Rock Wool Blanket with Wire Mesh is a durable industrial insulation material designed for high-temperature and mechanically demanding environments. It consists of high-density rock wool fibers securely stitched with high-temperature-resistant wire to a galvanized or stainless steel hexagonal wire mesh reinforcement (typically on one side). Our rock wool blanket with wire mesh is engineered for large-diameter pipes and vibrating equipment. The SS304/Galvanized mesh ensures structural integrity under extreme mechanical stress.
This reinforced construction enhances the blanket's structural integrity and sag resistance, making it widely used for insulating large-diameter pipes, boilers, vessels, storage tanks, and irregular industrial equipment where both excellent thermal performance and mechanical strength are required.

About Us
FAQAnhui Liluan Technology Co., Ltd. is an industrial manufacturer specializing in high-performance thermal insulation and acoustic materials since 2009. We operate advanced, automated production lines delivering rock wool, glass wool, and ceramic fiber solutions engineered to meet rigorous international standards for global industrial, commercial construction, and architectural acoustics projects.
The stitched wire mesh (typically galvanized or stainless steel) provides essential mechanical reinforcement for heavy-duty industrial applications:
Tensile Strength & Vibration Resistance: The mesh holds the stone wool matrix securely together, preventing sagging, tearing, or fiber separation under high-vibration conditions (such as power plant ducts or industrial exhaust systems).
Adaptability to Irregular Surfaces: It allows the flexible blanket to wrap tightly around large-diameter pipes, valves, boiler walls, and spherical vessels without losing structural uniformity.
Mesh Variants: We offer Galvanized Iron (GI) mesh for standard applications and Stainless Steel (SS304 or SS316) mesh for highly corrosive chemical or marine environments.
Our wire mesh rock wool blankets are engineered for extreme thermal environments and heavy-industry infrastructure:
Thermal Threshold: Capable of continuous operation at temperatures up to 650°C (1200°F) without binder degradation or loss of insulation efficiency.
Core Applications: Primarily specified for high-temperature insulation in thermal power plants, petrochemical storage tanks, industrial furnaces, oil refinery towers, and large-scale district heating pipe networks.
Global industrial project tenders demand strict material purity and performance consistency:
Standard Compliance: Our products are manufactured in strict accordance with ASTM C592 (Standard Specification for Mineral Fiber Blanket Insulation and Blanket-Type Pipe Insulation).
Low Shot Content: Advanced centrifugation technology minimizes non-fibrous particles (shot), ensuring a higher ratio of effective thermal fibers. This yields lower thermal conductivity and a lighter, more manageable product.
Density Selection: Available in project-specified densities from 60 kg/m³ to 120 kg/m³ with uniform thickness tolerances to guarantee zero thermal bridging.
We optimize international supply chain operations for industrial distributors and contractors with a comprehensive service matrix:
Custom Sizing & Roll Optimization: Tailored adjustments to blanket lengths, widths, and thicknesses to match specific engineering drawings and layout requirements.
Compression Packaging for Logistics: Utilizing heavy-duty vacuum rolling technology to maximize container loading capacity, significantly reducing ocean freight costs per square meter.
Technical Submittal Documentation: Provision of independent quality certifications, factory test reports (MTC), and compliance data sheets required for engineering approval.
Global Port Dispatch: Secure palletization and fast customs clearance via major shipping hubs, including Shanghai, Nanjing, and Wuhu ports.
