What's the Difference Between Single-Wire and Double-Wire Automatic Stirrup Benders? Application Scenarios Explained

As the construction industry moves toward higher efficiency and automation, automatic stirrup benders have become essential equipment in steel bar processing. Among them, single-wire and double-wire stirrup benders are two of the most common types—but what exactly sets them apart? And more importantly, which machine is best suited for your production needs?

In this article, we explore the core differences between single-wire and double-wire stirrup benders, and provide practical recommendations for their application in different jobsite or factory environments.

1. What Is a Single-Wire Stirrup Bender?

A single-wire automatic stirrup bender feeds and processes one steel wire at a time, typically ranging from 5 mm to 13 mm in diameter. It is ideal for standard rebar processing with lower to medium daily output requirements.

Key Features:

• Processes 1 wire at a time

• Simpler structure, lower maintenance

• More precise bending on small radius shapes

• More economical for small to medium workshops

---

2. What Is a Double-Wire Stirrup Bender?

A double-wire stirrup bender feeds and bends two wires simultaneously, effectively doubling the productivity. These machines can handle wire diameters up to 12 mm × 2 wires and are suitable for large-scale construction or prefab plants.

Key Features:

• Processes 2 wires at once

• Up to 2× output efficiency

• Slightly larger footprint and power consumption

• Requires more precise synchronization and calibration

4. Which Machine Fits Which Scenario?

✅ Choose a Single-Wire Bender if:

• Your production volume is below 5 tons/day

• You focus on custom-shaped stirrups or multiple shape types

• Your workshop space is limited

• You want a lower-cost machine with easy maintenance

✅ Choose a Double-Wire Bender if:

• You process large quantities of standard stirrups

• Your daily output target is 5–10+ tons

• You operate a prefabricated building factory or rebar processing plant

• Labor cost is high, and efficiency is a top priority
