There are two types of metal sheets used in construction, the Galvanized Iron or G.I. and the Black Iron (B.I.) Sheet. The G.I. Sheet is a metal sheet coated with protective metallic and organic coatings that prevents rust. This is commonly used in automotive, wind, and solar industries. While the B.I. Sheet is made up of copper and aluminum. It is commonly used as a material for gate, and gutter fabrication.
TKL offers G.I. and B.I. Sheets in various gauge or thickness in 4 by 8 feet size with ready stocks available. We also accept 6 x 20 feet orders.
G.I. Sheet (mm) – #26, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.8, 2.0, 2.2

Uses of G.I. and B.I. Sheets
G.I. and B.I. Sheets have various uses in the construction sector. Here are some of the common applications.
- Door and wall panels
G.I. Sheets are used in fabricating door and wall panels due to its flat surface.
G.I. Sheets have protective coating that make it an ideal material for roofing.
3. Home appliances
G.I. Sheets are also commonly used in home appliances as it is lightweight and can last for a long time.
- Air condition and refrigeration systems
B.I. Sheets are used in cooling systems as it is lightweight and quite resistant to corrosion.
B.I. Sheets are used in the automotive industry as flooring due to its thickness and sturdiness.
3. Outdoor billboards
B.I. Sheets are used for outdoor billboards due to their aesthetic qualities.
Advantages of using G.I. and B.I. Sheets
G.I. and B.I. Sheets are commonly used in various construction projects due to the following benefits:
G.I. & B.I. sheets are malleable as it can be designed into a new shape without breaking.
The lifespan of G.I. & B.I. sheets can last up to 50 years or more depending on how you clean or maintain it.
Compared to other construction materials, G.I. & B.I. sheets have a low cost making it an ideal material to use in construction if you have a limited budget.
4. Faster construction time
Since G.I. & B.I. sheets are ready to use, you can easily assemble and prepare it to use for construction.
