Railway or tramway sleepers (cross-ties) of wood, impregnated

cpc code 31320 covers the production of railway or tramway sleepers (cross-ties) of wood that have been impregnated. These wooden sleepers are a critical component of railway infrastructure, providing a stable and durable foundation for the tracks. The sleeper industry plays a vital role in the broader transportation and logistics sectors, supporting the efficient movement of goods and people across rail networks worldwide.

The production of impregnated wooden railway sleepers typically involves several key steps. First, high-quality timber, often sourced from hardwood species, is carefully selected and cut to the required dimensions. The wood is then subjected to a pressure-treating process, where it is impregnated with preservative chemicals to enhance its resistance to weathering, decay, and insect damage. This impregnation process helps to extend the lifespan of the sleepers and ensures they can withstand the rigors of heavy rail traffic.

The main inputs required for the production of cpc code 31320 items include the raw timber, typically hardwood species such as oak, beech, or pine; specialized machinery for cutting, shaping, and treating the wood; and the chemical preservatives used in the impregnation process. Additionally, the industry relies on a skilled workforce to operate the production equipment and ensure consistent quality standards.

The primary output of this industry is the impregnated wooden railway or tramway sleepers, which are then supplied to 49210 Railway transport services and 42120 Construction of railways and underground railways for use in the construction and maintenance of rail infrastructure. These sleepers are an essential component in the overall rail transportation system, providing a stable and durable foundation for the tracks.
