Primary data was collected from California Expanded Metal Products Co. (CEMCO) facilities in City of Industry, CA; Denver, CO; Fort Worth, TX; and Pittsburgh, CA. Overall data quality is very good.01All primary and secondary data were collected from four facilties specific to the country under study. Where country-specific or region-specific data were unavailable, proxy data were used. Geographical representativeness is considered to be high.A1-A3 production of cold-rolled steel framing systems consists of coil slitting (decoiling, slitting, and recoiling), roll forming, packaging, and, finally, loading. All primary and secondary data were modeled to be specific to the technologies or technology mixes under study. Where technology-specific data were unavailable, proxy data were used.Lubricants at refineryPolyethylene film (LDPE/PE-LD)Steel hot dip galvanized (version released in 2011)Steel cold rolled coil (version released in 2011)Thermal energy from LPGProductPlastic waste on landfill, post-consumerMunicipal Solid Waste on landfillFerro metals on landfill, post-consumerThese products are manufacturing for use in curtain wall, load-bearing, rough-opening, and ceiling/floor/roof applications.construction_steel_framing_cemco.pngLCI resultAttributionalnoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentAllocation - massThe cut-off criteria for including or excluding materials, energy and emissions data of the study are as follows:
Mass: If a flow is less than 1% of the cumulative mass of the model it may be excluded, providing its
environmental relevance is not a concern.
Energy: If a flow is less than 1% of the cumulative energy of the model it may be excluded, providing its
environmental relevance is not a concern.
Environmental relevance: If a flow meets the above criteria for exclusion, yet is thought to potentially have a
significant environmental impact, it was included.
No processes were neglected or excluded. Capital items for the production processes (machines, buildings, etc.) were
not taken into consideration.This dataset represents 2012 steel framing production by CEMCO in four US plants (City of Industry and Pittsburg, CA;
Denver, CO; and Forth Worth, TX).
All secondary data come from the GaBi 2016 databases and are representative of the years 2007-2015. Therefore, temporal representativeness is warranted.Environmental Product Declaration - Cold-Formed Steel Framing Systems95.02012No statementthinkstepthinkstep2020-01-01T00:00:00.000ILCD format 1.1thinkstep2020-01-01T00:00:00.00000.00.001Data set finalised; entirely publishedthinksteptrueOtherThe EPD owner (source code, database including extension modules and single data sets, documentation) remains property of thinkstep AG. thinkstep AG delivers GaBi licenses comprising data storage medium and manual as ordered by the customer.
