All grades: soda-lime borosilicate glass · white free-flowing powder · ISO 9001/14001/45001 plant · COA with density, crush strength, PSD and moisture per lot · retained samples 5 years. Custom size cuts, surface treatments and packaging (500 kg big-bag / 20 kg carton / moisture-barrier drum) on request.
Same borosilicate chemistry and flame-forming process lineage; crush-strength retention certified per lot against the same ASTM/ISO test methods the majors use.
Single-site 30,000 t/yr capacity with 50+ standard grades — no multi-plant batch drift, one QC system, one COA format worldwide.
Landed economics typically 30–50% below legacy grades at equal crush rating, before distributor margin stacking. DDP, CIF and FOB terms supported.
Expansion to 100,000 t/yr under construction. Campaign volumes for cementing, explosives and coatings secured by contract, not spot availability.
