In metal fabrication and surface finishing processes, irregular and complex-shaped workpieces—such as curved components, welded joints, and contoured edges—often face challenges including uneven contact, over-grinding, and inconsistent surface finish.

Conventional coated abrasives, such as sanding discs and belts, rely on relatively rigid backings. When applied to curved or irregular surfaces, they may fail to maintain consistent contact, resulting in uneven material removal and compromised finishing quality. These challenges are particularly critical in applications involving stainless steel, aluminum, and nonferrous metals, where surface integrity and consistency are essential.

According to PDF pages 7–8, non-woven abrasive products are constructed using non-woven nylon fibers combined with aluminum oxide (A/O abrasive). This three-dimensional structure offers distinct advantages over traditional flat abrasive systems:

With a thickness range of 8–9mm and 16mm, the non-woven structure provides cushioning during operation, allowing the abrasive to adapt to surface contours and reduce localized pressure concentration.

Available in Coarse, Medium, Fine, and Super Fine, the grit system supports multi-stage operations—from cleaning and oxidation removal to fine polishing—ensuring smoother transitions across processing steps.

• Flap Discs (75–150mm) for larger surface areas
• Velcro Polishing Pads (2"–7") for localized finishing
• Pads and Rolls for manual or automated processes

These configurations enable compatibility with a wide range of equipment and operational requirements.

Non-woven abrasives are used to smooth weld seams and transition areas, reducing the risk of excessive material removal while maintaining surface uniformity.

Their flexible structure allows for consistent finishing across uneven or contoured surfaces, improving overall surface quality.

Commonly applied in stainless steel and aluminum processing, these abrasives help remove oxidation layers and prepare surfaces for subsequent coating or polishing processes.

• Coarse: oxidation removal and light deburring
• Medium / Fine: surface blending and refinement
• Super Fine: final polishing

• Large curved surfaces: Flap Discs (100–150mm)
• Detailed areas: Velcro Polishing Pads (2"–7")
• Continuous or manual processes: Pads / Rolls

Thicker variants (e.g., 16mm) provide better cushioning, contributing to improved process consistency on complex surfaces.
