VMZINC Manufacturing Process

VMZINC, a leading specialist in innovative  zinc solutions for the building industry.

Production, metal roofing and facade manufacturer

Our organisation is dedicated to the value chain. The geographical spread of the Auby (north-east), Viviez (south-west) and Bray-et-Lû (north-west) production sites in France ensures optimum nationwide deliveries. This system is supplemented by other industrial plants in:

  • Belgium
  • Germany 
  • Switzerland 
  • Slovakia (production plants for zinc, copper, galvanized steel and stainless steel pre-formed products and accessories).

With an increasingly international clientele, the large number of sites brings the brand closer to its customers, and improves its quality of service and the efficiency of its shipping logistics.

Production process

Production VMZINC Plants 1


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.

Casting Production VM-BuildingSolutions


The liquid metal is then transferred to a continuous casting machine for solidification into a continuous slab, about twelve millimetres thick and approximately a metre wide. The controlled cooling process within the machine produces a fine, homogenous grain structure.

rolling machine VM BuildingSolutions


Three to five rolling operations are performed to reduce the slab to the required thickness. Throughout this process, temperature, rolling speed and reduction rate are closely monitored and adjusted to obtain the required mechanical and dimensional characteristics.
