Ask for more than just refractory concrete. Ask for services that you won’t find anywhere else. Refractory concrete is not fire clay. It is a much tougher, stabler and more resistant material. However, a poor choice of shaped blocks or materials may cause cracking or premature wear in your shaped blocks. But we know what we’re doing. Even before we test-cast your first shaped blocks, we can tell you whether the shape you’ve proposed is suitable for your application.
