Manufacturing Process: Precision and Quality Assurance

The manufacturing of Construction Reinforced Steel Bar Welded Wire Mesh is a highly automated and precise process, ensuring consistent product quality that surpasses manual fabrication. The process begins with carefully selected raw materials, typically high-strength deformed or plain steel bars compliant with international standards such as ASTM A615/A706 or BS 4449. The transformation into finished mesh involves several critical stages:

Process Flow Overview:

1. Raw Material Procurement & Inspection: High-grade steel wire rods or bars are sourced and undergo rigorous inspection for chemical composition, mechanical properties (tensile strength, yield strength), and surface integrity to ensure compliance with relevant material specifications.
2. Straightening & Cutting: The steel bars are fed into automated machines that straighten them and cut them to precise lengths according to the required mesh dimensions. This step minimizes material waste and ensures dimensional accuracy.
3. Automated Resistance Welding: Longitudinal and transverse bars are precisely positioned perpendicular to each other. High-current, low-voltage resistance welding electrodes then apply pressure and heat at each intersection, forming a fusion weld. This automated process ensures uniform weld strength and consistent mesh geometry across the entire sheet.
4. Quality Control & Testing: Throughout the production, continuous quality checks are performed. This includes visual inspection, dimensional checks (bar spacing, overall sheet size), and destructive testing of weld shear strength (e.g., in accordance with ASTM A1064/A1064M). Manufacturers also adhere to ISO 9001 quality management systems.
5. Finishing & Packaging: Once verified, the mesh sheets are bundled, labeled, and prepared for dispatch. Options for galvanized or epoxy-coated mesh for enhanced corrosion resistance are also available depending on project specifications.

This stringent manufacturing process ensures that the finished product boasts a service life comparable to the concrete structure itself, often exceeding 50-100 years under normal conditions, particularly when used in target industries such as civil infrastructure (roads, bridges), industrial construction (foundations, heavy-duty slabs), and precast concrete manufacturing.
