Products

Core products of Altai-Koks are produced by five coke-oven batteries. The fifth coke-oven battery complex commissioning will enable the Company to produce 4.4 mln tons of coke. This includes a Class 80 mm coke coal foundry. This fraction is highly demanded in the market and is applied in manufacture of hi-tech thermal insulation materials.
