Announcement: P-D and BRCC long-term exclusively distribution alliance


JIAOZUO BEIXING REFRACTORIES CO., LTD (BRCC) and the P-D Refractories Group (PDR) have established  a long-term and exclusive sales alliance, cooperating in the fields of manufacturing, distribution and the further development of special refractory materials, such as silicon carbide (SiC), light weight insulation firebricks, carborundum ramming materials, high alumina castables and graphite products for the global aluminium industry.
Extensive long-term groundwork leading to this cooperation has now reached a synergy between the two companies, resulting in a synchronization of our quality control and R&D departments. By sharing our know-how, we can now assert that products from our Chinese partner are of the same high quality as of those our customers expect from the P-D Refractories Group.

Since November 20th 2018, marketing and the accountability for technical support and sales, have now been divided into regions: BRCC focusing their marketing activities mainly in China and a few outlying regions, PDR focusing worldwide, but excluding the above mentioned BRCC fields of operation.

This alliance allows us to provide our customers a complete package of refractory products for aluminium reduction cells, thus simplifying the tendering and ordering process for our customers and ultimately resulting in considerable cost reduction.

We are delighted to make this new announcement and are looking forward to our new joint venture.

Precision-finished by Dr. C. Otto


On the 23.11.2018 P-D Refractories commissioned a third five-axis CNC machine at their site Dr. C. Otto located in Bochum. With a dimensional accuracy of 0.1 mm and a breathtaking speed of 25 cm/sec, extremely large refractory blocks can now be ground, cut and milled at this location.

In December 2017, the Ɛpsilon Solution™ basin delivery in P-D fused mullite was concluded and then, as reported on site by Mr. Uwe Pottetz, Project and Product Management P-D Glasseiden GmbH Oschatz, it was “wonderfully” heated.

P-D Refractories makes future-oriented investments at the Wetro site


This year P-D Refractories is investing around EUR 1.2 million in the expansion of a new post-processing at the Wetro site.

The construction of an industrial building, which has already been completed in recent years, as well as the initiated restructuring of the ceramic processing department, will be expanded in 2018 by a further 1.000 m² of a new building construction.
In addition to a new grinding plant for large-format blocks, this department will be used to set up a number of already existing saws, milling machines and lathes.


With this investment, P-D Refractories, Europe's largest producer of tin bath bottom and tank blocks, is responding to the increased demand of the container and float glass industry.  Furthermore, the steadily increasing quality requirements of machined shaped bricks, which are part of the core business of the Wetro site, are taken into account.
