Fabricated steel reinforcing bars manufactured by DIACO

Figured rebar Figured rebar is part of the Fabricated steel reinforcing bars resulting from a cold-forming process. This process involves cutting and bending the steel to the required dimensions, shapes, and angles specified by the client's structural design. Figured rebars are transverse reinforcement elements made from deformed, smooth, or grooved bars, bent into shapes such as S, C, U, rectangles, and circles. It is used as transverse reinforcement in beams and columns, absorbing shear and torsional stress, and providing confinement to the main reinforcement. Heavy rebar shapes Heavy Rebar Shapes are part of the Fabricated steel reinforcing bars, resulting from a cold-forming process. This process involves cutting and bending the steel to the required dimensions, shapes, and angles specified by the client's structural design. Heavy Rebar Shapes rods are straight or bent bars shaped like L, U, or C, used as longitudinal reinforcement. This is designed to absorb tensile and compressive stress in concrete structures.

Ownership and limitation on use of EPD

Limitations

For two EPDs to be comparable, they shall be based on the same PCR (including the same first-digit version number) or be based on fully aligned PCRs or versions of PCRs; cover products with identical functions, technical performances and use (e.g. identical declared/functional units); have identical scope in terms of included life-cycle stages (unless the excluded life-cycle stage is demonstrated to be insignificant); apply identical impact assessment methods (including the same version of characterisation factors); and be valid at the time of comparison.

Ownership

The EPD Owner has the sole ownership, liability, and responsibility for the EPD.

Heavy Rebar Shapes rods are straight or bent bars shaped like L, U, or C, used as longitudinal reinforcement. This is designed to absorb tensile and compressive stress in concrete structures.
Technical purpose of productDIACO produces steel reinforcement products for concrete at its Cota, Sabaneta, Pereira, Cali, Cartagena, Bucaramanga, Neiva and Santa Marta Plants in Colombia, in accordance with national and international standards. The portfolio includes Fabricated steel reinforcing bars, all designed to provide transverse and longitudinal reinforcement, absorbing shear, torsional, tensile, and compressive stresses in concrete structures.
Manufacturing or service provision description Figured rebar: The process begins with the arrival of raw materials (Wire rod wire, ribbed) at the plant, where they are stored according to their specifications and then transferred to the stirrup machines. In these machines, the coil is threaded, straightened, and bent into the shape requested by the customer. The final product is packaged according to its size and shape in big bags or tied with smooth wire or annealed wire and finally labeled for dispatch to the customer. Heavy rebar shapes: This process starts with the reception of raw materials (ribbed or smooth bars). Once received, the bars are placed in the raw material storage area and, depending on production needs, are transferred to the production lines. These lines consist of continuous roller paths that guide the bars through shearing for cutting and then to bending machines that shape the cut bars according to the dimensions and forms requested by the customer. The shaped product is bundled and moved to the storage area to be loaded and dispatched by the logistics department to the final customer.

Technology description including background systemThe declared products are fabricated steel reinforcing bars, including figured rebar and heavy rebar shapes, manufactured through cold-forming processes at DIACO facilities. These products are used as transverse or longitudinal reinforcement in concrete structures to resist tensile, compressive, shear, and torsional stresses. The products are mainly composed of steel scrap (approximately 91.9% by mass), with minor inputs of calcitic lime, anthracite, iron ore, and auxiliary materials used in steelmaking. No biogenic materials are present.

Data quality assessment

Description of data quality assessment and reference yearsDirect data obtained from DIACO is representative for 2024. According to ISO 14044, data validity verified during the collection process to provide evidence that the quality criteria required for the intended application are met. The data quality level and criteria used were based on the Product Category Rules (GPI 5.0.1, section A.5.4), the EN 15804:2012+A2:2019/AC:2021 standard (Annex E), and the PCR Construction Products v2.0.1, section 4.6.5.Data quality assessment was carried out using the following quality levels: very good, good, fair, poor, and very poor.

Additional environmental information

DIACO is certified under ISO 14001:2015 and ISO 9001:2015.Product variation informationThis EPD covers multiple products included within the same product family. The table below presents the variation in environmental results among products for each impact category, considering total results from modules A1 through C4. Declared results in this EPD correspond to representative average values.

Basic impact categories (variation versus representative value)Impact category Min / Max

Global Warming Potential – Total (GWP-total): +17% / -13%

Global Warming Potential – Fossil (GWP-fossil): +8% / -25%

Global Warming Potential – Biogenic (GWP-biogenic): +1% / -4%

Global Warming Potential – Land use and land use change (GWP-luluc): +1% / -4%

Ozone Depletion Potential (ODP): +22% / -66%

Acidification Potential (AP): +4% / -11%

Eutrophication Potential – Freshwater (EP-freshwater): +1% / -3%

Eutrophication Potential – Marine (EP-marine): +3% / -8%

Eutrophication Potential – Terrestrial (EP-terrestrial): +3% / -9%

Photochemical Ozone Creation Potential (POCP): +4% / -11%

Abiotic Depletion Potential for Minerals and Metals (ADPE): +3% / -1%

Abiotic Depletion Potential for Fossil Resources (ADPF): +7% / -21%

Water Deprivation Potential (WDP): +2% / -5%

Description of how the averages have been determinedThe average value was determined by considering the included products and applying a weighting based on their respective production volumes.
