Xinmi, Zhengzhou — the heart of China’s refractory industry. Built to supply, engineered to perform.
Founded in 1993 in Xinmi, Zhengzhou — the geographic center of China’s refractory industry — we’ve spent over three decades engineering solutions for steel mills, cement plants, glass furnaces, and non-ferrous smelters across more than 60 countries. We are not a trading company that resells bricks.
We are the manufacturer. Every brick pressed, every castable mixed, every batch fired under our roof — by our team, on our equipment, to our quality standards.
Plenty of suppliers call themselves manufacturers. Here’s what it means when we say it:
Two production bases across 60 acres — dedicated lines for shaped bricks, castables, ceramic fiber, and custom-profile products. No subcontracting.
6 CNC hydraulic presses (200t–400t). In a kiln lining, a 3mm gap can initiate thermal bypass and accelerated wear. Precision matters before the first heat.
Standard stock ships within 72 hours. Custom profiles delivered in ≤35 days. New mold tooling for non-standard shapes: as fast as 3 days.
Computer-controlled automatic batching eliminates batch-to-batch formula variation — the root cause of inconsistent field performance.
Highland Refractory is headquartered in Xinmi — a city recognized as China’s Refractory Capital, supplying a significant share of the world’s high-grade bauxite. Geographic proximity to raw materials isn’t a marketing point. It translates into tighter quality control and more competitive pricing.
Verified for Al₂O₃ content before every production batch. Chemical testing is upstream — not downstream.
Shanxi high-grade bauxite and Inner Mongolia magnesia for elevated-performance specifications.
Highland Refractory’s R&D and Testing Center covers 2,300 square meters and operates with a team of 35 technical specialists. We hold multiple invention and utility model patents, and maintain long-term joint research programs with:
For customers with non-standard operating conditions — unusually high slag basicity, thermal cycling above 1,600°C, or aggressive atmosphere profiles — our engineering team develops application-specific formulations before recommending a product. We don’t upsell. We specify correctly the first time.
Every production batch passes through a documented quality process before leaving our facility:
| Quality Checkpoint | Standard Applied |
|---|---|
| Raw material incoming inspection | Chemical composition + particle size verified per batch |
| Forming & dimensional check | CNC-pressed, ±1mm tolerance, 100% visual inspection |
| Firing & thermal performance | 77m tunnel kiln, 72-hour controlled firing cycle |
| Finished goods testing | Cold crushing strength, bulk density, refractoriness |
| Third-party verification | SGS / TUV on request; samples retained 12 months |
| Export packaging | Fumigated wood casing + honeycomb cardboard + steel strapping |
Our export packaging damage rate: ≤0.8% — versus an industry average of 5–8%. One number that procurement teams notice immediately.
Responsive technical support is a baseline expectation in this industry — not a differentiator. Here’s what we commit to, in writing:
Technical solution issued for any field problem reported
On-site arrival for domestic emergency situations
Full fault clearance target from initial report
