Premium refractories built for intense heat applications and superior performance
Our castable refractory is a specialized mixture containing heat-resistant hydraulic cement and premium binders designed to be cast in place for optimal performance. This versatile material finds extensive applications across various industries as well as in studio ceramics. Its popularity in kiln construction stems from its exceptional ease of use, simple mixing process, and cost-effective pricing structure.
We manufacture refractory mortar using an advanced engineering formula that combines high-quality sand, calcium aluminate, cement, and fireclay. This carefully balanced composition is specifically designed for laying firebrick in environments exposed to extreme temperatures. Important Note: Our refractory mortar is intended exclusively for constructing fire places and should never be applied directly to hot faces where it could compromise performance or safety.
Engineered to endure temperatures exceeding 3000°F (1650°C)—ideal for furnaces, kilns, and molten metal contact.
High abrasion resistance and low porosity prevent wear, cracking, and corrosion—even under rapid thermal cycling.
Tailored mixes (alumina, silica, low-cement) for precise applications—optimized strength, thermal shock resistance, and longevity.
Pumpable, self-leveling, or vibratable—reduces labor and downtime with quick curing and seamless application.
