When selecting welded wire mesh, it's essential to consider materials, specifications, and processes to ensure it matches project requirements. The following is a selection guide based on professional standards to help you avoid common pitfalls:
Matching Application and Specifications: First, clarify the application scenario. For example, concrete pavements require high compressive strength, so prioritize mesh with a wire diameter of 4-8mm and an aperture of 60-100mm; bridge deck paving requires fatigue resistance, so a wire diameter of 6-10mm is preferable. Avoid products with excessively large apertures or wire diameters to prevent insufficient load-bearing capacity.
Inspecting Material Quality: Low-carbon steel wire should have a smooth surface and be free of rust. This can be verified through a simple test: using a hardness tester, the Vickers hardness value should be within the range of 150-200 HV. Simultaneously, check product certifications, such as ISO 9001 quality management system, to ensure reliable material sourcing.
Evaluating Welding Process: Welds should be uniform, strong, and free of incomplete welds or burn-through. When purchasing, request the supplier to provide a weld tensile strength test report (standard value not less than 90% of the wire strength). Products manufactured by automated welding machines generally have better consistency and reduce human error.
Pay attention to dimensions and tolerances: Mesh specifications (e.g., 1*2m) must conform to the design drawings, and the aperture tolerance should be controlled within ±5mm. The wire diameter range (e.g., 2-12mm) should be clearly marked to avoid deviations that may cause construction problems.
