When purchasing a PPGI coil in Jinja, Uganda, for your project, ensure you have a keen understanding and make an informed decision. Let’s start with the blog to know precise details about galvanized coils.
What is a PPGI Coil?
PPGI coil stands for Pre-Painted Galvanized Iron coil. Furthermore, it is a type of steel sheet or strip that has been coated with a thin zinc layer and painted in a factory before forming, thereby preventing corrosion. However, this precise procedure secures the steel from corrosion and delivers a sleek finished look, making it a reliable and suitable choice for appliances, residential, construction, and other domains.
Additionally, the zinc coating acts as a robust barrier between the steel and its surroundings. Likewise, it is one of the best ways to prevent rust and corrosion from forming on the steel’s external surface. Moreover, it serves as a robust layer that stands when the external coating is scratched or damaged, and the zinc oxidizes before the inner steel. Therefore, galvanized coil in Kampala, Uganda, is often produced from 0.2% low-carbon content steel. Nevertheless, this steel is selected for its ease of workability, exceptional formability, and weldability.

What are the Significant Types of PPGI Steel Coil?
Here, we have listed the key types of PPGI steel coil, which have numerous uses across different industries. Let’s check them out one by one.
1. Hot-Rolled Steel Coil (HRC)
A hot-rolled GI coil in Mbarara, Uganda, is a type of steel product made by heating steel slabs above their recrystallization temperature, then rolling them into a straight strip, which is coiled for seamless storage and transport. Furthermore, this procedure makes steel shaping easier due to its malleability, resulting in a rougher external surface finish and black residue known as mill scale. Likewise, hot-rolled steel offers strong, durable, and cost-effective properties, making it a primary choice for applications across different industries. Additionally, precise dimensions are not essential for hot-rolled steel coils.
Technical Configuration of Hot-Rolled Steel Coil (HRC)
| Parameter | Typical Specification |
|---|---|
| Product | Hot Rolled Steel Coil (HRC) |
| Standards | ASTM A36, ASTM A1011, JIS G3101 (SS400), EN 10025 |
| Thickness Range | 1.2 mm to 25 mm |
| Width Range | 600 mm to 2050 mm |
| Coil Weight | 5 to 35 metric tons |
| Coil ID | 508 mm / 610 mm |
| Surface Finish | Black, mill scale |
| Edge Condition | Mill edge or trimmed edge |
| Tensile Strength | 370 to 540 MPa |
| Yield Strength | 235 to 355 MPa |
| Elongation | 20 to 30 percent |
| Tolerance (Thickness) | ±0.10 to ±0.50 mm |
| Tolerance (Width) | ±2 to ±10 mm |
| Applications | Structural, fabrication, pipe, automotive, shipbuilding |

2. Electro-Galvanized Steel Coils
When producing an electro-galvanized steel coil, the PPGI coil supplier in Entebbe, Uganda coated the electro-galvanized steel coil with a uniform, thin layer of zinc by an electrolytic process to protect against corrosion. Nevertheless, this electrocoating results in a smoother, more aesthetically pleasing, and brighter finish than hot-dipped galvanized steel. Therefore, it makes it an ideal choice for indoor applications, such as appliances, electronics, and automotive interiors.
