Hat thuy tinh: thong so ky thuat va tieu chuan
Linghang produces solid glass beads and glass microspheres from 20 to 500 mesh at our factory in Yongqing County, Hebei. Every grade is characterised by refractive index (R.I.), retroreflectivity (RL), particle size distribution and roundness — the four parameters that determine how a bead performs in road marking, grinding, blasting and composites.

| AASHTO M247 | USA | Drop-on & premix beads for pavement markings: gradation, R.I., roundness, moisture resistance. |
| EN 1423 / EN 1424 | EU | Type 1 / Type 2 drop-on materials and premix glass beads; R.I. and grading requirements. |
| BS 6088 | UK | Glass beads for road marking: particle size distribution, refractive index, chemical resistance. |
| GB/T 24722-2020 | China | Pavement marking glass beads: No.1-4 bead uses, R.I. classes, roundness, magnetic particles, heavy metals. |
| GB/T 16311-2024 | China | Road marking quality & test methods: 4 retroreflectivity classes (I-IV), 48h-30d initial reading window, skid resistance BPN. |
| ASTM D4280 / D1107 | USA | Premix and drop-on beads: sieve analysis, R.I. determination methods. |
| ISO 9001 | International | Quality management system covering raw glass selection, melting, grading and batch QC. |
Beads for road marking are graded by refractive index: R.I. 1.50 for standard drop-on and premix applications, 1.70–1.90 for high-brightness markings, and above 1.90 for premium wet-night-visibility systems. Roundness matters as much as clarity: under GB/T 24722-2020, No.1 and No.2 beads require at least 80% roundness, and defect beads at medium/high refractive index are capped at 20%.

- Raw material control: recycled and virgin glass cullet is inspected for colour, iron content and contamination before melting — iron and opaque particles are the main cause of low retroreflectivity.
- Batch-testable: R.I., RL and particle size distribution are checked per batch, and a test report can accompany each shipment on request.
- Custom grading: non-standard mesh windows and blended gradations can be produced to your coating or blasting specification.
- Export packing: 25 kg bags, 500 kg / 1000 kg jumbo bags, or 25 kg cartons on pallets; container loading plans provided before shipment.
If you are evaluating a supplier, the fastest test is a sample marking: we ship samples so you can check roundness under a microscope, run a sieve analysis, and measure RL on a trial stripe with your own paint. Tell us your mesh window, application and target market, and we will confirm the grade, MOQ and FOB price.
