Key features

Lightweight Design: Bulk density ranges from 0.3 to 1.3 g/cm3, reducing furnace weight significantly.

High Thermal Efficiency: Low thermal conductivity (0.18-0.55 W/m.k) ensures excellent insulation performance.

Thermal Shock Resistance: Withstands rapid temperature changes without cracking due to closed pore structure.

Corrosion Resistance: Strong resistance to corrosive gases and slag in industrial furnace environments.

OEM/ODM Customization: Supports customization from samples and designs for specific industrial needs.

Quality Assurance: ISO9001 certified with strict pre-shipment inspection and compensation policy.

Wide Application: Ideal for insulating linings in electric power, metallurgy, and petrochemical kilns.

AI-Powered supplier vetting

SummaryThe supplier is a professional refractory-material and kiln-engineering supplier with capabilities covering shaped and unshaped refractory materials, castables, refractory cement, wear-resistant ceramics, graphite electrodes, kiln equipment, and related engineering services. It provides 3D design, sample/design-based customization, ODM, and OEM services, but reported no new products during the past year and has no SDK. Production information indicates two production lines and stated annual capacities including 100,000 tons of refractory bricks, 30,000 tons of refractory castable, 30,000 tons of refractory cement, and 50,000 tons of another refractory castable category. Quality and management certifications include CE, ISO9001:2015, ISO45001:2018, and ISO14001. Service procedures, complaint handling, corrective actions, and finished-product inspection are documented and followed. However, the supplier lacks overseas agents, branches, warehouses, and showrooms, and has no valid manufacturing-capacity...

Supplier typeThe supplier explicitly identifies as a professional technical supplier and operates across refractory materials, castables, ceramics, graphite electrodes, kiln equipment, and kiln-related engineering services. This indicates a specialized industrial supplier rather than a general trading entity.

CertificationsThe supplier reports CE product compliance certification and ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. These stated certifications provide explicit evidence of formal quality, occupational safety, and environmental management coverage.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions, customer complaints, supplier-service assessment, and quality assurance, and it maintains in-stock service capability. However, it has no overseas warehouse, showroom, agent, or branch, so overseas physical service support is limited.

R&D capabilityThe supplier has three R&D engineers and provides 3D design, ODM, and OEM services, demonstrating design and development capability. However, it reported no new products in the past year and has no available SDK, so evidence of recent product innovation is limited.

Production capacityThe supplier operates two production lines and reports substantial annual capacities, including 100,000 tons of refractory bricks, 30,000 tons of refractory castable, 30,000 tons of refractory cement, and another 50,000-ton refractory castable category. It has defined equipment and finished-product inspection instructions, but lacks a valid contract between the factory and related subcontractor, creating a documented capacity-governance concern.

Customization capabilityThe supplier explicitly offers customization from samples and designs, 3D software design services, and ODM services. These combined capabilities directly support customized product development and manufacturing.
