Product Description: HIT-Z-R Anchor Rod

An ultimate-performance anchor rod for injectable hybrid anchors, made from A4 stainless steel, offering the following features:

• Supports very high loads in cracked concrete and seismic applications, meeting ICC-ES and ETA C2 approvals.
• Eliminates the need for hole cleaning when used with HIT-HY 200 adhesive mortars (above 5°C / 41°F), leading to a more reliable and productive solution.
• Allows variable depth of embedment to maximize anchor capacity.
• Features head marking for easy verification of rod length, even after installation.

The product is made from 100% electric arc furnace (arc) produced steel, with 80% secondary (recycled) material content. This includes approximately 30% pre-consumer share (24% of steel components) and 70% post-consumer share (56% of steel components).

Applications

• Fastenings in cracked and uncracked concrete with Hilti HIT-HY 200.
• Seismic anchoring applications, such as bracing of reinforced concrete buildings.
• Anchoring structural steel connections (e.g., steel columns, beams).
• Outdoor applications or fastenings in corrosive environments when used with HIT-Z-R.

Product Life-Cycle

System Boundary

This EPD covers the life-cycle modules listed below:

Note: Modules not declared = MND. Modules not relevant = MNR.

Manufacturing and Packaging (A1-A3)

This stage covers the manufacturing of raw materials, packaging, and ancillary materials, including fuels used by machines and waste handling. It also accounts for material losses during manufacturing and electricity transmission. A market-based approach models the factory's electricity mix.

Transport of raw materials (A1) uses >32 metric ton EURO 5 lorries over 600-670 km. A 1% production loss is considered. Manufacturing involves sheet rolling and wire drawing, powered by green electricity certificates (wind energy). Packaging uses cardboard boxes. Ancillary materials include wax coating and compressed air. Transport of packaging and ancillary materials uses >32 metric ton EURO 5 lorries within Europe.

The use of green energy is confirmed via contractual instruments (GOs, RECs).

Transport and Installation (A4-A5)

Transportation impacts from final product delivery to the construction site (A4) include fuel emissions and production impacts. Transport to the installation site (A4) involves two legs: 825 km by road (16–32 metric ton EURO 5 lorry) and 3540 km by sea (container ship).

Installation (A5) assumes no material loss, additional materials, or energy consumption. End-of-life (EoL) assumptions for installation waste: 83% recycled, 8% incinerated, 9% landfilled. Transport of A5 waste is 50 km by road (16–32 metric ton EURO 5 lorry).

Product Use and Maintenance (B1-B7)

Emissions due to installation are considered negligible, as installation is brief and uses simple tools. The product is embedded in the building structure, requiring no routine maintenance. Air, soil, and water impacts during the use phase have not been studied.

Product End of Life (C1-C4, D)

In a global average scenario, 85% of the steel is assumed to be recycled, with the remaining 15% sent to landfill. Actual recyclability may vary by region.

Manufacturing Process

The manufacturing process involves the following steps:

• Steel wire is processed through Extrusion.
• The extruded material then undergoes Helical rolling.
• Separately, the steel wire is Coated.
• Finally, the coated product is Packaged.

Life-Cycle Assessment

Cut-Off Criteria

The study includes all mandatory modules and processes as per the reference standard and PCR. No hazardous materials or substances are excluded. All major raw material and energy consumption is included. Neglected unit processes are less than 1% of total mass/energy flows, and module-specific neglected flows do not exceed 5% of energy usage or mass.

Excluded from the study are: production of capital equipment, construction activities, infrastructure, maintenance and operation of capital equipment, personnel-related activities, and energy/water use related to company management and sales activities.

Validation of Data

Data collection for production, transport, and packaging used site-specific information. Upstream process calculations relied on generic data from the Bibliography. Manufacturer-provided specific and generic data were used for the manufacturing stage. The analysis was performed using the One Click LCA EPD Generator with the 'Cut-Off, EN 15804+A2' allocation method and characterization factors according to EN 15804:2012+A2:2019/AC:2021 and JRC EF 3.1.

Allocation, Estimates and Assumptions

Allocation is applied when material, energy, or waste data cannot be measured separately. All allocations follow reference standards and the applied PCR. The study's allocation methods are:

This EPD is product and factory specific.

LCA Software and Bibliography

This EPD was created using the One Click LCA EPD Generator, adhering to ISO 14040/14044 standards. It utilizes Ecoinvent v3.10.1 and One Click LCA databases for environmental data, with the 'allocation, Cut-off, EN 15804+A2' methodology.

Environmental Impact Data

The following tables present estimated impact results. These are relative statements and do not indicate end points, threshold values, safety margins, or risks.

Core Environmental Impact Indicators – EN 15804+A2

¹⁾ GWP = Global Warming Potential; ²⁾ EP = Eutrophication potential. Required characterisation method and data are in kg P-eq. Multiply by 3,07 to get PO4e; ³⁾ POCP = Photochemical ozone formation; ⁴⁾ ADP = Abiotic depletion potential; ⁵⁾ EN 15804+A2 disclaimer for Abiotic depletion and Water use and optional indicators except Particulate matter and Ionizing radiation, human health. The results of these environmental impact indicators shall be used with care as the uncertainties on these results are high or as there is limited experience with the indicator.

Additional (Optional) Environmental Impact Indicators – EN 15804+A2

⁶⁾ EN 15804+A2 disclaimer for Ionizing radiation, human health. This impact category deals mainly with the eventual impact of low-dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator; ⁷⁾ SQP = Land use related impacts/soil quality.

Use of Natural Resources

⁸⁾ PER = Primary energy resources.

End of Life – Waste

End of Life – Output Flows

Environmental Impacts – EN 15804+A1, CML

Environmental Impacts – GWP-GHG - The International EPD System

⁹⁾ This indicator includes all greenhouse gases excluding biogenic carbon dioxide uptake and emissions and biogenic carbon stored in the product as defined by IPCC AR 5 (IPCC 2013). In addition, the characterisation factors for the flows - CH4 fossil, CH4 biogenic and Dinitrogen monoxide - were updated in line with the guidance of IES PCR 1.2.5 Annex 1. This indicator is identical to the GWP-total of EN 15804:2012+A2:2019 except that the characterization factor for biogenic CO2 is set to zero.
