What is pre-galvanized GI Steel?

GI steel, pre-galvanized steel, or cold-rolled steel is produced through the coil galvanization process. By first slitting GI coils into different sizes depending on the types of pipe, which then it will be shaped and manufactured into many different objects, such as pipes, tubes, and light lip channels. This type of steel is commonly used in welding works as it does not require rust-resistant painting and saves time. It is also suitable for roof constructions due to its lightweight and durability. Its corrosion resistance makes it a good alternative choice to regular steel pipe and is well-received in the construction industry.

How is GI steel differ from GA steel?

GI steel is TIS 50-2561 manufactured, resulting in shiny and clean appearance. GA steel is not processed under TIS, and the galvanization of GA depends on its usage. The dull surface of GA steel makes it easier to paint on

What is the difference between galvanized steel pipe and GI steel pipe?

Galvanized steel pipes are zinc-coated steel pipes, come with or without thread, and are suitable for water pipeline constructions. GI steel pipes are produced by the coil galvanization process and are shaped into a pipe form, which is ideal for constructions that do not require heavy loads. It cannot be used in water-related constructions.

What is weld cleaning?

Seams are the welded joint outline that develops during the shaping process. The manufactures usually weld and clean the seams to improve durability and give the steel rust-resistant properties. Then, they clean the surface with weld spraying.

What is OD (Outside Diameter)?

OD is the outside diameter of steel pipes or C pipes that each factory produces with similar manufacturing sizes, such as 23 mm x 23 mm, 24 mm x 24 mm, and 25 mm x 25 mm. The differences in OD affect the weight of each steel pipe. For example, 1.10 mm thickness with 23 mm x 23 mm OD results in approximately 4.5kg./bar. While with OD of 25 mm x 25 mm, the weight will be 5.00kg./bar.

What is "white rust" and how to handle it?

White rust develops when a chemical reaction occurs due to the steel being exposed to humidity. Steel should be stored indoors or in a storage with ventilated conditions. It should be protected from any humidity to avoid white rust issues.
