                                            A long-lasting material

                                            There are many reasons for choosing VM ZINC for your roofing and facade projects.
                                            Zinc is naturally resistant to corrosion, is extremely durable and does not require costly
                                            maintenance. Indeed, zinc roofs in Europe give up to a hundred years of loyal service before
                                            needing renovation. In addition, the flexibility, malleability and versatility of zinc, combined
                                            with its pleasing aspect, make it the material of choice for imaginative building projects from
                                            individual homes to commercial complexes, public buildings and private projects.

VM ZINC

A top-performing alloy

VM ZINC is rolled zinc alloyed with copper
and titanium to produce a material with
optimum mechanical and physical
characteristics for building applications,
particularly with regard to the material’s
mechanical resistance and creep resistance.

VM ZINC is composed of very high quality
zinc Z1 (99,995% pure zinc), as defined by
the EN 1179 standard, to which titanium
and copper are added:
• titanium: min. 0.06% - max. 0.20%
• copper: min. 0.08% - max. 1.00%

Copper increases the mechanical resistance
of the alloy, making it harder and stronger.
Titanium increases creep resistance permitting   The PREMIUMZINC

                                                 The European Standard EN 988 has been
                                                 applied since 1997 in 18 European
                                                 countries. This standard imposes very
                                                 stringent specifications for the composition
                                                 of rolled zinc and its physical, mechanical
                                                 and dimensional characteristics, which
                                                 make it an international reference.
                                                 Whilst the VM ZINC brand complies with
                                                 all the specifications of the EN 988 standard,
                                                 we have gone beyond the requirements of

                                              A four-stage production process

                                              Zinc is a naturally occurring metal which is          3 – Rolling
                                              found in large quantities in the form of ore          Three to five rolling operations are performed
                                              in the earth’s crust. All operations, from the        to reduce the slab to the required thickness.
                                              transformation of the ore to the production           Throughout this process, temperature, rolling
                                              of rolled zinc and finished products, are             speed and reduction rate are closely monitored
                                              carried out within the Umicore Zinc Group             and adjusted to obtain the requisite mechanical
                                              to which the VM ZINC brand belongs.                   and dimensional characteristics.
                                              The Smelting Unit transforms the ore into
                                              zinc oxide in a process called “roasting”,
                                              and into a zinc sulphate solution from the
                                              calcinated zinc in a process called “leaching”.
                                              The solution obtained supplies the electrolysis
                                              hall where 99.995% pure zinc is obtained.
                                              After the electrolytic process, the zinc is rolled
                                              in two VM ZINC rolling mills in France.

                                              1 – Alloying
                                              The first stage consists of melting the pure
                                              metal deposited on the cathodes during the
                                              electrolysis process and adding a controlled
                                              amount of copper and titanium in a series of
                                              induction furnaces to produce a liquid alloy.         4 – Slitting into sheets and coils
                                                                                                    One of the final steps involves slitting the

                                              The liquid metal is then transferred to a             weight, width and thickness on specialised
                                              continuous casting machine for solidification         finishing lines.
                                              into a continuous slab, about twelve millimetres
                                              thick and approximately a metre wide.

                                              machine produces a fine, homogeneous
