The tortoise shell mesh is a newly developed large-format mesh produced in our factory. It is commonly used to reinforce high-temperature monolithic refractory linings. Standard mesh is made of carbon steel (A3F), while 0Cr13 stainless steel is used in special cases.
Installation is performed in two steps: first, the mesh is spot-welded to the inner wall of the boiler or hot air duct; then, the refractory material is applied over it.

The hexagonal, large-claw-shaped mesh greatly enhances the anchoring of the refractory lining material. This reinforcement improves the bonding performance of the lining, helping to prevent peeling or detachment of the heat-resistant insulation layer.
The hexagonal mesh is used to reinforce unshaped refractory linings and is compatible with a wide range of lining materials.
Material and specifications:
■Standard grades: A-grade carbon steel (0Cr13), 1Cr13, 0Cr18Ni9, and 1Cr18Ni9Ti
■Mesh spacing: 2–8 cm
■Mesh thickness: 0.8–6.0 cm
■Plate thickness: 1–3 mm
■Mesh sizes can be customized according to buyer specifications
We collaborate with major equipment manufacturers to produce metal components and have supplied various structural metal parts for linings to numerous petrochemical equipment manufacturers. Our products are widely used in large-scale petrochemical plants, especially as key components in catalyst unit linings, enhancing the wear resistance and overall strength of the refractory lining.
Application details:
■General areas (reactors, primary and secondary cyclone separators, U-tube regenerator flues): carbon steel (A3F) hexagonal mesh
■High-temperature areas (regenerators, primary and secondary cyclone separators): alloy (1Cr13) hexagonal mesh
The hexagonal mesh is formed from 20 × 17.5 mm flat steel strips and attached to the end plate of insulation nails, providing a robust anchor for the refractory lining.
The tortoise shell mesh combined with a wear-resistant ceramic coating is primarily used in the cement industry for:
■Vertical mill classifiers and pipelines from the mill outlet to dust collectors
■Four-row dust collectors, feeding hoppers, and feeding chutes
■Grate coolers and point dust collector steel pipes
■C1 cyclone outlet pipes and bends
■Wear-resistant straight pipes and bends for pulverized coal conveying at the kiln head and kiln tail
■High-temperature fan housings and inlet/outlet ducts
■Circulating fan housings and inlet/outlet ducts
In addition, it can serve as a key wear-resistant and anti-corrosion layer for various high- and low-temperature equipment in the defense, petroleum, and chemical industries.
This next-generation material replaces conventional wear-resistant ceramic sheets and steel, helping to mitigate wind classifier erosion, impact wear, and frequent component downtime for maintenance across multiple industries.
