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.
