1 Ultra-high light transmittance Light transmission reaches 91%–92% (6mm), much higher than standard clear float glass (around 86–88%). Brighter and cleaner visual effect.
2 Almost no green tint, water-white appearance Low iron content eliminates the green edge colour of ordinary glass. The glass edge looks transparent and colourless, ideal for visible-edge designs such as stair treads and frameless railings.
3.True colour rendering It will not distort the colour of objects behind or beneath the glass. Suitable for museum showcases, retail display cabinets and printed laminated glass.
4.Flexible deep processing Available for tempering, laminating, hot bending, silk printing, frosting, LowE coating, hole drilling, notching and edge polishing.
5.Stable physical performance Retains all basic float glass properties. After tempering, it becomes safety glass with high impact and thermal shock resistance.
6.Wide application compatibility Works for both exterior facade and interior decorative scenarios, matching modern minimalist, luxury and thirdspace design styles.
Q1 What is the difference between low iron glass and normal clear float glass?
A1 Ordinary clear glass contains more iron oxide, which creates a visible green hue, especially noticeable on thick glass edges. Low iron glass has iron content ≤0.015%, showing a water-white colour. It has higher light transmission and restores the true colour of objects behind the glass, but it is more costly.
Q2 What is the light transmittance of low iron glass?
A2 For 6mm low iron glass, light transmittance can reach ≥91%, while standard clear float glass is only around 86%–88%. Thicker low iron glass still maintains much better clarity than regular glass.
Q3 Can low iron glass be tempered, laminated or hot bent?
A3 Yes. Low iron glass supports all deep processing: tempering, laminating with PVB/SGP/EVA film, hot bending into curved shape, silk printing, frosting and LowE coating. It can be made into low iron tempered laminated glass and curved low iron laminated glass for high-end construction.
Q4 When should I choose low iron glass instead of regular clear glass?
A4 Choose low iron glass when the glass edge is exposed, or accurate colour presentation is required. Typical cases: frameless balustrades, stair glass treads, skylights, canopies, museum display cabinets, glass furniture and luxury interior partitions.
Q5 Is low iron glass stronger than ordinary glass?
A5 No. The base low iron float glass has the same mechanical strength as regular float glass. It becomes safety glass only after tempering treatment.
