RNW PACIFIC ERW GI PIPES

Galvanized Iron Steel Pipes are covered with a layer of zinc metal. During hot-dipped galvanization, steel is immersed in a molten zinc bath, ensuring a tough, uniform barrier coating. Zinc’s natural corrosion resistance provides long-term protection, even in exposed environment. Apart from preventing water corrosion, it is equally effective in dry environment.

BENEFITS OF RNW PACIFIC ERW BI PIPES
Long Life
The life expectancy of galvanized coatings on typical structural members is far in excess of 50 years in most rural environments, and 20 to 25 years plus, even in severe urban and coastal exposure.
Less Maintenance
Galvanizing is almost invariably the cheapest in the long term (because it lasts longer and needs less maintenance). Maintenance causes problems and adds to costs when structures are located in remote areas, and when plant shutdown is involved.
Reliability
Coating life and performance are reliable and predictable.
Complete protection
Every part of a galvanized article is protected, even recesses, sharp corners and inaccessible areas. No coating applied to structure or fabrication after completion can provide the same protection.
