Refractory hex mesh is a type of robust hexagonal metal mesh used in refractory lining reinforcement for furnaces, reactors and kilns. Hex Mesh for refractory lining is made in 3D dimensional cellular honeycomb structure, this structure can provide robust support and excellent bonding to the refractory material, while allowing for flexibility and adaptability to various surface contours.
Refractory hexagonal mesh is adaptable to complex shapes to improve the overall performance of thermal insulation systems, main features:
- Thermal Shock Resistance: Withstands rapid temperature changes without compromising structural integrity.
- Heat Containment: The hexagonal pattern effectively traps heat, minimizing heat loss and enhancing insulation.
- Flexibility and Adaptability: Accommodates expansion and contraction of refractory materials, reducing the risk of cracking.
- Erosion and Corrosion Resistance: Provides a strong barrier against wear and chemical damage, ensuring long-term durability.
Refractory Hex Mesh is widely used in high-temperature operations, for reinforcement of Large Furnace Lining Structures Of Pipelines In Power Plants, Cement Plants, Petroleum, Smelting Plants and Steel Making Plants.

Three-Dimensional Honeycomb Structure
This structure consists of interconnected hexagonal cells, creating a robust and flexible mesh suitable for high-temperature industrial applications.
Design and Construction
- Hexagonal Cells: Each cell in the honeycomb structure is hexagonal, providing a high strength-to-weight ratio. This design distributes stress evenly across the mesh, enhancing its structural integrity.
- Interconnected Framework: The hexagonal mesh cells are interconnected, forming a continuous, seamless network. This interconnected framework ensures that the hexmesh can withstand significant mechanical and thermal stress without deforming or failing.
- Three-Dimensional Depth: Unlike flat meshes, the three-dimensional honeycomb structure has depth, allowing it to provide superior support and reinforcement for refractory linings. This depth also contributes to hexmesh’s ability to accommodate expansion and contraction of the refractory material.
Functional Benefits
- Enhanced Thermal Shock Resistance: The three-dimensional honeycomb structure allows for efficient heat transfer while providing excellent resistance to thermal shocks. The interconnected hexagonal cells can expand and contract, reducing the risk of cracking under rapid temperature changes.
- Improved Heat Containment: The hexagonal mesh cells trap small pockets of air, which act as insulating barriers. This insulation minimizes heat loss and helps maintain a stable temperature within the refractory lining, enhancing energy efficiency.
- Superior Erosion and Corrosion Resistance: The robust interconnected framework provides a strong barrier against erosion and chemical corrosion, hence ensures the longevity and reliability of the refractory lining, even in harsh industrial environments.
- Flexibility and Adaptability: The three-dimensional honeycomb structure is inherently flexible, allowing it to conform to various shapes and surface contours.

Notes of construction:
- All measurements are provided in millimeters (mm) .
- Ensure hexmesh fits against the lining surface of the ring and outlines the boundary of the plate.
- Install hexmesh tightly against the surface of the plate using the rolling method indicated in the diagram.
- Test the hexmesh and edging bar with a 500gm hammer from a height of 300mm to check for any loose or broken welds, which must be removed and replaced.
- Visually inspect the welds to ensure they adequately penetrate through the hexmesh and into the underlying metal.
- Use the same material for the edging bar, end tab, punch tabs, and corner rabs as used for the hexmesh. Ensure all parts meet client specifications.
- Minimize the length of the hexmesh to prevent overheating during refractory application.
- Ensure all bridging pieces are welded securely to the shell.
- Wire brush or clean the entire surface area before applying refractory material.
