Visual Comparison between Low-Iron Glass and Common Glass

Low Iron Glass

The low iron glass is also called ultra clear glass. Common float glass looks green to certain degree. Especially when the glass is thickened or piled together, such phenomenon is more obvious. However, the architectural designers sometimes require clearer glass, so the low iron glass emerges. This material has high light transmittance and its perfect transparency enables you to obtain more perfect visual effect of natural color.

Size Scope
Max. Size: 2440mm×3660mm
Min. Size: 300mm×300mm
Thickness: 3mm-22mm

Application
The low iron glass is widely used to make a lot of objects, such as the show case of museum, counter of gold shop, point-supporting curtain wall, door, window, and furniture. It is also applied in the botanical garden, greenhouse, aquarium, shower room, large theatre, and hotel hall.
