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

cpc code 3132 covers the production of railway or tramway sleepers (cross-ties) made of impregnated 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 of these wooden sleepers is an important industry that supports the broader economy by enabling the efficient movement of goods and people.

Production process

The production of impregnated wooden sleepers typically involves several key steps. First, high-quality timber, often sourced from hardwood species, is selected and cut to the required dimensions. The timber is then subjected to a process of impregnation, where preservative chemicals are infused into the wood to enhance its durability and resistance to weathering, pests, and decay. This impregnation process is crucial to ensure the sleepers can withstand the demanding conditions they will face in railway and tramway applications. Finally, the treated sleepers are carefully inspected and prepared for distribution to construction and maintenance projects.

Production inputs

The main inputs required for the production of cpc code 3132 wooden sleepers include high-quality timber, typically hardwood species such as oak or beech, as well as specialized chemical preservatives for the impregnation process. Additionally, the industry relies on specialized machinery and equipment for cutting, shaping, and treating the timber, as well as transportation and logistics infrastructure to deliver the finished sleepers to their final destinations.

Production outputs

The primary output of cpc code 3132 is the production of impregnated wooden sleepers for use in railway and tramway infrastructure. These sleepers are essential components that are consumed by 4921 Railway transport services and 4922 Urban and suburban transport services, as well as 4213 Construction of railways and underground railways and 4299 Construction of other civil engineering projects n.e.c. for the construction and maintenance of transportation networks.
