Introduction: The Challenge of Processing Thick Coils

In the metal coil processing industry, handling thick or high-tensile materials is no easy to task. Standard regular slitting line often fall short when dealing with:

• Hot-rolled steel over 4mm
• Heavy gauge galvanized coils
• High-strength materials like automotive structural steel

This is where the Heavy-Duty Slitting Line becomes indispensable. These machines are engineered for strength, durability, and accuracy, even under extreme material loads.

 

 

What is a Heavy-Duty Slitting Line?

A heavy-duty slitting line is an industrial machine system designed to cut wide and thick metal coils into narrower strips, which are then rewound into smaller coils. Compared to standard slitting lines, they feature:

 

Feature	Heavy-Duty Slitting Line
Coil Thickness Range	2mm – 12mm+
Coil Weight Capacity	Up to 30 tons or more
Slitting Speed	80 – 150 m/min (optimized for heavy materials)
Structural Frame	Reinforced, vibration-resistant heavy base

 

 

Why Coil Processing Industry Need Heavy-Duty Slitting Lines?

 

For Processing Thick and Hard Materials

Standard slitting line are not built to handle materials like:

• Hot rolled carbon steel
• Pickled and oiled steel
• Mild steel plates
• High-strength low alloy steel

These materials require greater cutting force, stronger blade shafts, and more robust tension control - which only a heavy-duty slitter can offer.

 

For Stable Recoiling and Precision Strip Control

Thicker materials cause more tension and torque during rewinding. Without the right tension brake system and robust recoiler, you risk:

• Coil deformation
• Misalignment of strips
• Overheating in bearings or hydraulic system

 

For Serving Demanding Industries

 

Industry	Material Processed
Automotive Structural Components	3–8mm cold or hot rolled steel
Heavy Machinery Manufacturing	High-tensile thick coil steel
Shipbuilding	Galvanized or hot-dip thick plates
Construction Equipment	Wear-resistant thick carbon steel

 

If you clients requires bulk, strong, durable metal strips, investing in a heavy-duty slitting line ensures high-volume precision proessing.

 

 

In a market where material strength and coil thickness keep rising, a heavy-duty slitting line is a crucial choice. Whether you're serving construction, shipbuilding, or automotive industries, choosing the right slitter determines your throughput, product quality and profiability.
