Galvanized steel coils
Troubled by insufficient slitting precision and zinc layer peeling of galvanized steel coils? GNEE optimized the slitting process, equipped with special equipment and tools, creating an efficient and precise coil slitting solution.
We can process galvanized steel coils with width 800-1800mm and thickness 0.2-6.0mm, with slitting width tolerance ±0.1mm, supporting batch processing and on-time delivery to meet personalized cutting needs.
Slitting of galvanized steel coils is a key link in subsequent processing. Traditional processes are prone to burrs and zinc layer damage. The optimized process can effectively avoid these pain points and ensure product consistency.

Key Points of Slitting Process Optimization
Targeting the characteristics of galvanized steel coils, upgrades have been achieved in three aspects: equipment, tools and processes:
|
Optimization Dimension |
Pain Points of Traditional Process |
Advantages of Upgraded Scheme |
Processing Effect |
|---|---|---|---|
|
Tool Configuration |
Ordinary tools wear easily, resulting in serious cutting burrs |
Cemented carbide tools, precision tool grinding process |
Burr ≤0.05mm, no zinc layer peeling |
|
Tension Control |
Uneven tension causes coil deformation and deviation |
Intelligent tension control system, real-time adjustment |
Flat cutting, no wavy edges |
|
Dust Removal Treatment |
Zinc powder residue affects subsequent processing |
Dual dust removal by high-pressure air blowing + vacuum adsorption |
Clean surface, no zinc powder residue |
