Import Fire Clay Insulating Brick — Buy in Bulk from Supplier in China

Fire clay insulating bricks from Henan Lite Refractory Material Co., Ltd. are refractory products designed for thermal insulation in industrial furnaces and kilns. These bricks have a bulk density of 0.6 to 1.0 g/cm³ and operate within a temperature range of 1100°C to 1400°C, based on standard industry classifications for fire clay insulating materials. The thermal conductivity at 350°C averages between 0.15 and 0.25 W/m·K, which supports significant energy savings in continuous high-temperature operations.

The bricks are manufactured from selected fire clay with controlled alumina content, typically between 30% and 40%, and contain minimal impurities such as iron oxide and alkali metals. They are formed using a low-pressure extrusion method and fired in tunnel kilns to achieve controlled porosity. This results in a structure that resists thermal shock and maintains dimensional stability under cyclic heating, a standard performance trait for Class A insulating bricks in the refractory industry.

These bricks are commonly purchased by ceramic kiln operators, glass manufacturers, and metallurgical plants for lining furnace walls, arches, and roofs. Buyers typically order in palletized quantities of 1 to 5 cubic meters, with packaging in plastic-wrapped wooden crates. Trade terms are commonly FOB Zhengzhou or CIF port of destination, and lead times average 20 to 30 days after deposit confirmation. Buyers should confirm batch-specific thermal conductivity test reports before shipment.

Henan Lite Refractory Material Co., Ltd. is based in Zhengzhou, Henan Province, and operates as an imported supplier with harbor trust tier verification. The company’s profile confirms production and export activity in refractory bricks but provides no details on factory size, employee count, or years in operation. It does not list certifications, client names, or revenue figures. The listing indicates active export channels but does not confirm response rates or customer service capacity.

The supplier’s location in Zhengzhou places it within a major refractory manufacturing cluster in central China, near access to raw clay sources and rail logistics. The company does not claim ISO certification, SGS validation, or any third-party quality assurance in its listing. Buyers should treat all claims as unverified unless confirmed directly with the supplier through documented test reports or audit records.
