1, What is low iron tempered glass?
In different area or countries, low iron glass is also called ultra clear glass or extra clear glass or optic white glass.
Low iron tempered glass is also referred as fully tempered low iron glass.
It is processed by using low iron glass cut to size, later the low iron glass will be grinded by edging machines, after the edging process, the low iron glass will be transferred to tempering furnace, heating up to over 600 degrees temperatures and later cooled down rapidly by strong wind jet. Therefore will form a high compression on the low iron tempered glass whereas still tension interior.
Low iron tempered glass has over 5 times strength higher than normal low iron float glass, with tempering stress over 90Mpa, can endure strong impact without breaking, even when broken due to extremely high impact, the tempered glass will shatter into small pieces with obtuse angles which will do no harm to humans.
Comparing to clear glass or other tinted glass, low iron glass is purer, has a better appearance. More importantly, it has a very low risk of tempered glass spontaneous breakage. If combine with the heat soak test process, the 19mm low iron tempered glass will have almost zero spontaneous breakage rate.
Therefore it is super suitable for large sizes glass projects such as lobby glass wall or facade fins glass, etc. Shenzhen Dragon Glass as one of the best low iron tempered glass suppliers in China can help provide you the best solutions for tempered glass products.
