HOT-DIP GALVANIZING PLANT
We provide galvanization services of all kinds of iron articles which include angles, channel, flat, round, pipe scaffolding parts and various other fabricated parts
ABOUT
Steel is the prime material used in modern construction and has been since the beginning of the industrial revolution. Engineers, architects and construction professionals trust the strength and durability steel provides; however, as soon as steel is exposed to the environment, it begins to corrode.
Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. These inter-metallic layers are harder than the base steel itself, resulting in an extremely abrasion resistant coating that can last for decades.
We at Delta Galvanizers, have expert staff who can provide advice about fabrication and design for galvanised items, and work to provide the highest quality strength and finish while they are being serviced. Our equipment ensures we can help with any project, no matter how big or how small. We work with you to meet your needs.
INFTRASTUCTURE
Surface Preperation
With tanks for de-greasing with Caustic solution, Pickling with HCl and Fluxing we provide the best possible surface preparation for a better finish of the galvanized surface.
Galvanization
After fluxing, the material is put on a dryer. With the Zinc bath of 7m, we are able to galvanize a wide variety of products angles, channels, flat, scaffolding items and other fabricated items etc.
Finishing & Inspection
The galvanized material is quenched in chromate water for a better finish. The material is then checked with a Digital Coating Thickness Tester to ensure the best quality.
PROCESS
Degreasing
A hot alkaline or caustic solution removes dirt, oil, grease and soluble markings.
Pickling
A dilute solution of hydrochloric acid removes surface rust and mill scale to provide a chemically clean metallic surface which is required for galvanization.
Fluxing
Through the final surface preparation step, any remaining oxides are removed in a zinc ammonium chloride solution and a protective layer is deposited on the steel to prevent any further oxides from forming prior to galvanizing.
Galvanizing
Following surface preparation, the steel will be immersed in a bath of molten zinc. The zinc kettle contains at least 98% pure zinc and is maintained at a temperature between 815º-850º F (435º-455º C). While steel is immersed in the kettle, the zinc reacts with the iron in the steel to form a series of metallurgically bonded zinc-iron alloy layers with the final top layer 100% zinc.
Inspection
The inspection process of galvanized steel is fairly simple. Zinc will not react with unclean steel, therefore a visual inspection of the product will provide a good assessments of the quality of the coating. Coating thickness and surface condition inspections complete the process to ensure compliance with specification. Electronic gauges are used to give quick and accurate measurement readings of the coating.
