Features of ductile iron Features of ductile iron polespoles
1.1. Strength – Has similar physical Strength – Has similar physical strength of steel strength of steel
2.2. Durability – Corrosion resistance of Durability – Corrosion resistance of iron which is superior to steeliron which is superior to steel
3.3. Cost effective Cost effective
4.4. Ease of installation – Same as Steel, Ease of installation – Same as Steel, similar to woodsimilar to wood
5.5. GREEN product, recyclable and GREEN product, recyclable and made from recycled steelmade from recycled steel
Advantages of ductile ironAdvantages of ductile iron High strength-to-weight ratioHigh strength-to-weight ratio Good surface definition and finish Good surface definition and finish Impervious to rot, insects and woodpeckersImpervious to rot, insects and woodpeckers Purchase price is very competitive with steel Purchase price is very competitive with steel Corrosion resistant – Iron water pipe is Corrosion resistant – Iron water pipe is
