Pre-coated sheets are sheets that have already been coated with a layer of material, such as paint or a protective coating, before being used in a construction project. This coating helps to protect the sheet from corrosion, weathering, and other damage.

Granulated sheets, on the other hand, are sheets that have a textured surface made up of small granules or particles. These granules can provide additional traction and grip, making them ideal for use in roofing or flooring applications where slip resistance is important.

In summary, pre-coated sheets have a protective coating applied before use, while granulated sheets have a textured surface made up of small granules for added grip and traction.

Pre-Coated Sheets

- Process: Metal sheets are coated with a layer of paint, plastic, or other protective material before being formed into final products.
- Coating: The coating is applied using techniques such as roll coating or spray painting.
- Thickness: The coating is typically thin, ranging from a few microns to several hundred microns.
- Purpose: Pre-coated sheets provide corrosion protection, aesthetic appeal, and durability. They are used in applications such as roofing, siding, and appliances.
- Advantages:
- Consistent and uniform coating
- Excellent corrosion resistance
- Wide range of colors and finishes
- Improved durability and lifespan
- Cost-effective for mass production

Granulated Sheets

- Process: Metal sheets are coated with a layer of granulated material, such as stone chips or ceramic particles.
- Coating: The coating is applied by sprinkling or embedding the granules into a liquid adhesive.
- Thickness: The coating is typically thicker than pre-coated sheets, ranging from several millimeters to several centimeters.
- Purpose: Granulated sheets provide texture, skid resistance, and UV protection. They are used in applications such as flooring, countertops, and exterior walls.
- Advantages:
- High durability and abrasion resistance
- Non-skid surface for safety
- Good insulating properties
- Aesthetically pleasing with a variety of textures and colors
- Suitable for both indoor and outdoor use

Key Differences

- Coating material: Pre-coated sheets have a thin, smooth coating, while granulated sheets have a thick, textured coating.
- Coating process: Pre-coated sheets are coated before forming, while granulated sheets are coated after forming.
- Purpose: Pre-coated sheets provide protection and aesthetics, while granulated sheets provide texture, durability, and insulation.
- Applications: Pre-coated sheets are common in roofing, siding, and appliances, while granulated sheets are used in flooring, countertops, and exterior walls.
- Cost: Pre-coated sheets are typically more cost-effective for mass production, while granulated sheets may be more expensive due to their thicker coating.
