Brief Description:
Laurel produces a comprehensive range of fire clay brick consisting of 30-55% of alumina. All of our fire clay brick exhibit excellent strength.
In more arduous environments, we offer a hand fired " super duty" fire clay brick with a very high mechanical strength. Typically, our firebrick range is based upon flint clay giving it both a low iron and low alkali characteristic. It is resistant to thermal shock, abrasion, chemical attack. A wide range of sizes are held in stock.
