🔍 Wire Galvanizing Calculator: How Chakan Factories Use Zinc Thickness
Chakan MIDC wire factories face ₹50K/week dispatch rejections due to zinc coating failures. IS 4759:2023 mandates minimum 40μm thickness for 5.5mm wire - but 45% fail first test.
⚖️ Why Factories Measure Coating Weight g/m²
- 450 g/m² = Perfect 50μm both sides (ASTM A123 standard)
- Hot bath 460°C = 20% thicker coating automatically
- 8sec immersion = Industry sweet spot
- Line speed 30m/min = Production optimized
🚨 Common Zinc Bath Problems + Solutions
- Too thin (30μm): Cold bath → Increase to 450°C
- Too thick (80μm): Slow line → 35m/min speed
- Uneven coating: Dirty flux → Clean zinc kettle
- Black spots: High iron → Pure zinc 99.99%

📐 Galvanizing Formula:
Surface Area = π × (D/1000) × L (m²)
Coating Weight = 450 × TempFactor × TimeFactor (g/m²)
Thickness(μm) = CoatingWeight ÷ SG (7.14)
IS4759 Check = Thickness ≥ 6000/D(mm)
