The degree of steel is divided into 3 kinds;
⒈ tempered glass: steel degree = 2 ~ 4N / cm, glass curtain wall tempered glass surface stress α ≥ 95Mpa;
⒉ semi-tempered glass: steel degree = 2N / cm, glass curtain wall semi-tempered glass surface stress 24Mpa ≤ α ≤ 69Mpa;
⒊ super fortified glass: degree of steel> 4N / cm.
?? Tempered glass is produced monolithic, but can be processed into laminated glass, insulating glass and other multi-layer composite glass. Relative to the composite glass, direct monolithic use, is the monolithic tempered glass.
