As a leading manufacturer based in Hengshui, Hebei, China, Anping County Boli Hardware Wiremesh Products Factory (established in 1998) specializes in producing high-quality grouting expanded metal mesh with ribs for demanding civil engineering applications. Our 2.0mm thickness, 15x30mm mesh, hot dip galvanized product is engineered specifically for tunnel lining and slope stabilization projects, offering superior bonding strength, excellent drainage, and long-term corrosion resistance. With over two decades of manufacturing experience and annual export value exceeding US$5 million, we deliver reliable solutions trusted by engineers worldwide.
This ribbed expanded metal mesh is designed to enhance the mechanical interlock between shotcrete and rock or soil surfaces, making it ideal for grouting and support systems. The hot dip galvanized coating ensures protection against harsh underground environments, while the 2.0mm base thickness provides robust structural integrity. Below we detail the key specifications, advantages, and frequently asked questions to help you make an informed decision.

Product Features & Benefits
- Enhanced Mechanical Bonding: The raised ribs create a three-dimensional surface that increases the interlock with shotcrete, reducing the risk of delamination in tunnel linings and slope stabilization.
- Corrosion Resistance: Hot dip galvanizing provides a thick, uniform zinc coating that withstands aggressive underground environments, extending the service life of the mesh significantly.
- Optimal Mesh Geometry: The 15x30mm diamond pattern balances open area for grout penetration with sufficient steel coverage for structural support, ensuring efficient load transfer.
- Lightweight & Easy to Handle: Despite the 2.0mm thickness, the expanded metal is lighter than solid sheets, making installation faster and reducing labor costs on site.
- Versatile Application: Ideal for both tunnel primary support and permanent slope stabilization systems, compatible with various grouting materials and shotcrete methods.
- Customizable Dimensions: We offer tailored sheet sizes, rib heights, and strand widths to meet specific project requirements, including curved panels for tunnel arches.
Our manufacturing process ensures consistent quality: raw steel is precisely slit, expanded, and then passed through a hot dip galvanizing line. Every batch is inspected for dimensional accuracy and zinc coating thickness. With over 20 years of export experience to markets including North America, South America, Europe, and Southeast Asia, we understand the stringent standards required by international contractors.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between your ribbed mesh and standard expanded metal?
A: Our ribbed mesh features raised strands (ribs) that increase the surface area and mechanical interlock with shotcrete, providing superior bonding compared to flat expanded metal. -
Q: Can you provide curved sheets for tunnel arches?
A: Yes, we can customize the mesh into curved panels to match the tunnel profile. Please provide the radius and dimensions for a tailored solution. -
Q: What is the typical zinc coating weight for hot dip galvanized mesh?
A: Our standard HDG coating is approximately 85-120 μm (microns) per side, meeting ASTM A123 requirements. Heavier coatings are available upon request. -
Q: Is the mesh suitable for both wet and dry shotcrete?
A: Yes, the mesh works effectively with both methods. The open diamond pattern allows for proper encapsulation of the mesh by the shotcrete. -
Q: How do I calculate the required quantity for my project?
A: We recommend consulting with a structural engineer. As a general rule, the mesh coverage area should match the shotcrete layer. Contact us for technical sheets and guidance. -
Q: Can you supply mesh in rolls or only sheets?
A: Standard supply is in flat sheets. For specific applications, we can discuss roll options, but note that rolled mesh may have reduced rigidity. -
Q: What is the lead time for a container order?
A: Typically 15-25 working days after order confirmation, depending on quantity and customization. We can expedite for urgent projects. -
Q: Do you offer free samples for testing?
A: Yes, we provide small samples (e.g., 300mm x 300mm) for evaluation. Shipping cost is negotiable based on your location.
