High-Speed Fiber Laser Cutting Machine for Galvanized Sheets & Plates
Our advanced fiber laser cutting machine is specially engineered for galvanized iron (GI) sheet cutting, delivering high-speed cuts with minimal zinc coating damage and excellent corrosion resistance.
Designed for HVAC, automotive, construction, and industrial fabrication, this machine efficiently handles GI, PPGI (pre-painted galvanized iron), and HDG (hot-dip galvanized) sheets with consistent performance.
Whether you manufacture ducting, roofing panels, automotive parts, or electrical enclosures, this solution ensures clean cuts while preserving the zinc coating integrity.
Why Laser Cutting for Galvanized Iron (GI)?
Galvanized iron sheets are widely used in HVAC, construction, automotive, and electrical industries due to their excellent corrosion resistance. Traditional cutting methods can damage the protective zinc coating, reducing corrosion protection.
Advantages of Laser Cutting for GI Sheets
Fiber laser cutting provides precise, high-speed cuts on galvanized sheets with minimal heat-affected zones, preserving the zinc coating integrity. Oxygen-assisted cutting delivers fast speeds for thick GI plates, while nitrogen cutting provides cleaner edges for thin sheets and PPGI materials.
Applications
GI laser cutting is ideal for HVAC ducting, roofing panels, automotive body parts, electrical enclosures, construction components, agricultural equipment, and industrial fabrication requiring corrosion-resistant materials.
Galvanized Sheet Types Compatibility
Our fiber laser cutting machines handle various galvanized sheet types for industrial and construction applications.
GI (Galvanized Iron) - Hot Dip
Hot-dip galvanized iron sheets with zinc coating (Z120-Z275). Excellent corrosion resistance for outdoor and industrial applications. Most common GI grade in India.
- Coating: Z120, Z180, Z275 (g/m²)
- Cutting Speed: 12–20 m/min (1mm)
- Recommended Gas: Oxygen (fast) / Nitrogen (clean)
- Max Thickness: Up to 25mm (12kW)
PPGI (Pre-Painted Galvanized Iron)
Color-coated galvanized sheets with paint/polymer coating. Used in roofing, wall cladding, and decorative applications. Requires nitrogen cutting to prevent paint damage.
- Base: GI + Paint/Polymer coating
- Cutting Speed: 10–16 m/min (1mm)
- Recommended Gas: Nitrogen (mandatory)
- Max Thickness: Up to 3mm (6kW)
Electro-Galvanized (EG)
Thin zinc coating applied by electroplating. Used in automotive, appliances, and electronics. Provides smooth finish and good paintability.
- Coating: Thin zinc layer (electroplated)
- Cutting Speed: 14–22 m/min (1mm)
- Recommended Gas: Nitrogen / Oxygen
- Max Thickness: Up to 6mm (8kW)
