GW-40B reverse (re-bend) testing machine for reinforcing bars and welded bars, checking ductility under repeated bending.
Overview
The GW-40B GW-40B Rebar Reverse Bending Testing Machine is used for bending tests of steel for reinforced concrete and welded steel bars. It can detect plastic deformation capacity, bending toughness and fatigue resistance of steel bars under repeated bending. It is suitable for iron and steel enterprises, building materials, highway and transportation, quality inspection institutions and laboratories. The machine adopts mechanical transmission and can realize forward and reverse bending. It features compact structure, convenient operation, high test efficiency and complete safety protection.

FAQ
Q1: What standards does the GW-40B Rebar Reverse Bending Testing Machine comply with?
A1: The GW-40B Rebar Reverse Bending 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 GW-40B Rebar Reverse Bending 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.
