NUMBERS DONT'S LIE

Design of Structures for Hot Dip Galvanizing

Certain standard practices shall be followed in designing the structures for effective and safe galvanizing coating on structures. In baharain galavanizing factory, We provide total solution to our clients and customers by providing them all technical support and advises, in the initial stage of designing of structures itself , there by achieve the best quality of galvanizing.

Duplex System Of Coating

Applying two coats of paint over hot dip galvanized structure is considered to be the best corrosion protection system for steel structures. It provide barrier protection as well as cathodic protection. Studies have proved that, duplex system of coating doubles the life of steel.

Hot Dip Galvanizing of Concrete Reinforcement Bars

Concrete normally provides corrosion protection to embedded reinforcing steels. However this protection is easily breached by the intrusion of chloride ions and other contaminants in to the concrete due to aggressive environment, poor design or workmanship. In this situation, the steel reinforcement begins to corrode and damage to the concrete is very soon and inevitable.

This is completely eliminated by using hot dip galvanized bars in place of epoxy coated bars. Hot dip galvanizing can be carried out even after cutting and bending of the steel form work.

Life of Hot Dip Galvanized Coatings

The life of galvanized steel depends upon the environment to which the steel is exposed to. In a moderately industrialized environment, galvanized steel has a life of 41 years for a coating thickness of 85 microns. The life of galvanized steel is directly proportional to the coating thickness.
