Preparation

When products arrive at our facility, they are inspected for drainage, venting, as well as other designs requirements to ensure that they meet our requirement standards.  Adopting the proper design practices ensure optimum quality galvanizing, minimum cost and faster delivery.  

Pickling & Fluxing

During pickling, products are immersed in a dilute solution of hot sulfuric acid to thoroughly remove surface rust and scale.  

Fluxing creates a protective barrier to prevent the steel from oxidizing before taking a zinc bath, while simultaneously facilitates the metallurgy reaction between zinc and steel. In addition, ​it also removes any oxides that may have developed at the pickling stage,  

 
 
 

Hot-Dip Galvanizing

The product is dipped into the molten zinc bath at a temperature of approximately 450° Celsius whereby the zinc reacts with the iron in the steel to form a series of metallurgically bonded zinc-iron intermetallic alloy layers

 

Quality Inspection

Coating thickness is measured accurately with electronic gauges to comply with the standard specification.  Coating quality is also both visually and physically inspected.  

"Hot dip galvanizing has long been seen as the most environmentally-friendly finishing process available to prevent corrosion.

It is highly sustainable and produces minimal waste."

THE  PROCESS

"Simply Four"

There are four steps in Hot-Dip Galvanizing process and we call it as the "Simply Four" process.  To achieve an optimal coating result, practicing the following process is essential: 

Galvanizing Benefits

Life expectancy of galvanized coatings lasts in excess of 50 years or more

The abrasion and corrosion resistance galvanized coating provides an easy to clean and hygienic surface

A metallurgical process which forms a permanent bonded tough alloy coating and provides an outstanding resistance to physical damage

Galvanizing is carried out to ASTM A123 and ISO specification, with standard, minimum coating thicknesses applied, allowing coating life and performance both reliable and predictable.

Lowest overall cost compared to other coating methods

A quick and time-saver coating process

The coating durability makes it abrasion resistant and absorbs impact, resulting in less likely the need for maintenance

Any poorly accessible areas of a structure, even recesses and sharp corners, will get a complete galvanized coating protection
