| Use advice for data set | Scope: The declaration covers galvanized structural steel produced at the production site in Brande, Denmark. The declaration covers all life cycle modules from A1-A5, C1-C4 and D and is based on product-specific data provided by Give Steel A/S and background data from GaBi professional 2020 and Ecoinvent v3.6. System boundary: Type of EPD: Cradle to gate with options. Module A1-A3, A4, A5, B1-B7, C1-C4 and D are considered. Yet, no environmental impacts are associated with modules B1-B7, thus these modules are declared as not relevant or not declared. Modules A1-A3 include the acquisition of all raw materials, products and energy, transport to the production site, the manufacturing of the galvanized structural steel and waste processing up to the end-of-waste state. Module A4 includes the transport of the product to the construction site. Module A5 includes the installation of the product using a diesel truck. Module C1 considers the deconstruction of the structural steel using a truck. In module C2, the demolished steel is transported to a waste processing site, with the waste processing considered in module C3. Finally, module D considers the benefits from recycling the demolished steel parts. | ||
| Technical purpose of product or process | The product can be used as part elements or as an independent static system, where all parts are made of steel. The product is widely used in numerous construction projects. Examples are: Single-story buildings (industrial and storage halls, animal stables, data centres, etc.) Multi-story buildings (offices, residential buildings, car parks, etc.) Bridges (railway bridge, road bridge, pedestrian bridge, etc.) Other structures (Stadiums, convention centres, airports, stations, etc.) | ||

| General comment on data set | This EPD applies to 1 ton of galvanized structural steel. Structural steel constructions from Give Steel are designed and produced according to European design codes and production standards, as well as in compliance with project specifications. While Eurocode 1 and Eurocode 3 apply to the design and civil engineering works, manufacturing is carried out according to EN 1090 for steel construction. Furthermore, these codes and standards outline specific product standards for choosing the most appropriate constitute products for each component. Such standards include EN 10025 which defines the requirements for non-alloy and fine grain weldable structural steels, EN 10219 for cold formed hollow sections and EN 13479 and ISO 544 which sets out the same set of requirements for materials. | ||

| Technology description including background system | This EPD covers 1 ton of galvanized structural steel produced by Give Steel A/S in Brande, Denmark, and the EPD covers the modules A1-A5, C1-C4 and D. The galvanized structural steel constitutes primarily of steel scrap (78%) and primary steel (20%). Welding rod (iron) and galvanization (zinc) account for 1% respectively. The raw materials - flat iron, plate and beams - are brought in, processed, shot cleaned, cut and welded. The process will vary, depending on the involved raw material. The various materials are transported by side loader from our warehouse to the appropriate production machines: Flat iron to the CNC flat iron machine, plate to the CNC plasma cutter and beams to the shot ball cleaner. Flat iron is processed, if necessary, by adding holes and cutting into strips. Plate is plasma cut following 2D models. Beams are shot cleaned and cut to length. Flat iron, steel plate and beams are shot cleaned before production to produce the correct surface. The shot cleaner is always kept full to save power. The steel balls are reused in production until steel dust is all that remains. After cleaning, flat iron and plate are distributed for use as beams and to the welding robot, respectively. Beams and associated plates are stapled together. Beams are then welded, according to design diagrams. When manufacturing welded wedges for robot welding, all parts are assembled from the CNC cutting table and CNC flat iron cutter. Once the parts are collected, they are stapled together according to design diagrams. The stapled wedges are robot welded and sent on. The remaining components are mounted or welded manually. Beams that need to be galvanized are loaded onto a lorry and transported to a subcontractor. After galvanization, the beams are brought back to the factory and stored until delivery to the construction site. Technical data: This EPD is valid for galvanized structural steel of different forms of delivery. Specific information on dimension tolerances, constructional data as well as mechanical and chemical properties can be found in the relevant literature and/or the standards. Declared unit: The declared unit is 1 ton of galvanized structural steel. The galvanization accounts for 1 % of the products weight-%. | ||
