REFRACTORY BRICKS FIRE CLAY BRICKS INSULATION BRICKS FIRE BRICKS
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.
