What are the testing items for steel mesh and what are the standards?

How to handle the steel mesh inspection report? What are the steel mesh inspection items and standards? BAIJIAN third-party testing agency provides steel mesh inspection report processing. Engineers provide one-to-one service and select the corresponding inspection standards and projects according to needs, and formulate After testing the plan, arrange for the laboratory to send samples for testing. The steel mesh inspection cycle is 3-15 working days, and can be expedited (except for special projects). Welcome to consult.
