Description
Hot dipped galvanized after welding wire mesh has a uniform color and a clean, flat silver-gray texture. It has no local color differences, no exposed iron, and no blackening marks from welding, resulting in a more aesthetically pleasing overall appearance. It is very suitable for engineering, landscaping, and fencing projects where appearance is important.
Requirements for the zinc layer
For hot dipped galvanized after welding wire mesh, we place even stricter requirements on the zinc layer, as it is the final production step and effectively guarantees performance. Our requirements for the zinc coating primarily focus on the following aspects:
Zinc coating thickness
According to the GB/T 13912-2020 production standard, for heavily corrosive environments, the zinc coating thickness must be ≥70μm; for general use, it must be ≥45μm. Products outside this range are considered unqualified.
01
Adhesion
A bend test is conducted on finished, hot dipped galvanized after welding wire mesh. Extensive peeling of the zinc coating is prohibited, ensuring a strong bond between the zinc layer and the substrate.
02
Uniformity
A copper sulfate immersion test is used to verify that no metallic copper precipitates after four cycles of testing, ensuring uniform coverage of the zinc coating on the mesh surface with no localized unevenness.
03
Surface quality
The zinc coating must be uniform in color, with no noticeable color variations, and free of defects such as sags, cracks, or missing plating. This ensures satisfactory performance while enhancing the appearance.
04
In which fields can we give priority to hot-dip galvanized wire mesh after welding?
For which applications is hot dipped galvanized after welding wire mesh a good choice? We can consider three aspects: corrosion resistance at weld points, strong zinc adhesion, and excellent weather resistance:
Heavy-duty outdoor protection
Heavily polluted environments such as chemical plants, smelters, and mines; highway and railway barriers; and airport runway safety nets.
Agricultural and livestock farming
In coastal areas or saline-alkali lands, where soil and groundwater are high in salt, hot dipped galvanized after welding wire mesh can protect against salt corrosion and extend its service life.
Municipal engineering
In areas exposed to acidic and alkaline wastewater and sludge, the hot-dip galvanizing layer resists chemical corrosion, preventing rust, clogging, or breakage, ensuring a stable sewage treatment process.
