CPC v2.1 Code: 31109
About railway or tramway sleepers (cross-ties) of wood, not impregnated
cpc code 31109 covers the production of railway or tramway sleepers, also known as cross-ties, made of untreated or unimpregnated wood. These sleepers play a crucial role in the construction and maintenance of railway and tramway infrastructure, providing a stable foundation for the tracks. As a key component of transportation networks, the production and supply of these wooden sleepers is an important industry that supports the broader economy.
Production process
The production of railway or tramway sleepers (cross-ties) of wood, not impregnated, typically involves several key steps. First, the raw timber is sourced and cut to the required dimensions. The wood is then dried to the appropriate moisture content, either through natural seasoning or using specialized drying equipment. Next, the sleepers are shaped and finished, often with the use of power tools and specialized machinery. Finally, the sleepers are inspected, treated if necessary, and prepared for distribution and installation.
Production inputs
The main inputs required for the production of cpc code 31109 items include raw timber, typically hardwood species such as oak, beech, or pine. Specialized woodworking machinery, such as saws, planers, and sanders, are also essential for the manufacturing process. Additionally, the industry may rely on transportation services to move the raw materials and finished products, as well as energy sources to power the production facilities.
Production outputs
The primary output of this industry is the production of railway or tramway sleepers (cross-ties) of wood, not impregnated, as described by cpc code 31109. These sleepers are then consumed by the 49100 Railway transport services and 49200 Urban and suburban passenger land transport industries, which use them in the construction and maintenance of railway and tramway infrastructure.
