ZIBO HITECH MATERIAL Co., Ltd is one of the most specialized Pier Blocks Refractory Shape manufacturer and exporter in China.
Our Pier Blocks are made from a specially-formulated refractory castable that is extremely resistant to damage from thermal shock or cycling. Ordinary pier blocks can deteriorate rapidly due to cracking and crumbling caused by extreme variations in temperature over a short period of time. This cycling is typical in most car-bottom or box type heat treating furnaces. With the use of this thermal-shock resistant refractory, Pier Blocks are able to withstand this thermal cycling with relatively minimal damage over the lifetime of the block.
