Sandpaper is a material used in the process of smoothing and polishing metals. It can completely remove even the smallest scratches, enhance the product’s aesthetics, and meet the strict requirements of the market.
Sandpaper and its classifications
Sandpaper is one of the abrasive materials categorized based on its grit size. Specifically, sandpaper is classified according to the coarseness or fineness of its surface as follows:
- Coarse-grit sandpaper: P40, P60, P80, P100, P120
- Medium-grit sandpaper: P150, P180, P220, P240, P320, P400, P500, P600, P800
Fine-grit sandpaper: P1000, P1200, P1500, P2000, P2500 - Ultra-fine-grit sandpaper: P3000, P4000, P5000, P6000, P7000, P8000
Sandpaper classification by surface grit level
Classification of sandpaper by fineness
With grit sizes starting from P1000 and above, fine sandpaper is used during the final stages of finishing, providing the ultimate polishing for materials such as wood and metal. Additionally, the higher the grit size, the more suitable the sandpaper is for applications requiring a highly smooth and glossy surface finish.
Characteristics of Sandpaper
Unlike low-grit sandpaper that can leave scratches and reduce the aesthetic and quality of a product, fine sandpaper completely overcomes these drawbacks. In addition, it has the following characteristics:
- Soft, flexible, and highly durable properties
- Wide range of abrasive grits with high fineness: P1000, P1500, P2000, P2500, P3000
- With its simple structure and composition, fine sandpaper is highly effective for finishing surfaces that require a high-gloss finish.
- Can be used for wet sanding, dry sanding, or a combination of both
- The foam layer in the middle helps minimize risks caused by hand pressure during sanding makes the sanding process simpler, faster, and easier
