| Use advice for data set | Scope: This Environmental Product Declaration in accordance with EN 15804 covers the life cycle of 1 kg of natural rolled zinc – Blank-Zinc manufactured on the productions plant of VM BUILDING SOLUTIONS (Auby and Viviez - France) representing the average production for 1 year. This EPD covers the natural rolled zinc from VMZINC only. The natural rolled zinc from VMZINC covered by this EPD can be used in buildings as roof, faade or rainwater systems. System boundary: This declaration is a Cradle to Gate with options. It covers modules A1 to A3, modules C1, C2, C3, C4 and modules D. The aggregated modules A1-A3 includes: •The manufacturing and transport of raw materials (Ti, Cu, Zn etc.), •The manufacturing of the natural rolled zinc, •The manufacturing of the energy resources (electricity, thermal energy, auxiliaries), • The manufacturing, the transport and the end of life of the packaging (including loads and benefits for electricity and thermal energy), • The end of life of the process wastes. Module C1 corresponds to the De-construction. The dismantling of zinc laminated roofing and facade systems is done manually. Module C2 corresponds to the transport to module C4. Module C3 includes pre-treatment before recycling. Module C4 corresponds to landfill. Module D includes re-melting and avoided impacts due to recycling of old rolled zinc. | ||
| Technical purpose of product or process | The natural rolled zinc in sheets and coils is used in numerous building applications: - roof and faade cladding (CE-marked based on EN14782:2006, Self-supporting metal sheetfor roofing, external cladding and internal liningor EN14783:2013, Fully supported metal sheet andstrip for roofing, external cladding and internal lining) - interior use - roof drainage systems (gutters, downpipes andaccessories according to EN612) - Flashings, coverings, - roof drainage systems (gutters, downpipes andaccessories according to EN612) - Ornaments under the brand name of "Ateliers dArtFranais. | ||

| Technology description including background system | The manufacturing of rolled VMZINC takes place in 5 stages (same for both site) : 1.Pre-alloying: An alloy comprising copper, titanium andaluminium is prepared at 650°C in an alloy furnace. This masteralloy is put in a second smelting furnace with the refined zinc. 2.Smelting: Refined zinc cathodes and ingots are smelted inthe first induction furnace at 500°C and then are put in asecond smelting furnace with the master alloy. The finishedalloy is fed into the casting furnace. This loads the continuouscasting machine at 500°C. 3.Casting and cooling: The molten metal is transferred into acontinuous casting machine to harden there into the form of anapprox. 12-millimetre-thick and one metre wide continuous caststrand. The controlled cooling process in the systemguarantees a fine, homogenous grain size. 4.Rolling: The cast strand is rolled into the desired thickness inthree to five rolling operations. In the course of this process thetemperature, rolling speed and degree of reduction areconstantly monitored and adapted to achieve the desiredmechanical properties and dimensions. 5. Stretching and cutting: The final stages include stretchingand cutting the rolled zinc into sheets and coils into the desireddimensions and weights. The two production plants where natural rolled zinc is producedare certified /ISO 9001/ (Quality management control). Technical data: The main constructional data are presented in the following table: Declared unit: The declared unit is 1 kg of natural rolled zinc – Natural from VMZINC | ||
