There are many manufacturers that produce welded wire mesh, but how can we distinguish whether the welded wire mesh produced by the manufacturer is qualified? "Some manufacturers cannot provide a certificate of conformity for the inspection of welded wire mesh, and the welded wire mesh will still be released into the market. Therefore, when purchasing welded wire mesh, how should we identify whether the quality of the welded wire mesh is acceptable?". In terms of the quality of the welded wire mesh, the error in the wire diameter of the welded wire mesh should be controlled within 0.02mm. For example, if we purchased a welded wire mesh with a wire diameter of 89 wires, we need to measure the diameter of the wire with a micrometer. The allowable range for the diameter is 87-91 wires, so it is a qualified welded wire mesh within this range. However, no one can control the consumption process so well. Due to the loss of distance or other reasons, the wire diameter of the welding mesh is around 0.01 mm, so the error is allowed.
The tensile resistance of the welded wire mesh must reach 120N, otherwise it will be considered as an unqualified welded wire mesh. There is no simple way to test the tensile resistance of welded wire mesh in this aspect of tensile resistance. Only through tool and expert testing, can we not introduce it in detail. The exposed ends on both sides of the welded wire mesh shall not exceed 2MM, which is considered as a qualified welded wire mesh. The radial wire and weft wire of the welding mesh should be welded firmly, but if the edge of the welding mesh is to be welded firmly, some weft wires can be pulled out, so that the welding can be strong, but not too much. Generally, the welding mesh that does not exceed 2mm is qualified.
There are also some external phenomena: the quality of the mesh holes should be uniform, and the hot-dip galvanized layer of the hot-dip galvanized welding mesh should be evenly distributed, so that the anti-corrosion effect can be better. The materials of the welding mesh used in the project are also different, including hot-dip galvanized welding mesh, cold galvanized welding mesh, and wire drawn welding mesh. Among them, the hardness of the wire drawn welding mesh is larger, and the construction difficulty is greater than the first two. Using hot-dip galvanized welding mesh is relatively easy to construct, Because of its better flexibility, it needs to be flat after paving, making it easier to hang ash.
