Laurel produces a comprehensive range of Fire clay brick consisting of 30-55% Alumina all of which exhibit excellent strength. For 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. Resistance to thermal shock, abrasion, chemical attack and reducing atmospheres are just some of the key criteria determining choice of product within each application. a wide range of sizes are held in stock.
Alumina silica fire brick is a premium refractory material designed for high-temperature industrial furnaces and kilns. Combining superior thermal stability with mechanical strength, this brick ensures durability in harsh operating conditions. Available from professional alumina silicate brick suppliers, it is suitable for standard and customized applications.
Combining durability, thermal efficiency, and customization, alumina silica fire brick, supplied by professional alumina silicate brick suppliers, and custom alumina silicate brick solutions provide reliable performance for demanding high-temperature industrial applications.
