Tempered Glass/safety Glass

Toughened glass is a safety glass that has undergone processes of controlled thermal treatment to increase its strength. Also known as 'Tempered glass', toughened glass is made from annealed glass that has been heated to approximately 650â?°C and then rapidly cooled, making it four times stronger than ordinary glass. Due to the increased heat treatment and rapid cooling of the glass, the treatment produces different physical properties. This results in compressive stress on the surface and improved bending strength of the glass. Before toughening, the glass must be cut to the correct size or pressed to shape. The Process of Toughening The glass is carried by rollers and goes through the furnace. Three types of modes are used to heat the glass - conduction, convection, and radiation. While the rollers help to conduct the heat, the coils enable radiation of heat. This ensures that the glass is evenly heated on every side. By blasting air on both the surfaces, the heated glass is then cooled uniformly.

JHG tempered glass is from 2-25mm , sizes from 100x100mm to 18000x3300mm . The tempered glass is widely used for fence , furniture ,window, shower door ,curtain wall , floor .

It is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass, about four times stronger than annealed, glass. When broken, tempered glass fractures into small, relatively harmless pieces, it is widen used for window, door, railing, furniture, vehicle.

JHG silk-screen printed glass is one kind of decorative glass made by printing layer of ceramic ink on the surface of glass through the screen mesh for tempering or heat-strengthening process after. As a result silk-screen printed glass is durable, scratch-proof, solar shading and with anti-glare effect. Silk screen glass is widely usded for architecture ,home application ,furniture , auto window shild. Max size 2440*3660mm ,All colour is available .
