PL-300S fatigue testing machine for steel bars, strands and metal components: high/low-cycle fatigue and sinusoidal loading.
Overview
The PL-300S PL-300S Rebar Fatigue Testing Machine is mainly used for axial tensile, compressive and fatigue performance testing of steel bars, steel strands and metal components. It can perform high-cycle fatigue, low-cycle fatigue, pulsating load, sinusoidal load and cyclic loading tests. It is suitable for iron and steel enterprises, machinery manufacturing, automobile manufacturing, building materials, quality inspection institutions and scientific research laboratories. The machine adopts electro-hydraulic servo or microcomputer controlled closed-loop loading. It features high test accuracy, stable loading, flexible waveform control and complete data acquisition.

FAQ
Q1: What standards does the PL-300S Rebar Fatigue Testing Machine comply with?
A1: The PL-300S Rebar Fatigue 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 PL-300S Rebar Fatigue 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.
