Qingdao Cngrow 3mm, 4mm, 5mm, 6mm clear tempered glass for green house
1. Advantages: High light transparency. 2. Separate package: One package for each set of greenhouse. 3. 20 years of temepred glass producing and trading experience.
Introduction for tempered glass:
Tempered glass is made by heating flat glass to its softening temperature and suddenly chilling it with jets of cold air. So the surface of the glass will be under powerful compressive stress and the interior will be with severe tensile stress. In consequence, the impact applied to the glass will be overcome by the compressive stress on the surface to assure safety. There are tempered glass and half tempered glass according to different strength.
Qingdao Cngrow glass applies continuous tempering furnace with advanced technology, high production capacity and great smoothness.
Features: 1. It is safety glass. 2. 4-5 times stronger than float glass. 3. 3-4times stronger resistance to thermal breakage than annealed or heat strengthened glass. 4. Once breakage occurs, the glass disintegrate into small cubical fragments, which are relatively harmless to human body. 5. 2.5-3 times higher temperature changing endurance than ordinary annealed glass. It withstands abrupt temperature change of 300 Centigrade.
