High-transparency float glass with reduced iron content for enhanced clarity, brightness
Low-iron float glass, also known as ultra-clear float glass, is a high-transparency float glass with very low iron content(less than 150PPM). This results in superior clarity, higher light transmittance. It is ideal for high-end architectural facades, display windows, solar energy systems, and decorative applications where visual appearance is critical. Low-iron float glass supports advanced processing such as tempering, laminating, printing, and coating. Its exceptional optical purity and aesthetic appeal make it a preferred material for premium projects that demand maximum transparency and refined visual impact.
