About shaping and processing of flat glass

NACE code 23.12 covers the shaping and processing of flat glass, a critical industry that plays a vital role in the construction, automotive, and manufacturing sectors. Flat glass products are essential components in a wide range of applications, from windows and doors to solar panels and electronic displays. This industry's importance extends beyond its direct economic impact, as the availability of high-quality, affordable flat glass contributes to the development and advancement of numerous other industries.

Production process

The production of flat glass typically involves a float glass process. In this method, molten glass is poured onto a large, shallow pool where it spreads and forms a uniform, flat surface. The glass is then slowly cooled, annealed, and cut or shaped as needed. Additional processing steps, such as tempering, laminating, or coating, may be applied to the flat glass to enhance its properties and meet specific requirements.

Production inputs

The flat glass industry relies on a variety of raw materials, including silica sand, limestone, and sodium oxide. These materials are carefully selected and blended to achieve the desired glass composition and properties. Additionally, the industry requires specialized machinery and equipment, such as float glass furnaces, cutting and edging tools, and tempering ovens, to ensure efficient and high-quality production.

Production outputs

The primary outputs of the flat glass industry are sheet glass, float glass, and various processed flat glass products. These outputs are then consumed by a range of other NACE codes, including 23.11 Manufacture of flat glass, 23.13 Manufacture of hollow glass, 25.11 Manufacture of metal structures and parts of structures, 26.11 Manufacture of electronic components, and 41.20 Construction of residential and non-residential buildings, among others.
