Road glass beads for parking lot marking are spherical micro glass particles added into parking marking paint to form retroreflective lines, widely used for commercial parking, underground garage and industrial parking marking. This article introduces bead function and procurement selection tips for overseas property contractors and coating raw material buyers.
Parking lot grade road glass beads have three core features. Optical parameters guarantee stable reflection for daily vehicle lighting. Mature melting and screening technology controls particle shape. Good compatibility with ordinary cold or hot marking paint. It is necessary to select beads matching coating formula and vehicle traffic volume.
Frequent procurement errors. Buy high-grade beads for small parking projects, bring extra cost, evaluate traffic load before ordering. Judge bead quality by transparency, transparent beads may have low roundness, request lab data. Ignore sea freight moisture risk, beads agglomerate and affect construction, use waterproof sealed bags. Accept bulk cargo without sampling inspection, inconsistent batch quality may cause rework, arrange pre-shipment test. Select suppliers without custom particle size service, cannot fit special paint formula, confirm custom processing.
Four application scenarios. Outdoor parking hot melt marking: drop-on road glass beads. Underground garage cold paint marking: premix medium refractive beads. Light traffic community parking: economical standard beads. Large commercial parking heavy traffic: high strength reflective beads.
