The Steel bar thread rolling machine GLUS-AGB-40 is the latest-generation equipment engineered by GLUS for producing high-precision cold-forged rebar threads. Designed for heavy-duty construction, large infrastructure, and high-rise building projects, the AGB40 delivers unmatched threading accuracy, fast production speed, and superior reliability in mechanical splicing.

By combining rib-peeling and thread rolling in one automatic process, the AGB40 ensures consistent thread quality and guarantees mechanical splices that match or exceed the tensile strength of the parent rebar.

Key Features

1. One-Step Automatic Rib-Peeling & Thread Rolling

The machine removes longitudinal and transverse ribs and then cold-rolls threads in one clamping, ensuring
✔ High-precision threads
✔ Stable dimensional tolerance
✔ Stronger cold-forged thread structure
✔ Higher splice strength than cut threads

2. High Production Speed

The machine head expands radially after rolling and returns rapidly, significantly reducing cycle time and improving efficiency for mass production.

3. Wide Processing Range

• Suitable for HRB400 / HRB500 and HBB400 / HBB500 rebars

• Diameter range: Ø16–Ø40 mm

• Foreign rebar grades may be used after suitability testing

4. Pneumatic Semi-Automatic Control System

A robust mechanical + pneumatic system ensures:

• Stable clamping force

• Smooth forward/reverse feed

• Reliable automation

• Simple and safe operation

5. Precision Thread Quality

Three synchronized rolling wheels ensure:

• Uniform thread shape

• Smooth surface

• Stable pitch and diameter

• High repeatability even with variable rebar shape

6. Heavy-Duty & Durable Design

• High-strength frame

• Industrial-grade gearbox

• Automatic lubrication & cooling

• New-generation high-force pneumatic vice (no slipping)
