Flat toughened glass is produced by common glass which was cooled suddenly when heated to soft point, the producted compress and stress saner the two side then produce tenile stress make the whole stress balance. Maximum:2440mm*7500nn Niminum:200mm*300mm Thickness:4-19mm.
Safety glass used the door, window, building and table. Wooden packing.
Tempered glass:in modern architecture, the designer has increasingly high requirements on safety and strength of the glass that is why tempered glass is widely used.Shanghai tob produces tempered glass and use a special heat treatment for the ordinary annealed glass, which results in the uniform stress on the surface as well as the tension stress inside of the glass to increase strength. Characteristics: The strength of tempered glass is four times bigger than that of the ordinary annealed glass When destroyed by outside force, the tempered glass forms bean-like particles to reduce the danger for human body It withstands the sudden change of temperature.(for instance, 5mm tempered glass withstands a temperature change of 200℃) The half-tempered glass has a very sound flatness and less optical aberration The half-tempered glass can be further processed as colored tempered glass which is excellent for decoration purpose Applications: Auto motives, trains, ships, construction outer wall, partition for inner decoration, shower room Furniture, automatic door, elevator, fireplace, etc. Specifications: Thickness for ordinary glass: 3--19mm Max.Size: 2400*8000mm Min.Size: 24*24mm Inner packing:blistering paper Outer packing:fumigation wooden case
