Rust causes the corrosive metal to change the color and if one may object rust for a long time, there is a gradual deformation in shape. There are many ways to prevent rust. Hot-dip galvanizing is one such option that is often used for industrial purposes.
Electroplating is a process where zinc, non-corrosive, corrosive to metals such as iron and steel coated. Because zinc is more reactive than iron or steel, which corrodes first galvanized coating, protecting the steel or iron substrate. Hot-dip galvanizing is a form of ‘steel pipe galvanization’ (Also known as ‘ท่อเหล็กชุบสังกะสี’ in the Thai language)’.
Hot Dip Galvanized Steel, Hot-dip galvanizing is to bond with steel zinc at the molecular level. This allows the coat to the entire surface, including scratches, holes, joints and even coverage.
The first three layers are used, zinc-iron alloy and the fourth is pure zinc. Zinc-iron alloy increases the strength of steel, while the last layer of pure stainless steel prevents corrosion.
Appearance dull silver galvanized surface polished to gray depending on factors such as the composition of the steel, the rate of withdrawal of molten zinc bath and the cooling method used will vary.
Galvanized steel is widely used in applications where corrosion resistance is required, such as roofs and facades, balustrades, consumer electronics devices and automotive body parts used. They can be identified by the crystallization patterns on the surface, known as spangle.
Galvanized steel sheets are often used in automotive, to improve the corrosion resistance of the body parts. Galvanized steel is used in pipes, sheets, rods, and wire, among others – street pole.
Galvanized pipe, it is the entire pipeline system. Although this may be costly and unnecessary, it is actually much more affordable to replace the pipes, such as for repair and the high cost of salaries with the broken pipe live so long.
Galvanized sheets offer many cost savings to consumers. The process of the hot-dipped sheet does not require a lot of work as some other coating process, helping to keep costs down.
