Garnet is the preferred abrasive for stainless steel blasting due to its low free‑iron content, which prevents surface contamination and post‑blast corrosion. Unlike steel grit or aluminum oxide, garnet creates a consistent anchor profile without over‑cutting or warping thin materials. It also generates less respirable dust, improving workplace safety and cost predictability. Typical applications include thin‑gauge tanks, food and pharmaceutical equipment, sanitary piping, and architectural finishes. Always test on scrap material first; 20/40 or 30/60 mesh garnet is generally recommended. SEPPE offers free samples for validation. Read More

Many customers reuse garnet abrasives to save costs. But how many times can you recycle it? And when should you stop? Using worn-out garnet doesn’t just slow down your work—it can also harm your equipment and your health. Here’s what you need to know. Typical Reuse CyclesFor most standard blasting a Read More

Garnet sandblasting is widely used for metal surface cleaning and preparation. For most projects, the next step after blasting is coating—paint, lining, or anti-corrosion layers.But there is a hidden risk: soluble salts like chlorides left on the surface after blasting absorb moisture, penetrate the Read More

SEPPE Garnet has become the preferred abrasive for sandblasting, and for good reason. It combines high performance with genuine cost-effectiveness. Here are the key advantages: Lower consumption, longer use Its hardness and durability allow for multiple reuses (up to five cycles), while cheaper abra Read More

Industry data shows that up to 80% of coating failures result from inadequate surface preparation. Often, the root cause is the wrong choice of abrasive.Low-purity abrasives such as copper slag or coal slag contain residual heavy metals, high levels of soluble salts, and irregular particle shapes.

SEPPE introduces its 80 mesh garnet for waterjet cutting. Produced from high-purity material with precise sizing, each batch is QC-tested to minimize dust and remove ineffective grains—delivering consistent cutting efficiency.Garnet has become the preferred abrasive for waterjet cutting due to its u Read More

As we all know, garnet is a natural mineral abrasive. And it is widely used in water cutting, sandblasting, and water filtration.Garnet has multiple sources, of which three are known: garnet deposits, beaches, and river channels. Due to their different sources, the hardness, purity, color, and impur Read More

When it comes to cutting materials with extreme precision and without heat, waterjet cutting is the technology of choice. And at the heart of this powerful process is a natural mineral: garnet abrasive. Read More

Natural river sand garnet is extracted from natural river channels, and its yield may vary due to seasonal factors. Due to our factory being located in a region close to raw materials in northern China, the weather often drops very quickly starting from October. Ice will start to freeze from Novemb Read More

Garnet abrasives are widely used in blasting operations due to their hardness, efficiency, and reusability. However, the presence of moisture or conductive impurities can affect both performance and safety which will reduce the lifetime of coatings.Electrical conductivity testing according to ASTM D Read More
