Trizact Sanding Disc Supplier | Pyramid Foam Sanding Disc Manufacturer
Consistent Finish. Controlled Cutting. Reduced Rework.
Aozhong’s foam-backed grinding discs feature pyramid-shaped abrasives (Trizact type) and are specifically designed for high-precision finishing, where consistency, uniform scratch patterns, and process stability are critical.
Featuring a black microstructured abrasive surface, an elastic foam core, and a color-coded hook-and-loop backing, these discs deliver predictable cutting performance, extended service life, and exceptional pre-polished surface finishes for automotive, metalworking, electronics, and high-value manufacturing applications.
Product Structured
Structured Abrasive Surface (Top Layer)
A specially designed pyramid-shaped abrasive structure arranged in a uniform pattern. Each microstructure contains multiple abrasive particles embedded in resin.
Foam Transition Layer
High-density polyurethane foam used to control pressure, conform to surfaces, and protect edges.
Hook-and-Loop Backing (Bottom Layer)
Color-coded backing for quick installation and easy identification of grit sizes.
Core Technology: Structured Pyramid Abrasives
This product utilizes structured abrasive technology rather than traditional random-coating abrasives.
How It Works?
The abrasive particles are shaped into uniform pyramids or geometric structures.
As the grinding process progresses, the tip of each pyramid gradually wears down.
New, sharp abrasive particles are continuously exposed.

FAQ
What is a structured abrasive sanding disc?
It is a sanding disc with engineered abrasive patterns that provide controlled and consistent sanding performance.
How is it different from standard sanding discs?
Structured abrasives wear evenly, ensuring stable cutting and a more uniform surface finish.
Is it suitable for automotive applications?
Yes, it is widely used for clear coat sanding and polishing preparation.
Does foam backing improve performance?
Yes, it helps the disc conform to surfaces and reduces uneven pressure.
Can you provide customized products?
Yes, OEM and ODM services are available for size, grit, and foam specifications.
