We mainly invest a lot in Ferro Silicon and Silicon Metal production line for manufacturing Silica Fume and densification lines. Topken has six Silica Fume bases in different places in China. As per different quality, we supply Silica Fume to different customers in different areas, such as Refractory Materials, Concrete (HPC), and Grout. Now our production capability is over 2500MT per month.

We have good cooperative relationship with Chinese Building Material Academy and Shanghai Building Material Research Institute in application technology. When our Silica Fume products are used in an engineering project, we could supply technical support to our customer. That is very important in China, because not every construction company or RMC company is familiar with Silica Fume, especially for new users. Now more and more important engineering projects attach importance to Silica Fume application in China.

Topken is now a main producer and supplier in Chinese important engineering, such as Shanghai East Sea Bridge, Tianjin (Xingang) Harbor, Gezhouba Dam, and Yellow River Engineering.
