Refractory materials for high-temperature industrial applications, including spinel bricks. We supply shaped and unshaped refractories — magnesia spinel, high-alumina and fireclay brick, castables, mortars and insulation — selected against the service temperature, atmosphere and chemical attack in your kiln, furnace or boiler.
- Product class selected against service temperature, atmosphere and chemical attack
- Chrome-free magnesia spinel for cement kiln burning zones
- Shaped brick to ISO kiln shapes plus specials cut to drawing
- Installation data sheets, heat-up curves and quantity take-off support
