About float glass and surface ground or polished glass, in sheets

cpc code 37113 covers the production of float glass and surface ground or polished glass in sheet form. This industry plays a crucial role in the construction, automotive, and manufacturing sectors, providing essential materials for a wide range of applications. The production of these specialized glass products is a highly technical process that requires precise control and specialized equipment, making it an important part of the broader glass manufacturing industry.

Production process

The primary production technique for float glass involves a continuous process where molten glass is poured onto a large, flat surface, typically made of metal. As the glass spreads out, it forms a smooth, uniform surface, creating a flat, defect-free sheet of glass. For surface ground or polished glass, the sheets are then subjected to additional processing, such as grinding and polishing, to achieve the desired surface finish and optical properties.

Production inputs

The main inputs required for the production of float glass and surface ground or polished glass include high-quality raw materials such as silica sand, soda ash, and limestone. Specialized equipment, such as float glass furnaces, grinding and polishing machines, and annealing ovens, are also essential for the manufacturing process. Additionally, skilled labor and precise process control are necessary to ensure the consistent quality of the final products.

Production outputs

The primary outputs of cpc code 37113 are sheets of float glass and surface ground or polished glass, which are used in a variety of applications. These glass products are often consumed by industries such as 37112 Toughened or laminated glass, in sheets, 37114 Glass in sheets, n.e.c., and 41210 Builders' joinery and carpentry of wood, where they are used for windows, doors, mirrors, and other architectural and construction applications.
