HL and NO.4 is a product that generates grinding patterns through continuous grinding of polishing sand belts with appropriate particle size (sub division 150-320). Mainly used for building decoration, elevators, doors, panels, etc.

Metal wire drawing is a common decorative method in daily life. It can be manufactured into several types, including straight lines, threads, ripples, random lines, and spiral lines. This surface treatment has the characteristics of good hand feel, fine luster, and strong wear resistance. It is widely used in electronic devices, home appliances, mechanical equipment, and other fields.

Coarse sand NO.3: The product is ground using a 100-120 grinding belt. Has good glossiness and discontinuous coarse lines. Used for interior and exterior decoration materials, electrical products, and kitchen equipment in buildings.

Fine sand NO.4: a product obtained by grinding with a grit size of 150-180 grinding tape. It has better glossiness, discontinuous coarse lines, and finer stripes than NO.3. Used for bathrooms, interior and exterior decoration materials, electrical products, kitchen equipment, and food equipment.

#320 is a product produced by grinding with a 320 grit grinding tape. It has better glossiness, discontinuous coarse lines, and finer stripes than NO.4. Used for bathrooms, interior and exterior decoration materials, electrical products, kitchen equipment, and food equipment.
