REXI toughened glass is glass after the heat treatment process. It is characterized by the formation of compressive stress on the surface layer, mechanical strength and thermal shock resistance is improved, and has a special debris status.In China toughened glass factory, material used in the production should have quality that is consistent with the corresponding product standards. For special requirements, the material used in the productionâ??s quality should be determined by both China toughened glass supplier and costumer.Its thickness is generally not less than 4mm, and after tempering it cannot be under any further processing like cutting, drilling holes, grooving, notching and so on.The aperture is generally not less than the thickness of the glass, if it need to be drilling, the distance from the edge of the hole to the edge of the product should not be less than 2 times of the thickness of the glass, the distance between two holes should not be less than 2 times the thickness, the distance between the edge of the hole and the corners should not be less than 6 times of glass thickness. So toughened glass price is related to the shape and processing.For China toughened glass manufacturers, packaging should be used wooden boxes or cases, the cases should be easy loading, unloading and transportation. Each case needs to be packed with stuff of the same thickness and size.Between the pieces of glass and between the glass and the case frame we have to take protective measures to prevent damage and scratches on the surface. Packaging signs should be consistent with the provisions of the relevant national standards, each case ought to be marked the cautions like "upside, move carefully, be cautious of broken and wet" and other signs or words. During transportation, toughened glass should be firmly fixed to prevent sliding or dumping, there should be rain-proof measures. Products should be stored in non-condensing or wet proof facilities.
