LIFE CYCLE ADVANTAGES OF GBARZ (GALVANIZED RE-BARS)
Let’s understand the life cycle cost by using three types of coated TMT, in the same environment, at the average cost in Rupees Per Metric Ton of Steel.

*Only if the coating is not damaged before or while concreting.
For simplicity, we have not calculated inflation and other hidden cost like replacing interior appearance, additional of steel etc. The maintenance cost of fusion bonded epoxy coating & painting is much more in the long run, while galvanizing is virtually maintenance free.
