Products & Services
Three business lines, one technical focus
Everything we supply and advise on serves a single objective: a stable, efficient, long-lasting reduction cell.
Lining Materials
We supply high-quality lining materials for aluminium smelters, including cathode blocks, refractory bricks, and silicon carbide slabs, engineered for durability and thermal performance in demanding smelter environments.

Collector bar technologies, visualised
Engineering-style visualisations of our collector bar range. Every product is manufactured strictly to the customer's approved drawings and specifications, ensuring precise dimensional accuracy for each project.
Copper TOP Insert Collector Bars
A copper insert is seated in a channel milled along the top face of the steel bar — placing the highest-conductivity path closest to the cathode block. The result is a flatter current distribution, reduced cathode voltage drop and improved energy efficiency, while the steel body retains the mechanical and thermal behaviour your assembly process is built around.
- Steel body — cast-in strength and proven assembly compatibility
- Copper insert — high-conductivity core along the bar length
- Top insert design — conductor positioned nearest the cathode block
- Improved conductivity — lower CVD and specific energy consumption
Low Electrical Resistivity Steel Collector Bars
Controlled-chemistry steel selected for reduced resistivity, lowering cathode voltage drop without changing your assembly practice.
Copper Insert Collector Bars
Steel body with a narrow copper strip set into the top face to shape current distribution and cut ohmic losses.
