Cladding
Our factories are managed by a team of professionals with all the key skills and capabilities required in the design and manufacturing of the curtain wall for both the domestic and export markets. Glass curtain wall with aluminium frame or stainless steel fixers, pure aluminium panel wall or aluminium plastic alloy panel wall are also well within our capabilities. Our customised design and ‘cut-to-size’ manufacturing will also provide you with options for competitive lead times and cost on construction.
Tempered Glass & HS Glass
Tempered & HS glass is heat-treated glass by heating annealed glass to the softening point and then quenching it by a uniform blast of air evenly to both surface.
When fabricating tempered glass, placement of holes and notches and cutouts should be carefully treated.
Processing standards :
GB/ T9963 ANSI Z 97.1
GB 17841 AS / NZS 2208
BS 6206 EN 12150
ASTM C 1048 EN 1863
JIS R 3206 JIS R 3222 |

The annealed glass is subjected to a special heat-treatment in which it is heated to about 680˚C and afterwards cooled. If it is cooled rapidly, the glass is up to four times stronger than annealed glass, and when broken, it shatters into many small fragments .which prevent major injuries (fully-tempered). Tempered glass is intended for glass facade, sliding doors, building entrances, bath and shower enclosures and other uses requiring superior strength and safety properties. If it is cooled slowly, the glass is twice as strong as annealed glass and the fragments of the broken glass are linear and more likely to remain in the frame (heat-strengthened glass).
Heat-strengthened glass withstands breakage by thermal shock; it is not sensitive to “spontaneous breakage”. The so-called heat-soak test, which is sometimes required to reduce this particular phenomenon in tempered glass, is redundant in the case of heat-strengthened glass. Heat-strengthened glass is mainly used in the following applications:single glazing in spandrels, the exterior sheet of antisolar double glazing with a high energy absorption factor, the exterior and interior sheets of double glazing in spandrels, part of a solar control laminated glass. Heat-strengthened glass, like tempered glass, can be neither shaped nor cut.
