Tensile testing machine for prestressing steel strand; with standard fixtures it also runs tensile, compression, bending and shear tests on metals.
Overview
This series is mainly used for steel strand tensile testing; with standard fixtures it can also perform tensile, compression, bending and shear tests on metals. The four-column double-space models include WEW microcomputer hydraulic universal and WAW electro-hydraulic servo universal testers; the three-column single-space upper-cylinder model is an electro-hydraulic servo type. All are equipped with hydraulic wedge grips and a dedicated digital extensometer with 500/600 dual gauge lengths, which eliminates strand rotation during stretching for accurate axial deformation measurement.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• High measurement accuracy with stable repeatability
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Steel Strand Tensile Testing Machine comply with?
A1: The Steel Strand Tensile Testing Machine is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Steel Strand Tensile Testing Machine be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
