Bridge reinforcing mesh, as the name implies, is primarily used in bridge construction. Its introduction replaced the manual tying of steel bars, serving as a new type of reinforcing material for concrete structures. Bridge reinforcing mesh is a type of mesh formed by cold-rolling and straightening low-carbon round steel bars, which are then arranged in both longitudinal and transverse directions at a certain spacing using equipment. All intersection points are welded together using resistance spot welding. Reinforcing mesh is not classified by the type of steel, such as hot-rolled (Grade 1, 2, 3) reinforcing mesh, cold drawn smooth surface reinforcing mesh, or cold-rolled ribbed reinforcing mesh.
The bridge reinforcement mesh is a mesh composed of longitudinal and transverse rebars arranged at a certain spacing and forming right angles to each other, with all intersection points welded together. It plays an immeasurable role in bridge construction. According to information, the quality acceptance of over a thousand bridges in the country shows that the use of welded reinforcement meshes significantly improves the quality of the bridge deck paving layer, with the qualified rate of the protective layer thickness exceeding 97%, the flatness of the bridge deck improved, nearly no cracks on the deck, paving speed increased by over 50%, and the cost of bridge deck paving reduced by approximately 10%. It is mainly applied to the deck paving of municipal and highway bridges, reconstruction of old bridge decks, and crack prevention of bridge piers.
Reinforcing Mesh
The welding process of the bridge reinforcing steel mesh is fully computer-controlled, ensuring stable welding quality and mesh spacing without compromising the original strength and cross-sectional area of the steel bars. The use of steel mesh sheets saves 30% to 40% in steel, shortens the construction period by 80%, reduces labor costs by 60%, and significantly lowers overall costs, yielding substantial economic and social benefits.
