Cold-rolled steel profiles for framing and partition systems
Technical purpose of product or process This EPD is carried out for the steel profile sections manufactured by Steel Formed Sections Ltd. The raw material is hot dipped sheet rolled galvanised steel, grade DX51D+Z steel for forming. The steel profile sections are manufactured in accordance with EN 14195:2014 Metal framing components for gypsum board systems. Definitions, requirements and test methods. The steel coils are placed on a coil holder, and the steel strip is fed through a series of specially shaped rollers that form the steel to any required profile. Whilst being rolled, the steel sections are punched to create service holes or any other cut-out features as required. Once the required length of profile has been achieved, the profile section is cut to size. The cut sections are then stockpiled before being despatched to the customer. Off-cuts from the cutting process are collected and sent to a local recycling operation.
General comment on data set Data flows have been modeled as realistically as possible. Data quality assessment is based on the principle that the primary data used for processes occurring at the production site is selected in the first instance. Where this is not available, other reference data is selected from appropriate sources. The dataset is representative for the production processes used in 2019. The process descriptions and quantities in this study are reproducible in accordance to the reference standards that have been used. The references of all sources, both primary and public sources and literature, have been documented in the LCA report. The ‘polluter pays’ and ‘modularity’ principles have been followed. The cut-off criteria of section 6.3.5 of EN 15804 have been followed. Allocation has been done on a mass basis. The measurement of environmental impacts uses the CML 2 baseline method In addition, to facilitate the reproducibility of this LCA, a full set of data records has been generated which can be accessed via the EcoChain tool. This data portfolio contains a summary of all the data used in this LCA, and correspondingly, in the Steel Formed Sections Ecochain account.

Technology description including background system A1. Raw materials supply This module considers the extraction and processing of all raw materials and energy which occur upstream to the steel profile manufacturing process, as well as waste processing up to the end-of waste state. A2. Transport of raw materials to manufacturer This includes the transport distance of the raw materials to the manufacturing facility via road and sea. The ecoinvent record for road transport to site used is: market for transport, freight, lorry 16-32 metric ton, EURO6. A3. Manufacturing This module covers the manufacturing of the Steel Formed Sections steel profiles and includes all processes linked to production such as, forming, packing and internal transportation. Use of electricity, fuels and auxiliary materials used during production is taken into account as well.
