Galvanized hexagonal net is a galvanized metal wire mesh, the shape of the grid is hexagonal.

The mesh size of the wire mesh specification, as well as the diameter and thickness requirements, are limited to the amount of steel and galvanized per square meter. Mainly in order to consider the corrosion resistance, prolong the service life, and in the use of the process of safety.

Of course, the quality of any product is also affected by the implementation of the manufacturer’s norms. If it is the manufacturer of electric welding mesh in production, it does not have a high implementation of the norms, or the procedural norms on the production line have decreased, or there is no higher requirements on the production link.

In addition to being built differently than other tapes, most electrical tapes used by professionals are UL Listed, which means that they have been vigorously tested for performance when exposed to environmental elements, such as cold temperature, moisture, and sunlight. UL Listed electrical tapes are also tested for physical properties, including backing strength, elongation, and adhesive strength and must meet a high standard in order to qualify for the listing. UL Listings exist for many other types of tape – such as foil and film HVAC tapes – but each listing revolves around the specific type of tape in question. So, while your foil tape may meet UL Listing requirements for sealing rigid ducts in HVAC applications, it would not meet the code if used in an electrical application.
