| Technical purpose of product or process | A NC-Bolt is a combination bolt that is installed for immediate support of rock in tunnels or slopes. It is immediately anchored when installed by an expansion shell providing work safety and can be fully grouted at a later stage, allowing it to be classified as permanent support. NC-Bolt with PC-coat provides market leading service life in the most demanding environments. The NC-bolt is a rebar-based combination bolt made from scrap/recycled steel material. It has a grouting system made of a steel head and a special designed plastic tube to ensure perfect grouting and full anchoring capacity. All steel parts except the expansion shell (it has only a temporarily function) has Pc-Coat® as the standard corrosion protection. Pc-Coat® is a duplex coating system providing the optimal corrosion protection to ensure long service life in all conditions. Pc-Coat™ is suitable for use in all atmospheric corrosion classes, included CX, according to EN ISO 12944-2:2017. This EPD is based on complete bolt with all accessories and spherical plate. |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
