Product Overview

Balanced Flexibility, Cutting Performance and Durability

Our sandpaper sheets are converted from jumbo sandpaper rolls and designed to balance cutting performance, flexibility, and durability.
By optimizing abrasive grain, paper backing, and coating density, the sheets resist cracking during hand sanding and tearing during machine-assisted use, making them suitable for multiple working conditions.

Abrasive Grain Selection by Material

Ensuring Efficient Cutting and Surface Consistency

Aluminum Oxide
Suitable for wood, general metals, and standard sanding applications with stable cutting performance.

Silicon Carbide
Ideal for fine sanding, stainless steel, and coating preparation where a smooth surface finish is required.

Hand Sanding vs. Machine-Assisted Use

Choosing the Right Configuration for Each Working Method

Hand Sanding Applications

For hand sanding, sandpaper sheets should offer flexibility and crack resistance to conform to workpiece surfaces.

• Recommended backing: C / D weight paper
• Recommended grit range: P120 – P400
• Advantages: Better control for detail work and edge finishing

Machine-Assisted Applications

For machine-assisted sanding, sheets require higher tear resistance and dimensional stability to withstand continuous motion.

• Recommended backing: D / E weight paper
• Recommended grit range: P60 – P240
• Advantages: Higher material removal efficiency for large surface areas

Grit Selection by Sanding Stage

From Rough Shaping to Fine Finishing

• P40 – P80: Coarse sanding and rapid stock removal
• P100 – P180: Medium sanding and surface leveling
• P220 – P400: Fine sanding and coating preparation
• Above P600: Fine finishing and surface improvement
