3.2mm Low Iron Patterned Toughened Glass Clear Tempered Solar Glass
Panel
Joy Shing Glass factory directly sells 3.2mm low iron patterned
toughened glass (also known as clear tempered solar glass).
Conventional sizes include: 2251*1128mm, 2272*1128mm, 2378*1297mm,
etc., with high solar transmittance, high mechanical strength, good
impact resistance, anti-aging, low reflection etc. In the field of
photovoltaics, low iron tempered solar glass is mainly used as the
front glass of crystalline silicon modules. Joy Shing Glass
products are of high quality and can meet the industry's 182/210
requirements for the corresponding sizes of different components.
