Customization guide

Adjustable grit parameters (from 40 to 3000) to meet specific surface finishing needs. Custom material blends (e.g., resin-bonded abrasives) can be tailored for chemical resistance or heat tolerance in specialized applications.

Get inspired

With a grit range spanning 40 to 3000, these sanding sheets enable precise surface preparation. Use coarse grits (e.g., P180) to remove imperfections in wood or metal, then transition to finer grits (e.g., P2000) for a mirror-like finish. The high hardness ensures longevity even in demanding industrial workflows.
