Import Aluminum Coated Glass Bead — Buy in wholesale FOB from Supplier in China

Aluminum coated glass beads from Jinan Huaming Microbead Material Co., Ltd. consist of spherical glass microbeads with a hemispherical aluminum coating, manufactured to a refractive index of 1.93 +/- 0.01 Nd. The base glass composition follows the TiO2-BaO-SiO2 system, yielding a specific gravity of 4.1 +/- 0.2 g/cm3. Supplied in five standard sieve fractions from 10-25 um up to 75-90 um, these silver-grey fine spheres deliver hassle-free handling across reflective applications where precise particle size distribution controls optical performance.

The semi-coated aluminum layer creates a retro-reflective interface where light entering the glass sphere reflects back toward its source, a principle governed by the refractive index and coating geometry. Grade I material achieves retro-reflective coefficients of 50-100, while Grade H reaches 65-130, the higher bracket suiting premium safety applications. The BaO-TiO2-SiO2 glass matrix offers chemical stability against road salts, UV degradation, and moisture, typical characteristics for traffic-grade reflective beads. Standard packaging for industrial glass beads is 25 kg paper or plastic bags on pallets, though buyers should confirm Jinan Huaming's exact configuration.

Primary buyers include road marking material formulators, reflective ink manufacturers, and traffic safety equipment producers. These beads blend into solvent-based and UV-curable inks for screen printing high-visibility signage on textiles, labels, and road cones. The 20-40 um and 40-55um fractions suit fine-detail printing, while 65-75 um and 75-90 um grades embed effectively into thermoplastic road marking compounds. Import buyers should verify the supplier's current production capacity, lead times from Shandong, and whether technical datasheets include batch-specific retro-reflectivity test results.

Jinan Huaming Microbead Material Co., Ltd. operates from 12 Mao Ling Shan Road in Jinan, Shandong Province, a region with established glass and ceramic manufacturing infrastructure. The supplier holds an imported tier designation with harbor trust status, indicating platform-level verification rather than third-party audit. The response rate shows 0.00% with zero average response hours recorded, so direct communication channels should be tested before committing to orders. No employee count, revenue figures, or factory floor details are present in the profile.

The listing focuses narrowly on aluminum coated glass bead specifications without claiming ISO certification, patent holdings, or client references. Buyers should treat this as a specialized materials supplier with a single-product emphasis, which can indicate focused manufacturing competence or limited operational scope. Verification of production consistency, quality control batch testing, and export documentation capability should precede any trial order. The Shandong location offers access to Qingdao port for sea freight, a logistical factor worth confirming for container load planning.
