Why Material Type Matters in Coil Processing
In the metal coil processing industry, understanding the material you're working with is essential to achieving high precision, efficiency, and durability. Two of the most common coil materials are stainless steel and galvanzied steel - but each brings its own unique challenges and demands different machine configurations.
Knowing how to select the right slitting lien or cut to length line for these materials can greatly reduce downtime, improve output quality.

Processing Challenges Comparison
1. Stainless Steel Coil Processing Challenges
Stainless steel is much harder to shear, which wears blades quickly and requires stronger blade shafts and high-precision arbors.
Susceptible to scratches and dents, meaning film laminators or felt tension pads are often necessary to protect the surface.
Burr formation is a risk if blade celarance or blade sharpness is not properly maintained.
Higher friction during slitting line or shear creates heat buildup, which can cause material distortion if not controlled.
2. Galvanzied Steel Coil Processing Challenges
Improper handling or sharp blade angles can crack the zinc coating, reducing corrosion protection.
Easier to slit and cut, but telescoping or edge curl can occur without proper tension control.
Zinc particles may accumulate, requiring anti-dust systems or frequent cleaning.
Machine Selection Tips by Material
For Stainless Steel Slitting & CTL Lines
- Machine Frame: Reinforced frame with anti-vibration support, capable of sustaining torque under high tension.
- Tension Pads: Prefer felt tension devices for surface protection
- Film Laminators
For Galvanized Steel Slitting & CTL Lines
- Tension Control: Use servo-controlled tension roll to avoid telescoping or curl
