One week ago, Highland Refractory successfully secured a new order from a steel manufacturing client in Poland for 25 tons of high-quality fire clay bricks.
all refractory bricks have now been fully manufactured, inspected, and prepared for shipment, and are currently being loaded for delivery to the port.
This ongoing project highlights our capability to deliver customized refractory solutions with stable quality and reliable lead times for European industrial clients.
The client is a mid-to-large-scale steel processing company in Poland, operating continuous heating furnaces for metal treatment and shaping processes. Due to the demanding nature of their operations, the furnace lining materials are exposed to:
Continuous high temperatures ranging from 1200°C to 1400°C
Frequent thermal cycling (heating and cooling)
Mechanical stress and abrasion from materials handling
Before working with Highland Refractory, the client experienced several issues with their previous refractory supplier:
Premature cracking and spalling of bricks under thermal shock
Short service life, leading to frequent shutdowns and maintenance
Inconsistent product quality between batches
Delayed delivery times, affecting production schedules
As a result, the client was actively seeking a reliable refractory brick supplier capable of delivering consistent quality and stable supply.
After a detailed technical consultation, our engineering team recommended a tailored solution using high-performance fire clay bricks, optimized for the client’s furnace conditions.
These bricks are specifically designed for medium to high-temperature industrial furnaces, offering excellent balance between cost and performance.
Al₂O₃ Content: 35% – 45%
Refractoriness: ≥ 1500°C
Bulk Density: 2.0 – 2.2 g/cm³
Cold Crushing Strength: ≥ 25 MPa
Permanent Linear Change: Low shrinkage at high temperature
To meet the specific requirements of the Polish client, we provided:
Customized brick dimensions to fit the furnace design
Optimized raw material formulation to improve thermal shock resistance
Strict dimensional tolerances for easier installation
Our solution ensured that the bricks could withstand repeated thermal cycling without structural failure, significantly improving furnace stability.
At Highland Refractory, we understand that consistent quality is essential for industrial clients, especially in Europe where standards are stringent.
The production of these fire clay bricks followed a controlled process:
Selection of high-quality raw materials (calcined clay, bauxite)
Precise batching and mixing
High-pressure shaping
Controlled drying process
High-temperature sintering in tunnel kilns
This process ensures uniform structure, high density, and excellent thermal properties.
Each batch underwent comprehensive testing, including:
Dimensional accuracy checks
Visual inspection for cracks or defects
Cold crushing strength testing
Refractoriness verification
We ensured that all products met international standards and client specifications before shipment.
Efficient and safe delivery was a critical part of this project.
To prevent damage during long-distance transportation, we used:
Fumigated wooden pallets
Moisture-proof wrapping
Reinforced strapping for stability
Production Time: ~45 days
Loading Port: Qingdao Port, China
Destination: Major port in Poland (Gdansk)
Shipping Method: Sea freight (CIF terms)
We coordinated closely with the logistics team to ensure on-time delivery without delays, helping the client maintain their production schedule.
After installation and operation, the performance of the fire clay bricks exceeded the client’s expectations.
✅ Enhanced thermal stability under continuous high temperatures
✅ Significant reduction in cracking and spalling
✅ Extended service life of furnace lining
✅ Reduced maintenance frequency and downtime
The improved durability directly contributed to lower operational costs and higher production efficiency.
The client expressed strong satisfaction with both the product quality and service:
“The bricks perform very well under high-temperature conditions. We see a clear improvement compared to our previous supplier. Highland Refractory is a reliable partner with stable quality and professional support.”

Fire clay bricks are widely used in industrial furnaces, kilns, boilers, and fireplaces due to their excellent heat resistance and durability.
The service life depends on working conditions, but high-quality fire clay bricks can last several years under proper installation and operation.
Yes, especially when properly formulated, fire clay bricks offer good thermal shock resistance, making them suitable for applications with frequent temperature changes.
Production and delivery typically take 30–45 days, depending on order quantity and customization requirements.
High-Temperature Resistance: Withstands up to 1350°C continuous operation. Energy Efficiency: Low thermal conductivity reduces heat loss. Lightweight & Durable: Easy to handle and long-lasting. Wide Application: Steel, glass, ceramic, chemical, and energy industries.

70% Alumina Fire Brick is a high-performance refractory material, composed of approximately 70% aluminum oxide (Al₂O₃). Manufactured from high-quality bauxite or synthetic raw materials, these bricks undergo high-pressure molding and high-temperature firing to achieve superior durability. With excellent resistance to high temperatures, thermal shock, and chemical corrosion, 70% Alumina Bricks outperform ordinary clay or lower-alumina bricks in strength, refractoriness, and erosion resistance. These characteristics make them an ideal choice for industrial furnaces, kilns, and other high-temperature equipment. Compared to ordinary clay bricks or refractory bricks with 50%–60% aluminum content, 70% alumina bricks offer higher refractoriness, better compressive strength, and stronger erosion resistance. This makes them a mid-to-high-end refractory material with excellent cost-performance, suitable for industries that demand reliable, long-lasting, and heat-resistant linings. Highland Refractory provides high-quality 70% alumina bricks that meet international standards, ensuring stable performance for diverse industrial applications.
Curved firebricks—also known as curved refractory bricks, arch bricks, or shaped fireclay/alumina bricks—are essential refractory components used in high-temperature industrial furnaces that require circular, arch, dome, or cylindrical structures. Their curved geometry allows furnaces and kilns to maintain structural stability under high thermal load while minimizing stress concentrations typically found in straight-lined refractory designs. With excellent refractoriness, corrosion resistance, thermal shock performance, and mechanical strength, curved firebricks are widely applied in steel, petrochemical, ceramics, non-ferrous metal smelting, and energy industries.
