ForgedNEX cold-forged threaded rebar coupler system

Konnexa Forged NEX Coupler Series

ForgedNEX™ is Konnexa's premium cold-forged threaded rebar coupler system, designed to deliver a full-strength mechanical splice for reinforced concrete construction. The reinforcing bar ends are cold forged prior to threading — increasing the effective bar diameter and preserving the parent bar's core cross-sectional area.

This process enhances thread integrity, optimizes load transfer, and ensures superior tensile, compression, and fatigue performance under the most demanding structural conditions.

Applications Examples

The Konnexa advantage - Switching from traditional lapping to the Konnexa Series typically delivers a 15-20% reduction in total steel consumption while significantly shortening structural installation timelines.

Technical Specifications

Core features engineered for extreme performance

Parallel Profile

Increases local grain density via cold-working, preserving 100% of the parent rebar's nominal cross-section.

Zero-Slip Engineering

Delivers ultra-low slip metrics (< 0.1 mm residual movement), optimizing immediate load transfer under working loads.

Cyclic Endurance

Safely withstands high-cycle elastic fatigue and low-cycle reverse-plastic loading — fail-safe seismic performance.

Bar Compatibility

Engineered for high-yield reinforcement bars — Fe 550D, Fe 600, Grade 75/80 — from 16 mm to 40 mm diameters.

Material Grade

Fabricated from high-tensile structural steel (EN8D / equivalent carbon-alloy grades) for extreme fatigue resistance.

Full Traceability

100% traceable through unique batch & product identification, supported by MTC and NABL-accredited test reports.

Bar Preparation Sequence

Three Steps to a Full-Strength Splice

A single threading machine and a single operator are all that is required for rebar preparation — peeling, forging, and rolling performed in sequence, directly on site.

Bar-End Preparation

The end of the reinforcing bar is precisely squared and peeled to a controlled diameter — preparing a clean, uniform surface for threading.

Forge

Bar ends are cold forged prior to threading — increasing the effective bar diameter and preserving the parent bar's core cross-sectional area.

Cold Roll-Threading

The peeled end of the reinforcing bar is then threaded by cold rolling. No parent material is cut away — grain flow is preserved, so the bar keeps its full strength.

Coupler Engagement

The ForgedNEX™ sleeve is threaded onto both prepared bar ends and tightened with calibrated torque — completing a full-strength mechanical splice in seconds.
