HOT DIP GALVANIZING
WHAT
Hot dip galvanizing is the best protective coating solution available for steel-based materials. Hot dip galvanized steel is a proven performer as a durable, low maintenance, sustainable products. Our galvanized finishes can be applied to residential and commercial constructions, marine applications, agricultural equipment, engineering infrastructures, and so many more!
HOW
Hot dip galvanizing is a process where steel articles are immersed in a bath of molten zinc to cause an alloying reaction between steel and zinc. This process coats all joins, seals, welds and corners of the object while penetrating any recesses in the steel to provide full corrosion resistance.
WHY
Hot dip galvanizing is the best protective coating technology for steel. A 150 year old practice, it uses zinc to protect steel from corrosion - providing long life, durability and beauty. It also matches the design and handling characteristics of steel.
As galvanizing delivers a predictable, engineered performance, it helps to effectively reduce the cost of asset management by virtually eliminating disruptive maintenance. Hot Dip Galvanizing also meets all environmental responsibilities with processes that have low wastage, low emission and have high recyclability and reusable properties.
The Process
The Benefits
A one-time process, hot dip galvanizing ensures maintenance-free use of steel. The use of hot dip galvanizing for structural steel protection gives 10 important, measurable benefits:
Lowest first cost
Compared to many other protective coatings for steel, hot dip galvanizing has the lowest first cost of protection.
Super long life
The life expectancy of hot dip galvanized coatings on typical structural members averages far in excess of 50 years in most rural environments and even in severe urban and coastal exposure.
Strongest Coating
The unique metallurgical structure of hot dip galvanized coating gives outstanding resistance to mechanical damage in transport, erection and service.
Comprehensive Protection
Every part of a hot dip galvanized structure is protected, including recesses, sharp corners and inaccessible areas. No other coating can provide such comprehensive protection.
Speedy Construction
Hot dip galvanized steel is ready for final installation upon delivery. There is no need for on-site surface preparation, painting and inspection. This saves substantial construction time and money.
Lowest long-term cost
As hot dip galvanizing provides longer life protection and requires little maintenance for steel, it achieves the lowest long-term cost by eliminating the need for periodic plant shutdown and production disruption.
Guaranteed Reliability
Hot dip galvanizing is carried out to strict international standards, where specific coating thickness is applied to achieve reliable coating life and performance.
Automatic Protection
Hot dip galvanized coatings corrode preferentially to steel via its sacrificial protection to small areas of exposed steel.
Ease of Inspection
It is very easy to inspect the state of hot dip galvanized coatings - simply via visual observation or non-destructive thickness testing methods.
Independent of Weather.
A four-coat paint system requires a week to complete. The hot dip galvanizing process is not dependent on weather conditions and every hot dip galvanized structure is ready-for-use.
The Facilities
UNIK's kettle capacity measures at 12.5m in length, 1.3m in width, and 2m in depth.
At UNIK, Special High Grade (SHG) Zinc is used for the Hot Dip Galvanizing process, where the purity level is at 99.995%.
