The manufacturing processes for brick reinforcement mesh fall primarily into two categories: stamping/expansion and butt-welding (or "top-welding"); a prefabricated component method is also utilized.
Stamping/Expansion Process
Stamped brick reinforcement mesh is produced from thin galvanized steel strip via a specialized stamping and expansion process in a single operation. Typically supplied in coils with a standard thickness of 0.35 mm and widths such as 6 cm or 10 cm, the mesh features a regular longitudinal arrangement of elongated apertures. The mesh strands form an upright hexagonal structure, with widened reinforcing ribs along both edges and a V-shaped rib pressed into the center. This design results in a seamless, robust, and integral structure offering high tensile strength as well as excellent resistance to pressure, vibration, and temperature fluctuations.
Butt-Welding (Top-Welding) Process
Butt-welded brick reinforcement mesh is manufactured by welding galvanized or high-quality low-carbon steel wires. Available in configurations such as ladder-style and truss-style (triangular), these meshes are characterized by having all wires lie in the same plane. More advanced automated production utilizes "top-welding" technology, encompassing steps such as wire feeding, straightening, welding, and cutting. For instance, the patented "Top-Welding Brick Reinforcement Mesh Production Line" (CN201920146099.4) enables the automatic stacking of welded mesh panels; the system is noted for its simple structure, reduced labor intensity, and neat stacking capabilities.
Prefabricated Component Process
Based on the patent for the "Manufacturing Method for Brick Reinforcement Mesh," this process involves welding a connecting mesh (ideally with triangular or rectangular openings) between two parallel metal wires-typically 3–5 mm in diameter-to form a prefabricated framework. This structure allows for mass industrial production; during construction, the mesh is placed directly into the brickwork or concrete wall. This eliminates the need for manual rebar cage tying while effectively increasing the wall's transverse and longitudinal tensile strength, as well as its seismic and crack resistance.
