Unworked glass, flat glass and pressed or moulded glass for construction; glass mirrors

CPC v2.1 Code: 3711

About unworked glass, flat glass and pressed or moulded glass for construction; glass mirrors

cpc code 3711 covers the production and processing of various types of glass for construction and other applications. This industry plays a vital role in the broader economy, providing essential materials for the building and construction sector, as well as for the manufacture of mirrors and other glass products. The glass produced under this code is a fundamental component in the construction of residential, commercial, and industrial structures, contributing to the development of modern infrastructure and architectural design.

Production process

The main production techniques used in this industry involve the melting and shaping of raw materials, such as sand, soda ash, and limestone, to create different types of glass. This process typically includes steps like batching, melting, forming, annealing, and finishing. Flat glass is often produced through the float glass process, where molten glass is poured onto a large, shallow pool and allowed to spread and cool, creating a smooth, uniform surface. Pressed or moulded glass, on the other hand, is shaped using molds to create specific forms and designs.

Production inputs

The primary inputs required for the production of glass under cpc code 3711 include raw materials like silica sand, soda ash, limestone, and various other minerals and additives. Specialized equipment, such as furnaces, forming machines, and annealing ovens, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce, including glass technicians, engineers, and operators, to ensure the quality and efficiency of production.

Production outputs

The main outputs of this industry are various types of glass products, including flat glass, tempered glass, laminated glass, and pressed or moulded glass. These materials are used in a wide range of applications, such as the construction of 4100 Buildings and building construction, the manufacture of 3720 Glass and glass products, and the production of 3812 Mirrors and mirror glass. The glass produced under cpc code 3711 is an essential component in the construction, automotive, and furniture industries, among others.
