compared to traditional lapping methods.

Product Features

  • Precision-engineered mechanical splicing system for reinforced concrete structures.

  • Designed for high-performance under static and dynamic loads.

  • Manufactured from high-grade EN8D material to ensure strength and durability.

  • Corrosion-resistant coating for enhanced longevity in harsh environments.

  • Suitable for all standard rebar sizes (as per IS, BS, ASTM, or DIN standards).

  • Quick and easy installation, reducing labor and construction time.

  • Threaded with ISO metric parallel threads to ensure consistent mechanical performance.

Maximum length Capcapacity on TMT Bar 12 Meter

Essential Machines Required On-Site

  • Threading Machine – Precisely cuts parallel threads for seamless splicing.

Bar Preparation

  • The reinforcement bar ends are cut square and threaded using a special threading machine.

  • Threading is done parallel to the bar axis to ensure 100% bar cross-sectional contact.

  • Bars are deburred and cleaned before coupler installation to maintain thread integrity.

  • Shreeshakti’s threading process ensures high precision and alignment for secure splicing.

Key Benefits

  • Time-Saving: Fast and easy installation eliminates the need for lap splicing.

  • Cost-Effective: Reduces bar wastage and saves steel.

  • Space Efficient: Ideal for congested reinforcement zones and seismic applications.

  • High Strength: Achieves full bar break performance, exceeding the strength of parent rebar.

  • Versatile: Suitable for precast, cast-in-place, and retrofitting projects.

  • Reliable: Consistent performance under tensile, compressive, and fatigue loading.

Shreeshakti Nextgen Rebar Coupler Testing

Our couplers undergo rigorous quality control and mechanical testing to ensure superior performance, reliability, and compliance with national and international standards.

EN8D Material Test Parameters:  IS 16172

  • Tensile Strength Test – Verifies the tensile load capacity of the coupler joint.

  • Elongation Test – Measures ductility and the elongation behavior under stress.

  • Location of Fracture Test – Ensures fracture occurs outside the coupler, confirming full bar break.

  • Distance of Fracture from Coupler Test – Validates compliance with code requirements.

  • Slip Test – Measures slippage within the coupler to ensure rigid mechanical bonding.

  • Bend Test – Assesses the coupler’s resistance to bending under field conditions.

  • Yield Stress Test – Confirms that the coupler assembly performs beyond the yield point of the rebar.

Optional Advanced Testing (As per client requirement)

For critical applications such as high-rise, infrastructure, or seismic zones, we also offer:

  • Cyclic Tensile Test – Assesses coupler performance under repeated tension loading.

  • Low Cycle Fatigue Test – Simulates structural behavior under limited high-stress repetitions (e.g., during earthquakes).

  • High Cycle Fatigue Test – Evaluates long-term durability under frequent low-amplitude stresses (e.g., bridges, towers).
