Looking for base materials for glass processing and home decoration windows and doors? Float glass offers both excellent cost-effectiveness and superior quality! We recommend “low-iron float glass” as your top choice—its iron content is ≤0.015%, and its light transmittance is ≥91%. Compared to ordinary float glass, it’s more transparent and free from any greenish tint. For home decoration windows and doors, use 4–6mm float glass; after tempering, its impact resistance doubles!

For glass processing (coating, laminating, and engraving), select 8-12mm float glass with high flatness (tolerance ≤ 0.3 mm/m) for more stable results after processing.

For custom aquariums, choose ultra-clear float glass—bubble-free and scratch-free—for clearer views of your fish. When purchasing, be sure to check: the surface is free of ripples and impurities, and the edges are free of burrs.
