Carburisers and frothers – wholesale sales
As a company with many years of experience in the energy raw materials sector, we specialize in the wholesale sale of carburizers and foaming agents, as well as other solid fuels such as coal, coke, and biomass. Every stage of our operations – from sourcing raw materials, through quality control, to final delivery – undergoes thorough verification, which allows us to provide our clients with products of the highest standard.
With over 30 years of experience in distribution, we fully understand the needs of the industry and can flexibly adapt our offer to the specific requirements of each plant. The carburizers and foaming agents we offer come exclusively from reputable producers with whom we maintain long-standing business relationships and exclusive agreements. This enables us to guarantee constant availability, offer competitive purchase conditions, and ensure rapid delivery – including in a “just-in-time” model.
Working with K Investments means reliability, top quality, and a personalized approach to every order – regardless of its scale or destination.
In order to best match our services to the client’s expectations, we also offer the possibility to negotiate our own contract terms, as well as legal and financial support.
We make sure that the ordered Carburisers and frothers reach the indicated place as quickly as possible. For this reason, we export carbonators by sea and river, as well as by road and rail.
We also attach great importance to proper protection of the goods before shipment, which allows us to guarantee the high quality parameters of the raw materials we distribute.
