Zinc coated and painted steel structures (SIA LSEZ RT metāls)

The average EPD (type: Cradle to gate with options, modules C1-C4 and module D (A1- A4, C, D)) is based on LCA of the custom made zinc coated steel structures, manufactured in Liepāja, Latvia. This EPD contains results of two sub-types: zinc coated steel structures and zinc coated and additionally painted steel structures. The calculation is based on 1 kg of zinc coated steel structure with a share of 93,27% steel materials and zinc coated and painted steel structure with a share of 90,94% steel materials. Kiwa-Ecobility Experts shall not be liable with respect to manufacturer information, life cycle assessment data and evidence.

Zinc coated or hot-dip galvanized steel structures are used in various areas of construction, for example construction of bridges, telecommunications towers, engineering, industrial and public buildings, as well as in the agriculture and energy industry. Hot-dip galvanizing is especially valued in objects that are located in an aggressive, corrosion-enhancing environment. The steel structures are manufactured according to EN 1090-2, up to EXC 4, and are CE marked. UN CPC code: 421 Structural metal products and parts thereof. The steel structures of industrial and civil objects are made according to the developed drawings. The manufacturing contains the following processes: • Extraction and delivery of raw materials; • Cutting; • Assembling; • Welding; • Sand blasting; • Coating (hot-dip galvanization (external treatment) and additional priming and painting); • Storage; • Transportation (delivery of finished products). Since hot-dip galvanization is outsourced process, A1 for zinc layer does not include transportation. Transportation is included in A3 (incl. both ways).

The area of application of zinc coated steel structure includes mostly outdoor residential and commercial construction elements, where high corrosion protection is needed (galvanized balconies, car ports, stairs, railings, balustrades, canopies, etc.), street furniture (fencing, walkways, gates), as well as various leisure, sport and playground elements (swings, football goals, railings, etc).
