PRE-GALVANIZED STEEL PIPE
* Process: Pre-galvanized steel pipes are galvanized before they are formed into the final product. The galvanization process
typically involves coating the steel with a layer of zinc through either a hot-dip process or an electroplating process.
* Appearance: Pre-galvanized pipes have a smoother and more even zinc coating. The surface is usually shinier and has a uniform
appearance.
* Application: Pre-galvanized pipes are often used in applications where the final appearance is important, such as in outdoor
structures, fencing, and decorative applications.

HOT DIP GALVANIZED STEEL ROUND PIPE
* Process: Hot-dip galvanized steel pipes are formed first and then immersed in a molten bath of zinc. The immersion process results in a thicker and more durable zinc coating compared to pre-galvanized pipes.
* Appearance: Hot-dip galvanized pipes may have a rougher surface compared to pre-galvanized pipes due to the thicker zinc coating. The coating is usually more uneven, but it provides greater protection against corrosion.
* Application: Hot-dip galvanized pipes are commonly used in applications where corrosion resistance is a critical factor, such as in water pipelines, construction, and outdoor structures exposed to harsh environments.

Different Surfaces
Normal spangle
Through addition of certain heavy metal element into molten zinc bath, regular spangle pattern is produced on Hot-dip zinc-coated steel sheet.
Minimized spangle
The zinc layer(coating) does Not contain Lead(Pb), which complies with EU WEEE and RoHS directives. This is a non-toxic and environmental friendly material.
Spangle-free
During hot-dip galvanizing, only a certain amount of aluminum is added to the zinc solution, and lead-free, antimony, and tin are not added to produce spangle-free products.

Main Features of Galvanized Steel

Anticorrosive: 13 years in heavy industrial areas, 50 years in the ocean, 104 years in the suburbs and 30 years in cities.
Cheap: The cost of hot-dip galvanizing is lower than that of other coatings.
Reliable: The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more
durable.
Strong toughness: The galvanized steel sheet layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
Comprehensive protection: Every part of the plated piece can be galvanized, and is fully protected even in depressions,sharp corners,and hidden places.
Save time and energy: Galvanizing process is faster than other coating methods.
