CE Certified Rebar Couplers: Specifications, Parameters, and Compliance for Global Projects
CE Certified Rebar Couplers: Specifications, Parameters, and Compliance for Global Projects
CANGZHOU BARTECH CONSTRUCTION MATERIAL CO. LTD. is a leading global supplier of rebar couplers and rebar threading machines based in China. Since 2008, the company has specialized in mechanical rebar connection technologies including Parallel Thread Rolling, Parallel Thread Upsetting, and Cold Pressing. This article provides the technical specifications, compliance certifications, and selection criteria for their rebar coupler product line, which is CE and ISO 9001:2015 certified.
Problem Definition
Construction projects worldwide require rebar connections that meet strict strength and durability standards. Traditional lap splicing is space-consuming and material-intensive, while welding introduces fire and quality risks. Procurement managers and engineers need rebar couplers that guarantee mechanical performance, are backed by recognized certifications like CE and ISO, and provide clear technical parameters for project specification compliance.
Industry Background
The global construction industry increasingly adopts rebar mechanical couplers to improve structural integrity, reduce steel waste, and speed up erection. Standards such as CE marking for the EU market and ISO 9001 for quality management systems are essential for international acceptance. CANGZHOU BARTECH's product range addresses these requirements across four main joining technologies.
Detailed Solution
Certification Overview
All rebar couplers and threading machines from CANGZHOU BARTECH are covered by a CE certificate (certification number Nr.SC-PSC-4-2025-12-14, standard MTZ202512021CPR, valid until 2030-12-03) issued by CERTIFICATION CENTER for the EU market. Additionally, the company holds ISO 9001:2015 certification (certificate number 31623Q10713R1S, standard GB/T19001-2016 / ISO9001:2015, valid until 2026-12-21) issued by CEOC Testing & Certification Center (Beijing) Co., Ltd. for global operations.
Product Series and Parameters
The rebar coupler range includes four main types, each available in models 16 to 40 (covering diameters 16mm to 40mm):
- Rolled Thread Rebar Coupler (carbon steel 45# or alloy steel 40CR): Parallel thread rolling technology. Example for model 25: OD 38mm × Length 62mm, Thread M25.6×3.0 60°.
- Upset Forged Rebar Coupler (carbon steel 45# or alloy steel 40CR): Requires upsetting machine. Example for model 25: OD 40mm × Length 60mm, Thread M30×3.5 60°.
- Cold Extrusion Rebar Coupler (carbon steel Q355B): Pressing connection. Example for model 25: OD 45mm, Length 150mm, Thickness 7.4mm.
- One-Touch Rebar Coupler (alloy steel 40CR): Quick connection. Example for model 25: OD 56mm, Length 143mm.
Supporting Equipment
Bartech provides complete systems including rebar threading machines (models: CBT40A, CBT40L, 40AO, 40MO), rebar upsetting machines (Auto 36s, Auto 50s), rebar thread cutting machine MQ40, rebar coupler pressing machine CBT32, and rebar electric torque wrenches BOC 8-32 and BOC 8-42 (CE certified). These machines are designed for construction projects, high buildings, airports, high-railway stations, and sea-cross bridges.
Step-by-Step Selection Guide
- Identify rebar grade and diameter (400/500 grade, 16–40mm).
- Choose connection type based on project needs: rolled thread for standard use, upset for high-strength, cold press for on-site simplicity, one-touch for rapid assembly.
- Verify certification requirements — CE for EU projects, ISO 9001 for global quality assurance.
- Select matching equipment — threading machine for rolled/upset, pressing machine for cold extrusion, electric wrench for one-touch.
- Order samples — stock couplers have no minimum order quantity.
Use Cases
- High-Rise Buildings: Rolled thread and one-touch couplers for fast erection. Used in Vietnam and Middle East projects.
- Bridges & Sea-cross Projects: Upset forged couplers provide full-strength connection. Supplied to Kuwait and Saudi Arabia.
- Metro & Tunnel Construction: Cold extrusion couplers allow installation in confined spaces without fire risk.
