Concrete reinforcing mesh
The Reinforcement Mesh is an indispensable component of present-day architecture, and it comprises of welded wire fabric. This fabric is made from robust tensile steel wire, which is welded into square or rectangular meshes, used for reinforcing concrete structures. It finds its application in diverse domains, spanning from industrial to residential structures, involving beams, floors, roofing, wall panels, concrete pavement, bridge pavement, tunnel lining, and many more.

Concrete reinforcing mesh description
Concrete reinforcing mesh is an indispensable component of modern building projects and belongs to the category of welded wire fabric. High tensile steel wire is utilized in manufacturing it, which is then welded into rectangular or square meshes, to serve as concrete reinforcement. This versatile product finds extensive use in industrial and residential constructions, such as walls, roofs, flooring, beams, bridge pavements, concrete pavements, tunnel linings, and so on. Being a top manufacturer of concrete reinforcing mesh, Weijia offers a range of galvanized concrete reinforcing mesh with varying mesh sizes, opening sizes, and diameters.

Introduction to concrete reinforcing mesh for Tunnel Support
The tunnel concrete reinforcing mesh is also referred to as reinforcement mesh, reinforced mesh, welded fabric, or welded steel wire mesh. It is crafted by welding longitudinal and transverse bars together, forming a 90-degree panel.
- Installation Procedure of concrete reinforcing mesh
Upon placing the anchor bolts in the tunnel, the necessary concrete reinforcing mesh is conveyed and incorporated. The concrete reinforcing mesh panels are securely welded onto the anchor bolts and joined together for utmost structural stability.
- Enhancing Tunnel Safety Through International concrete reinforcing mesh Standards
The utilization of concrete reinforcing mesh during the application of shotcrete serves to heighten the shear and bending strength of shotcrete in compliance with the international JTG70-2004 standard. It also facilitates the enhancement of cement's punching resistance, fortification against bending fatigue, and minimization of shrinkage, while simultaneously minimizing the risk of falling blocks.
- Concrete reinforcing mesh For Tunnel Support Specifications
The concrete reinforcing mesh commonly comes in a rectangular shape and is characterized by a variety of mesh spacings that usually range from 150mm to 300mm. The most common choices include 150mm x 150mm, 200mm x 200mm, 200mm x 250mm, 250mm x 300mm, and 300mm x 300mm. Additionally, it is crucial to ensure that the connection length of the steel mesh should be at least 30 times the wire diameter (30d).
- Shotcrete Protection Layer
The shotcrete protective layer combined with oncrete reinforcing mesh should have a minimum thickness of 20mm. In the case of two layers of oncrete reinforcing mesh, the spacing between them ought to be no less than 60mm.
