SK32 SK34 SK35 SK36 SK38 Fire Clay Brick For Industrial Furnaces

Leadsun produces a full range of fire clay bricks with 30–65% alumina, all providing excellent strength. For more demanding conditions, we supply hand-fired “Super Duty” fire clay bricks with exceptionally high mechanical strength.

Made from flint clay, our firebricks feature low iron and low alkali content and deliver superior resistance to thermal shock, abrasion, chemical attack, and reducing atmospheres. They are ideal for a wide variety of industrial applications.

A wide range of standard sizes is available from stock, with custom sizes produced on request.
