About Coil
Coil S.A./N.V. is a Belgian company headquartered in Landen, founded in 1972, specializing in the continuous anodizing of aluminium flat products in coil form, sheets and architectural panels. At the headquarters and production site in Landen (Belgium), there are three continuous anodizing lines – two of which specialize in thinner metal gauges – as well as a next-generation anodizing line for sheets and architectural panels; a vertical anodizing line enables the finishing of pre-fabricated profiles, extrusions and complex structures such as Architectural Mesh. At the German site in Bernburg (Coil GmbH), two continuous anodizing lines for heavy sheet gauges are in operation, mainly for the architectural market. The material range includes aluminium and pure aluminium; coating thicknesses of 5–20 µm on metal gauges of 0.5–3.0 mm are offered, with finishes such as Natural, Bronze B10–B85, Copper, Gold and Rosegold in Mill Finish, Brite or Brush. In addition, the company offers honeycomb and sandwich panel bonding, forming after anodizing (bending, roll forming) as well as cut-to-length. Customers include aluminium flat rolling mills such as Aluminium Duffel, Constellium, Hydro, Novelis and Speira as well as luxury brands such as Rimowa and Bulthaup. The company employs 125 staff across both sites and has been listed on Euronext Growth in Paris (ALCOI.PA) since 1996.

Materials & Processes
Aluminium
Flat products in coil form, sheets and panels, metal gauges 0.5–3.0 mm, for architectural and industrial applications.
Pure Aluminium
Base for high-quality, decorative and corrosion-resistant anodic oxide surfaces.
Continuous Coil Anodizing
Electrochemical process for producing durable, UV-resistant anodic oxide layers (5–20 µm) on strip and sheet.
Roll Forming after Anodizing
The flexible anodic oxide film allows bending and roll forming after finishing without loss of appearance or protection.
Honeycomb/Sandwich Panel Bonding
For low- to medium-temperature-suitable bonding processes for honeycomb and sandwich panels.
