Cut To Length Line (CTL) – Precision Sheet Cutting Solution

What Is a Cut To Length Line?

A Cut To Length Line (CTL Line) is a metal processing system used to uncoil steel coils, level the material, cut it into required lengths, and stack finished sheets automatically.

It is widely used for processing:

✅ Carbon Steel Sheets
✅ Stainless Steel Sheets
✅ Galvanized Steel Sheets
✅ Aluminum Coils
✅ Pre-painted Steel Coils (PPGI/PPGL)

The main purpose of a cut-to-length line is to transform large steel coils into flat sheets with accurate length, excellent flatness, and clean edges.

Main Equipment of a Cut To Length Line

A typical CTL line consists of the following equipment:

1. Coil Loading Car

Transfers steel coils safely onto the decoiler.

2. Hydraulic Decoiler

Supports and uncoils the steel coil continuously.

3. Pinch Roller & Leveling Machine

Feeds the strip forward and removes coil set or waviness to improve sheet flatness.

4. Servo Length Measuring System

Measures sheet length precisely according to production requirements.

5. Hydraulic or Flying Shear

Cuts the strip into preset lengths with high accuracy.

6. Conveyor Table

Transports cut sheets smoothly to the stacking section.

7. Automatic Stacker

Collects and stacks finished sheets neatly for easy handling and packaging.

8. Electrical Control System

PLC and HMI control the entire production process, providing easy operation and stable performance.

How to Choose the Right Cut To Length Line?

Selecting the proper CTL line depends on several key parameters:

Material Type⚙️

Different materials require different machine configurations.

• • Carbon Steel
• • Stainless Steel
• • Aluminum
• • Galvanized Steel

Material Thickness📐

Thickness directly affects leveling and cutting capacity.

For example:

• Thin Gauge: 0.3–3.0 mm
• Medium Gauge: 3.0–8.0 mm
• Heavy Gauge: 8.0–20.0 mm

Coil Width✂️

Determine the maximum strip width to be processed.

Typical widths include:

• 600 mm
• 1250 mm
• 1600 mm
• 2000 mm

Coil Weight🔧

The decoiler capacity must match the maximum coil weight.

Common capacities:

• 10 Tons
• 15 Tons
• 20 Tons
• 30 Tons

Required Production Speed📈

Higher production speed requires more advanced automation and control systems.

Length Accuracy Requirement✂️

If high precision sheets are required, servo-controlled measuring systems are recommended.
