When selecting diamond mesh, the usage environment, load-bearing requirements, and aesthetic needs should be considered . For example, 316 stainless steel is recommended for coastal areas to resist chloride ion corrosion, 310S heat-resistant stainless steel is suitable for high-temperature environments, and brass or copper can be considered for decorative purposes. It is recommended to conduct professional load calculations and corrosion assessments before purchasing, and to request the supplier to provide third-party testing reports, such as ASTM A740 or GB/T 26941 standard test data.
The inspection methods for diamond mesh include appearance inspection, dimensional inspection, and mechanical property inspection. Appearance inspection is carried out by visual observation combined with measuring tools such as vernier calipers, angle gauges, and tape measures. Dimensional inspection requires randomly selecting 5% of the mesh sheets from each batch, with no less than 3 sheets, and measuring the key dimensions of each sheet. Mechanical property inspection requires selecting 3 samples from each batch and entrusting a third-party laboratory to conduct tests according to standards.
Acceptance rules stipulate that the pass rate for appearance and dimensional deviations is not less than 95%, and all mechanical properties must be qualified. For any non-conforming items, one rework is permitted, after which a re-inspection is required. If the second inspection also fails, the entire batch will be returned or scrapped. The relevant technical parameters and acceptance procedures can be found in national standard GB/T 33281-2016 and other technical specifications.
