We're currently reviewing grounding materials for an industrial electrical project, and copper earthing strips seem to be one of the most recommended options. From what I've learned, they offer excellent electrical conductivity, good corrosion resistance, and a long service life when installed correctly. However, I'm curious about what people usually check before purchasing. Do you focus on copper purity, strip dimensions, manufacturing standards, or testing certifications? I'd like to avoid selecting a product that performs well initially but requires frequent maintenance later.

While researching different grounding solutions, I came across Akaaltech, which manufactures earthing and lightning protection products, and it made me wonder how professionals compare manufacturers in this field. For those who have worked on industrial plants, commercial buildings, or infrastructure projects, what has your experience been with copper earthing strips? Are there any common installation mistakes or quality issues that buyers should watch out for before placing a bulk order?
