What we supply

Factory-formed and ready to set.

Precast refractory shapes are cast, pressed, or formed from castable, plastic, or insulating material under controlled factory conditions, then shipped cured and ready for installation. Complex geometries that would require days of skilled field work arrive on the truck ready to set.

Burner Blocks & Tile

Precisely formed to match burner geometry in high-alumina and silicon carbide formulations. Resistance to flame impingement and thermal shock is engineered into the mix design.

Corbels & Ledge Tile

Structural support shapes for suspension systems and load-bearing applications. Designed to your dimensional specs with adequate embedment for mechanical anchoring.

Arch Segments & Roofs

Sprung arch and flat roof sections in modular segments. Reduces arch-forming time from days to hours. Available in fireclay, high-alumina, and IFB compositions.

Nose Rings & Transitions

Rotary kiln nose rings, hood shapes, and transition pieces where standard brick is impractical. Segmental design accommodates thermal expansion.

Flue Liners & Ducts

Round, square, and rectangular sections for hot gas handling and combustion chambers. Spigot-and-socket or flat-end joining configurations available.

Custom Engineered Shapes

Submit a drawing or CAD file. We work with producers who can form virtually any geometry. Prototype and production quantities available.

Replacement programs: measure, cast, deliver

Red Stick Industrial Supply can coordinate measurement of worn precast components during an outage, arrange casting to exact original dimensions, and have replacement shapes ready before the next scheduled shutdown. Reduce your outage duration by having parts on hand before the furnace comes down.

Advantages over field-formed castable

Field castable requires forming, pouring, curing, and drying before the furnace can heat up. Precast shapes arrive ready to install.

Consistent density — factory QC vs. field conditions
No on-site forms required — lower installation labor
Reduced dry-out time; moisture already driven out at factory
Complex shapes achievable that brick or field castable cannot replicate

Ordering and lead times

Standard shapes are often available short-run or from stock. Custom shapes require engineering review — plan 6–12 weeks ahead for critical path items.
