refrctory brick

refrctory brick: 1. High refractoriness 2. Good wear and corrosion resistance 3. High mechanical strength

Refrctory brick  :

Zibo Bunge Ecological Building Materials Co. Ltd is a professional manufacture and exporter of Clay Brick and refractory, it is the Clay Brick production base which is operated and supplied technology by Shandong Research and Design Institute of Ceramics. We use the third generation pusher kiln which can produce the brick with stabler color, better durability and higher strength.

 

Our brick is made by high temperature sintered clay. The strength of the brick is more than 45mPa. Our products are popularly used in Traffic Lanes, Garden, Square, Villa, Residential Area and Municipal Project and sell well both at home and abroad, especially the water permeable sintered bricks which are exported to Korea, Japan, USA, Germany and so on.

 

Zibo Bunge warmly welcome all the customers and foreign friends to our company investigating and guiding and is looking forward to our friendly long-term cooperation.
