Half armored glass is situated between between the ordinary plate glass and an armored glass variety, it has at the same time the armored glass the partial merits, like the intensity is higher than the simple glass, simultaneously avoided the armored glass smoothness to be bad, Yi Zibao, once the destruction was the whole smashing and so on the unsatisfactory weakness.

Half armored glass superficial compressed stress in 24MPa to 52MPa between, the armored glass surface pressure should be bigger than 69MPa.
Half armored glass production process and the armored glass is same, only has the difference in the quenched location wind pressure, cooling can be smaller than the armored glass.
