GW-40F Steel Bar Bending Testing Machine 6–40mm

Description

GW-40F Steel Bar Bending Testing Machine for Rebar 6–40mm

 

The GW-40F Steel Bar Bending Testing Machine handles rebar diameters from 6 mm to 40 mm and delivers accurate, repeatable bending results for construction quality control. Civil engineers and material testing laboratories across Bangladesh use this machine to verify rebar ductility and conformance before deployment in structural projects. The motorized bending head rotates to precise angles and stops automatically, eliminating operator error. Furthermore, the robust steel frame withstands continuous heavy-duty use without deformation. Whether you test on a project site or in a permanent lab, the GW-40F meets ISO and ASTM rebar bending standards and speeds up your workflow significantly.

 

Key Features

• Handles all common rebar diameters from 6 mm up to 40 mm in a single machine
• Motorized bending head rotates to preset angles — 90°, 135°, and 180° — and stops automatically
• Heavy-duty cast iron and structural steel frame sustains full-load operation without flex
• Forward and reverse rotation switch allows quick unbending for sample removal
• Interchangeable bending pins and rollers accommodate multiple bar sizes
• Overload protection relay cuts power automatically when load exceeds the rated limit
• Compact footprint fits both permanent lab benches and mobile site setups
• Simple push-button control panel reduces operator training time

Frequently Asked Questions

Question 01: What rebar sizes does the GW-40F Steel Bar Bending Testing Machine handle?

Ans: The GW-40F handles all standard rebar diameters from 6 mm to 40 mm using interchangeable bending pins and rollers included with the machine.

Question 02: Which international standards does this machine meet?

Ans:The GW-40F complies with ISO 15630-1, ASTM A370, and BS 4449 rebar bending test requirements — all standards widely accepted on Bangladesh government and private projects.

Question 03: Does the machine bend rebar in both directions?

Ans: Yes. The forward and reverse rotation switch lets operators bend and then unbend the rebar sample, which the ASTM and ISO re-bending test procedures require.

Question 04: What power supply does this machine need?

Ans: The standard GW-40F runs on 380V / 50Hz three-phase power. ASTZBD also supplies a 220V single-phase version for sites without three-phase connections — ask our team when ordering.

Question 05: Do you provide installation and training in Bangladesh?

Ans: Yes. ASTZBD sends a technical engineer to your site for machine installation, electrical connection, and operator training anywhere in Bangladesh.
