Product Description

Product Description:

Galvanized Steel is the one, that’s been covered with a layer of zinc metal. During galvanizing, 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 outdoor environments.Apart from preventing water corrosion, it is equally effective in dry & indoor environments also.

Galvanized Pipes & Tubes has long been one of the most used building materials in the world. For decades, designers, builders & consumers seeking long term structural performance, in the tuff outdoor applications, have turned to zinc coated steel pipes.Galvanized Pipes resist the attack of wild, water & road salts.
