Shahe Shott Glass Co., Ltd. has manufactured high-performance coated glass beads since 1996, supplying automotive, aerospace, electronics, and industrial finishing markets with products that meet ASTM D1155, SAE J441, and ISO 9001:2015 standards. Our 3 modern plants (20,000 sqm total) and 24/7 production lines enable us to deliver consistent quality at scale, with OEM/ODM design capabilities and short lead times.
We don’t just sell glass beads—we engineer solutions that reduce your abrasive consumption by up to 40%, cut processing time, and extend nozzle life by 30%. With FCC, CE, RoHS, and FDA certifications, we ensure your coated glass beads comply with North American, European, and Asian regulations without delays.
Industry Pain Points We Solve
- 🔴 Inconsistent bead quality → causes irregular surface finishes and waste in sandblasting/shot peening.
- 🟡 Slow delivery from Europe/US suppliers → project delays and lost contracts due to extended lead times.
- 🔵 High abrasive consumption → raises per-unit costs by 25% and increases environmental impact.
- 🟢 Regulatory non-compliance risks → shipment holds at customs due to missing CE/FCC/RoHS certificates.
- 🟣 Limited customization options → forces buyers to compromise on performance or pay premiums for specialty coatings.
Sound familiar? 92% of our clients report a 30%+ reduction in abrasive replacement frequency after switching to our coated glass beads. Here’s how we deliver.
