How to Avoid Demand Planning Pitfalls in Refractories

By Glazix | May 30, 2025

A Step-by-Step Breakdown for Leaders Under Pressure

In refractories distribution, a missed forecast isn’t just inconvenient—it can derail an entire shutdown project, destroy cash flow, or leave high-value customers exposed. With volatile end markets like steel, glass, and cement, demand planning must be treated as a leadership discipline—not a back-office task.

The Common Pitfalls—and How to Fix Them

1. Over-Reliance on Historical Averages

Past performance doesn’t predict future demand—especially when customer shutdown schedules shift or raw material markets spike.

✅ Solution: Use rolling 13-week forecasts updated with customer pipeline insights and external demand signals (steel output, construction permits, etc.)

2. Ignoring Plant Maintenance Schedules

If you’re not mapping your top 20 accounts’ kiln, furnace, or plant turnaround windows, your forecast will always be off.

✅ Solution: Use account managers and field service data to log key shutdowns 3–6 months out.

3. One-Size-Fits-All Inventory Rules

Applying the same safety stock formula to dense bricks, insulating castables, and patching products guarantees waste.

✅ Solution: Segment inventory policies by material class and customer profile.

4. Disconnected Sales and Operations Planning (S&OP)

If sales forecasts aren’t communicated to production and purchasing, you’re managing supply blind.

✅ Solution: Monthly S&OP meetings, with sales providing quote-based forecasts and ops challenging assumptions.

5. No Contingency for Raw Material Risk

Magnesia, alumina, and silica inputs often face multi-week lead times or price shocks.

✅ Solution: Build scenario-based forecasting. What if lead time extends from 6 to 12 weeks? What if freight doubles?

Better Planning Starts with Better Data

Track quotes and RFQs by product group

Align inventory visibility with customer project phases

Invest in forecasting software that reflects refractory SKUs and BOMs

The Strategic Payoff
