- Wear resistance: 1.2377, 1.2344 and 1.2990 for consistent performance in long runs.
- Coating protection: vulcanised polyurethane spacers that guide the material without damaging the zinc layer.
- Precision: parallelism and flatness tolerances (±0.001) for correct strip stacking.
Features of our knives for cutting galvanised materials
Cutting galvanised sheet presents unique challenges that we solve with:
- Specific material: alloys designed for zinc coatings, which prevent premature edge wear.
- Custom heat treatments: hardness adjusted to withstand friction without losing cutting ability.
- Process optimisation: a clean cut reduces zinc residue and extends maintenance intervals.
Advantages of Teco Knives blades for galvanised steel
- Maximum productivity on high-speed lines.
- Lower cost per cut: material and hardness that extend service life.
- Tear-free cutting: protects the sheet coating.
- Bespoke for slitting, guillotine shears and chip-breaker blades for galvanised material.
Factors to consider when cutting galvanised sheet
Before manufacturing your knife we analyse three variables:
- Zinc coating thickness: defines the knife steel.
- Line speed: toughness adjusted to prevent edge overheating.
- Fit tolerances: precision grinding prevents zinc from adhering to the knife faces.
